tympanic membrane

Anatomy & Physiology Overview - The Ear

Outer ear 

  • Pinna (auricle) - visible part of the ear outside of the head.  
  • External auditory canal 
  • Ceruminous glands - specialized sudoriferous glands (sweat glands) located subcutaneously in the external auditory canal. They produce cerumen (earwax) by mixing their secretion with sebum and dead epidermal cells.

 Middle ear: air filled 

  • Tympanic membrane -  vibrates in response to sound waves 
  • Malleus, incus and stapes - 3 small bones that transmit vibrations to each other

Inner ear: fluid filled 

  • Mechanoreceptor for hearing and balance 
  • Vesibular apparatus - balance
  • Semicircular canals 
  • Cochlea
  •  • Organ of Cor -  sensory epithelial cell

Cochlea

  • Perilymph = similar in compositon to plasma – Na+ 
  • Endolymph = high in K+ 
  • Organ of Cor: contains hair cells – move due to pressure waves 
  • 50-100 stereocilia on each cell 
  • Longest embedded in tectorial membrane 

In the cochlea that the vibrations transmitted from the eardrum through the tiny bones are converted into electrical impulses sent along the auditory nerve to the brain. 

  • The cochlea is a tapered tube which circles around itself 
  • The basilar membrane divides the tube lengthwise into two fluid-filled canals joined at the tapered end. 
  • ossicles transmit vibration to the cochlea where they attach at the oval window
  • resultant waves travel down the basilar membrane where they are “sensed” by  16-20,000 hair cells (cilia) attached to it which poke up from a third canal called the organ of Corti
  • Organ of Corti transforms the stimulated hair cells into nerve impulses 
  • Waveforms travelling down the basilar membrane peak in amplitude at differing spots along the way according to their frequency 
  • Higher frequencies peak out at a shorter distance down the tube than lower frequencies
  • The hair cells at that peak point give a sense of that particular frequency
  • The distance between pitches follows the same logarithmic distance as our perception of pitch i.e. the placement of octaves are equidistant.
Beholder Anatomy - Part 1 - External Anatomy

Beholders are perhaps the most deadly of the great monsters of the D&D World.

They are certainly one of the most distinctive and unusual in appearance.

The original beholders are said to have been spawned on one of the Outer Planes by a primal entity as powerful as a deity.

This creature has no name, and its children have no need to generate one for it.

To others, it is known only as the Great Mother, a name granted more for the fact that the creature spawned the entire beholder race from its very flesh than for any real certainty that it is female.

From the Great Mother, the beholder race and its various kin have propagated to the other planes with great success, for few can stand in the way of such destructive creatures.

Although the information in this is presented as fact, beholders are alien creatures in body, mind, and soul…

Huntress 2


Had a request for a continuation of the huntress story, so i put something together. It could probably keep going further if people want… so… see what you think.


-—

The following is composed of excerpts retrieved from the logs found in the remains of rescue vessel fgd-22583. Compiled, organized, and annotated for inquiry 894438hf.

Log# 44889390hjk43- fgd-22583 contacted by command and rerouted to intercept and investigate the loss of contact with research vessel rhd-777421. Eta- 3 cycles to contact target.

**-Note- transcript of reroute orders available under appendum 4, orders do not mention nature of rhd’s research, nor does it note the brief activation of rhd’s emergency beacon.**

Capt. Contact report- Rhd detected and approached. No visible signs of damage, or violence. Scans indicate hull is uncompromised, however main power appears to be offline. Minimal life support appears to be active on secondary particle decay power system. No response to hails. Boarding team assembled and shuttlecraft deployed.

*transcript from video record of commander of boarding team ‘Comdr. Tuluth’*

Tuluth- “It’s cold in here. (image shows Hatch is heavily frosted over.). Do you have that door wired up?”

Pvt hervs- “Almost Sir. It’s cumbersome in these gloves.”

(Door opens, revealing a hallway lit by emergency lighting)

The smell was what hit them first. A cloying metallic stink that their bodies reacted to instinctively with revulsion. It was the scent of danger… of messy and violent death. They reflexively shut their nose slits to the onslought. “Damn that stinks.” Hervs said, stating the obvious.

“Keep sharp. Something bad happened here.”

“Think they were attacked?”hervs whispered

“I don’t see any signs of being boarded or attacked. No weapon damage to the hull, or signs of much fighting here.” Tuluth said, moving into the hall, weapon at the ready.

The ship was eerily silent, Tuluth began shouting to try to rouse any survivors. His voice echoed flatly against the walls, and brought no responses. He keyed the com link with a clawed thumb. “There’s no sign of the crew. We’re going to go to engineering and see if we can restart main power. I don’t see anything wrong with the ship. Maybe we can pull up records.”

“Affirmative.” The captain’s voice crackled over the com.

They were just becoming more comfortable, and began walking faster through the halls. They nearly walked through the first section of old smeared blood dried against the decking before they realized what they were looking at. The sheer volume of area covered was unexpected. “With an edge of surprise and shock, Tuluth keyed the mic again. “We have blood on the floor. A lot of it. No body though.”

“Perhaps after you get power up, the next stop should be medical.” The captained responded.

“Aye.”

They found themselves beginning to move steadily faster to the engineering section, before skidding to an abrupt and horrified halt outside the door.

“Holy Egg.” Hervs said breathlessly. “Those are bones!”. He was correct. Bones of the crew were piled haphazardly along the sides of the hallway.

Tuluth leaned down and picked up a skull. These were not simply bodies that had fallen. These bodies had been dismembered, and cast about. Scratches on the skull suddenly clicked in his mind. “These have been cannibalized.”

“What?” Hervs said looking at the bones with somehow even greater horror.

“They were eaten. Those scratches are knife marks.” He looked up at the door to engineering. “Engineering would be the warmest part of the ship, near the particle decay core. If they are still here, they are probably in there.” He gestured to the sealed door looming before them. They girded themselves and pressed forward. Tuluth keyed in the code, and the door parted, revealing what could only be described as a house of horrors. Hervs reflexively vomited on the floor before him.

The remaining bodies of the crew had been butchered. The meat must have been kept frozen elsewhere in a colder section of the ship, but here the work of separating edible from not had been done. Gore streaked panels sat before them, and a partially dismembered corpse hung from the network of conduits above them. “Egg. What madness happened here?” Hervs whispered.

“Someone must have gone insane, and murdered the others.” Tuluth responded.

“Are they still here?” His eyes were wide and searched the room.

“Could be. Keep your guard up. Lets just get tHe logs loaded and leave. Let someone else untie this mess.” Tuluth stepped carefully into the room, and quickly found the needed console. Relieved, he could see it was already active. He connected his com unit, and initiated the information transfer.

“Did you hear that?” Hervs said starting to pant with panic.

Tuluth strained his tympanic membranes, but detected nothing unexpected. “I just hear the ship thermally creaking.”

“I thought something moved.”

“Lets just hurry.”


Excerpt from Capt. log- **Upon review of the boarding party’s recommendation, the target ship has been tagged for salvage with a note of severe biocontamination from crew remains. Beacon has been affixed and activated. Recovered data regarding several weeks of intensive testing done on one of two unidentified organisms has been included with the dispatch and final report returned to command involving this incident.**

360 Centicycles after contact with the derelict craft, engineering began noting an unusual level of subsystem failures. Life support, thermal regulators, and internal illumination, all suffered a 500% increase in minor failures reported throughout the ship. Why this was not noted by engineering staff is unknown. The failure of the main communication array and location beacon is the first system failure properly logged, noted, and responded to in any recorded capacity. Ensign Yuta, was dispatched to make repairs via access shaft 67.

*Note following partial autopsy report*

Medical casualty report, 34. Ensign Yuta. Apparent cause of death is extreme electrocution and accompanying heat damage. Burns are extraordinarily severe, carbonizing approximately 85% of all tissue. Official cause of death- misadventure.

A log note in engineering was made indicating that during the second attempt to repair the array, it was observed that the death of Yuta had caused secondary damage to the array, and repairs were deemed impossible at the time. Wording used by repair crew included,”Torn to pieces” “ripped out” and “unlike any simple failure {they had} ever seen”. No other logs were made which indicated mechanical issues, prior to the cessation of main power, and any official logs.

The following was drawn from the personal recording device of Commander Ojoft. Timestamp on the recording indicates that only 60 Centicycles had passed since power failure.

“It’s in the walls. ITS IN THE WALLS!!!” Ultge screamed, firing his rifle blindly into the ceiling and walls until all of his ammunition was spent. Ojoft covered his head, and stayed low behind the piled debris he was using for cover. “EGG! Ultge! Calm down!” Ojoft yelled, hands still over his membranes.

“Calm!?! How can we be calm!? Whatever killed everyone on that ship came here, and now it’s killing us! WE’RE DEAD ALREADY!! WE’RE ALLL DEAD!!” Ultge ran from the room screaming, disappearing down the darkened hallway before suddenly falling silent with a gurgling chirp. Ojoft stared into the darkness, barely breathing. A small round object spun back from the hallway, rolling roughly along the deck. Ultge”s head came to a stop before blinking once at him. Ojoft froze. The human strode out of the darkness, and into the room. Blood-slicked, muscular, and wide shouldered, it was slightly smaller than Ojoft himself. It was brandishing Ultge’s spent rifle like a club. It waved the rifle in the air, and called out loudly. He was watching the human, terrified, and heard the sound above him far too late. The last thing Ojoft ever saw, was the smaller human, squealing and barking a maddening pattern of titters, falling upon him from the vent it had crawled through. Its soft, yet frustratingly resilient skin stretched rather than tore as his thicker skin did. Her paws dug into him, tearing and rending him. He didn’t even have time to scream.

———————

It is the opinion of this council, following review of the logs and reports following this incident which resulted in the loss of two fully crewed interstellar vessels, that the organisms classified as “Humans” Should be avoided at all cost. No further specimens are to be collected, and any planet found to contain them is to be blacklisted for indefinite quarantine. It has also come to the attention to the council that a full shuttlecraft is unaccounted for in the review of debris. Location of this shuttlecraft should be made a priority activity for the good of the race.

Part Two (Part One can be found here.)



Captain Lik-Jennings in all her glory stared down at Adri. Adri the human from Earth. Adri, whose business tag labeled her as “Corporate Philosopher” (Lik-Jennings had taken a class concerning the planet Earth three years ago and was faintly sure Earthen philosophy was a thing of the past, but had learned to never be sure with humans). Adri, who kept annoyingly rocking back and forth in anticipation.

“So,” the captain began, adjusting the translation device cupped around her tympanic membrane. 

“So,” Adri mimicked, nervously. She also wore a translating device. The deckhand who had dumped the female here watched on from a few paces behind. 

“So,” the constant repeated, businesslike. “You’re the human journalist that’s been sending me fanmail for the past five years.”

Adri nodded. “I—yes. That’s me.” The tiniest of smiles formed in the middle of her small, pale face. 

Lik-Jennings nodded back to show she was knowledgeable in human body language and customs. “I see. And now you’re here.”

“I—Well, journalism got boring,” Adri admitted, fiddling with her name tag. Lik-Jennings waited for the female to elaborate, but she did not continue speaking and only gazed off the bow of the ship. The cosmos beyond were an impressive sight. It was the first time Adri wasn’t seeing them from behind the screen of her suite’s window in Geyser Technologies’s production tower.

“…And you’re wanting to become part of the crew? I understood that much from your letters, I think, but co-organizing your own escape and leaping out of a building into the vacuum of space just to be with us…?”

Adri stood up taller. “I’m calling it ‘trying something new,’ but yeah, basically.”

Lik-Jennings was now confused. “What do you mean by ‘trying something new?’ Is that your only reason?” She exchanged glances with her second mate. “You haven’t just escaped from prison? Your parents weren’t murdered by an arch-nemesis? You want to join just like that? Because your old job was ‘boring?’”

The human dipped her head bashfully, but still met the captain’s eyes. The captain knew she would not back down. “Yeah, I guess. Just because.” She looked around again, at all the deckhands watching them. “I read news about you guys all the time, and, well…it seemed…fun?”

Ah, so it was the romantic aspect that was making her do this. Lik-Jennings grinned, or did the equivalent of grinning her own anatomy would allow. “You’re doing it for…‘fun.’ Well. I’ve heard all these crazy stories about your species, but this time I can finally see reason in your endless determination.”

Adri perked up. “Oh, thank god. You don’t think I’m crazy.”

Lik-Jennings shook her head. “Oh, no, I definitely think you’re crazy. All of you Earthlings; you’re in for more than you’re asking for. But that doesn’t stop you from wanting and trying, does it.”

There, again–the tiniest of smiles. “Nope.”

Base of skull fractures can produce the clinical signs seen in my caretoon:

  1. ‘Raccoon eyes’ AKA periorbital bruising
    This is bruising around the eyes, sometimes seen with tarsal plate sparing; this is where the bruising doesn’t cover the upper eyelid, which contains the ‘tarsal plate’, a small area of connective tissue which helps stop the eyelid inverting when opening and closing the eye.
  2. Blood or CSF rhinorrhoea (nose leakage) and otorrhoea (ear leakage)
    These fluids may leak from the nose or ear. CSF is cerebrospinal fluid; the clear fluid which surrounds the brain and spinal cord.
  3. Haemotympanum
    This is blood seen behind the eardrum (AKA tympanic membrane) when using an otoscope, the tool a doctor uses to look inside the ear canal.
  4. ‘Battle sign’ AKA postauricular bruising
    Bruising may appear behind the ear.

These clinical signs occur in base of skull fractures, when the cracked bone, or trauma that caused it, results in damage to the blood vessels or/and brains covering, allowing leakage of their contents into these areas of the head and neck.

They make up a classic set of signs emergency doctors will look for when assessing patients who have had a head injury. They can be a marker of how severe the trauma has been, and alert medics to consider further imaging (scans) to go looking for further damage or compromise to structures within the skull.

These signs are important ‘free information’ to pick up if you have a sharp eye!

“The most dramatic auditory visions occur with music. Just as any object radiates a pattern of electrons and can become the essence of all energy, so can any note of music be sensed as naked energy trembling in space, timeless. The movement of notes, like shuttling of oscillograph beams. Each capturing all energy, the electric core of the universe. Nothing existing except the needle-clear resonance on the tympanic membrane. Unforgettable revelations about the nature of reality occur at these moments.”

Okay, an update on the Thelma and Louise (‘Pia has two tumours named Thelma and Louise’) situation!

If you’re new to this situation, I have a thing called Hereditary PGL/PCC or PGL1 or the SDHD variant or gene fault. It is incurable. And it makes me grow tumours. It’s also known as the paraganglioma/pheochromocytoma thingie, which are very rare endocrine tumours that are rather horrid and never benign, even if they’re not metastatic. It’s also known as  'you have para what?’ and 'how do you pronounce that again?’ and 'geez, I’m a doctor and I still have never heard of it’ and 'is that cancer?’

I currently have two paragangliomas. Both on the right hand side of my neck. One is a carotid body paraganglioma that sits nicely between the internal and external carotid arteries (this is bad for the arteries, they couldn’t save them the last time I had a carotid body paraganglioma on the left hand side). The other is a glomus vagale tumour that is growing in the vagus body of the vagus nerve, and this one is large enough to be pushing my arteries apart, and is a little too close to the jugular and the tympanic membrane and skull case. A hungry glomus vagale will happily eat the skull and penetrate into the brain, but…so far that’s not happened to me. *crosses fingers*

  “The Soul Swims in the CSF”

 In fact, the brain and spinal cord, which contain the largest volume of cerebrospinal fluid (CSF) in the body, do literally “swim”, or float, in CSF. Both are completely immersed in this liquid environment. Our Indian Master asserted that the brain and spine (spinal cord) are the altars of God in man.  He also stated that we worship God in the temple of the spine.

These assertions lend further credibility, from a metaphysical perspective, that the soul of man may physically express in and around the brain and spinal cord. The soul has been described as an individualized ray of God’s consciousness, which temporarily identifies with the mind/body. The soul can also be depicted as a personified portion of God resident within each human being. Although Dr. Stone passed on before the discovery of neuropeptides in the mid-nineteen eighties, he may have connected these informational substances with his statement that “the Soul swims in the CSF” had he been alive when neuropeptides were discovered.

Neuropeptides are informational substances that coordinate almost all physiological and emotional processes on a cellular level. They are literally responsible for the mind-body connection, for they serve as a point of transformation between the mind and body. The generally accepted definition of healing is to bring about a closer connection among mind, body and Spirit. Therefore, it is suggested that neuropeptides circulating in the CSF may be the physical substances that coordinate the mind, body and Spirit connection and facilitate healing on all levels.

Itzhak Bentov postulated that the body contains oscillators, which create a magnetic field that is connected with “EVERYTHING”, when all the oscillators are harmonized. His theory includes the following partial list of oscillators; aorta, heart sounds, circulatory sensory stimulus and standing waves in the lateral ventricles of the brain. The latter area is where CSF and some neuropeptides are produced and contains the largest reservoir of CSF in the body. Thus, it is proposed that when the CSF and neuropeptides are flowing optimally, it effects our consciousness in such a way that we can become united with the universal consciousness in “everything”. It is also suggested that this postulate may be given further credibility by the movement of a drum-like, tympanic membrane, in the roof of the lateral ventricles (corpus callosum) of the brain. It is suggested that this drum-like membrane may pick up cosmic vibrations, which set the CSF vibrating a in frequency connected to universal consciousness.

One great Indian Master defined God as, “ever-present, ever-lasting, ever-new joy”, and stated that God is in the “eternal” present. Depak Chopra, well known author and lecturer on spirituality, professes that when we are in the present moment, we are in the presence of God and God is present in us. These descriptions and statements about God directly lend support to what occurs, both experientially and physiologically, when the CSF and neuropeptides are flowing optimally.

Being in the “now moment”, or, more “present”, could be linked to the medullary centers in the brain, which control our sense of alertness. The CSF passes through the medullary center, and therefore may be related to the feeling of alertness, or being in the “here and now”-“the present”. This also may be connected to neuropeptides circulating in the CSF through the medulla and pons areas of the brain.

The bliss or joy that is experienced when CSF flows optimally may be related to an increased, or more completely natural, amount of serotonin circulating in the CSF. Serotonin is a large neuropeptide that is secreted into the CSF from the supraepindymal cells lining the ventricles of the brain, where CSF is produced and present in large volume. Serotonin levels are related to our sense of well being and mood. Therefore, as the CSF flows in an optimal fashion it may stimulate the supraepindymal cells to secrete serotonin. This could account for the heightened sense of well-being and elevated positive mood experienced when the CSF is flowing freely.

Another factor, which may play a role in our connection to “everything” on the planet and serotonin levels, could be the pineal gland. Metaphysically, the pineal gland is said to be responsible for our connection to the ‘rhythm of life’. The pineal gland in birds and reptiles is located close to the top of the head, is directly sensitive to light, and functions as a third eye.

In humans, the pineal gland is indirectly sensitive to light. It functions as a circadian pacemaker, which also regulates the secretion of melatonin and serotonin. The pineal gland is bathed in CSF from the superior cistern, and as the flow of CSF has been reported to increase at night, this flow could effect the pineal gland’s involvement in the daily “rhythm of life” in human beings related to the neuropeptide mechanism.

Pioneer neurosurgeon, Wilder Penfield, M.D., found a way to map the functions of large areas of the human brain. In the 1920’s at McGill University in Montreal, he conducted a startling series of experiments in which he reported the following observations. When he stimulated a region called the sylvian fissure, in the right temporal lobe of the brain in epileptic patients’, they commonly reported leaving their bodies, seeing God, hearing beautiful music, seeing dead friends and relatives, and vividly recalling significant life experiences. The theory that CSF flows in the glial cells system could explain the connection, as glial cells can be responsible for initiating and terminating seizures.

A great Indian Master claimed that the soul remembers every incarnation (past life), and that a God-conscious soul can commune with other souls previously deceased. The experimental experiences reported by Dr. Penfield could be related to the CSF and neuropeptides. The CSF cistern of the lateral fossa is between the temporal and parietal lobes of the brain and any increased stimulation of this area could be responsible for Penfield’s observations.

It has been suggested that meditation is practicing the “presence of God”. The Gamma brain wave pattern, associated with meditation, is produced in the temporal area of the brain, which may be related to CSF and neuropeptide flow in that area as well. The CSF cistern (reservoir), of the lateral fossa, bridges the lateral brain fissures (indentations) between the temporal and parietal lobes of the brain. Therefore, a more natural flow of CSF and neuropeptides could bear upon the production of the Gamma rhythm in the brain.

It is also suggested that the CSF may be responsible for the “Kundalini” phenomenon. Kundalini is a dormant, creative energy potential in nature and in the body. When it “awakens” in human beings, one effect is that soul qualities may emerge. The Kundalini energy flows up and down the cerebrospinal pathway in a manner very similar to the physiological movement of the CSF. The Kundalini phenomenon, on a physical level, therefore, may be related to an electromagnetic field generated by CSF flowing in rhythmic pulsation’s from the base of the spine up into the cranium and down again. The movement of the CSF molecules could generate this electromagnetic field, that according to recent research could be related to CSF flow.

It is possible that it is the movement of sodium and potassium molecules, electrolytes in the CSF that creates an electromagnetic energy field of various frequencies emanating from within the body. Since the CSF controls the electrolyte balance in the nervous system, it regulates the body’s ability to conduct electricity, which is an electromagnetic phenomenon. And recent research indicates that CSF is thought to influence the electromagnetic environment of the neurons and other cells of the central nervous system. Thus, the Kundalini phenomenon on a physical level could be related to a mechanism involving an electromagnetic field generated by the CSF. Perhaps then Dr. Randolph Stone’s intuition before the discovery of neuropeptides was correct and that the “Soul” utilizes the mechanism of these informational substances circulating in the CSF to bring about a closer connection among the mind, body and Spirit.

MOTH family Drepanidae (Hooktip Moths)

(click individual images for IDs in captions)

The Drepanid family of moths are distinguished from all others due to their sense of hearing (which is why the family includes some groups that are dissimilar in appearance to the classic “hook-tipped” moth but related by this feature). The abdominal ears of drepanids are structurally unique compared to those of other Lepidoptera and other insects, by having an internal tympanal membrane, and auditory sensilla embedded within the membrane.

marril96  asked:

If a person was to hear an extremely high pitched noise, would their ears bleed? If yes, how else would the sound affect them? Would anything else bleed (nose, eyes, other orifices???)? Would they get disoriented? Dizzy, perhaps? I'm giving a siren this ability and would really like to know how sound can damage a person's body. Please and thank you.

Heyhey! So let’s talk about ears, baby! (Let’s talk about you and me!) I could not f ind a gif of a siren blasting out somebody’s eardrums, so here is a puppy howling:

Originally posted by fortheloveofhuskies-blog

First off, the concept of ears bleeding because of a pitch , or frequency, of sound is a pure BS trope that Hollywood likes to play. Bleeding ears look dramatic, but human ears deal very well with extremely high pitch. Beyond a certain threshold we simply can’t hear it anymore. That’s it. The end.

However, the tympanic membrane (eardrum) can rupture because of volume. Sound exists in pressure waves, and the frequency of those waves is immaterial to your desired effect, but the amplitude (volume) is not. An extremely loud siren-character might be able to rupture tympanic membranes by producing overpressures.

Now, there are going to be some other effects from this, not the least on the sirens themselves; since this is SciFi™ I’m going to say that for that one, the Rule of Reality applies.

As to the victim, I’m now basically considering your siren to be a bomb, in terms of pressure waves. That means that the “blast” is going to produce results similar to primary blast injuries. Solid organs are going to do pretty well with this, actually, because sound  will just vibrate right through them. But hollow organs, especially the lungs, stomach, and small intestines, might run into problems, because all of a sudden the pressure on one side of a membrane is very different from that on the other.

In short, this could cause issues with internal bleeding in the lungs, and the gut. Also consider structural damage in a cone shape that radiates outwardly from your oh-so-loud siren. It could also potentially throw people backwards across a room.

Oh! One last point. As to your dizziness question: yes indeed, this could cause dizziness. Also deafness. And, uhh. Possibly death, if a building falls on them.

Best of luck and happy holidays!

Fact of the Day: You actually need both ears for horizontal lateralisation of sound!

For example, for someone who is deaf in one ear, if a phone rings they would be able to hear how high up the phone is, but not which side of the room it is in! While you only need one ear to detect the height (vertical localisation) of a sound, you need both to tell where the sound is coming from horizontally in relation to you. This is because the ear uses a different method of detection, in that for vertical localisation, the shape of the ear is used to direct the sound waves towards different areas of the ear drum (tympanic membrane), whilst horizontal localisation uses the lengths of the nerves of both ears. Essentially, the brain uses the difference in time it takes for a sound to reach one ear compared to the other (interaural time difference), to decide which direction a sound is coming from, which is why you need both ears to do so!

part 1 of seven rivers  series

Kookie was thirteen when he first saw his pale skin, small cat-like eyes and brown-reddish hair. Kookie thought his hair would look better if it were jet black. But it was not his place to voice his opinions so he just stood quietly, on his chair and waited for something to happen, something that would tell him that he is going to make it.

A dude came in and gave them, the rookies, a lecture from the bottom of his heart. His voice was too high pitched and Kookie couldn’t concentrate on all the talking about being an idol and what meant having a relationship in that cruel, cruel world.

He laughed, though, because everyone laughed, and his ears perked up at the sound next to him. He saw red gums and a flash of small, white teeth.

That night he dreamt of gummy bears.

Hello Doctor, thanks for answering our questions, you're awesome!
Now, I've got a question myself. I've had inner ear tubes (the ones that go into your eardrums) ever since I was 4, my first tube came out of my ear at the age of 11 and right now I'm 17 going on 18 and I've still got one of the tubes in my ear.
It's still in place, and it doesn't really give much problems. I do wonder, is it bad for an inner ear tube to stay in my ear for this long? I looked them up on the internet and it said it's supposed to stay in for like.. 2 yrs max.
Until recent years, I did have an ear infection each year, (in the ear with the tube) but I'm not sure what that's all about.. I have to wear an ear plug every time I shower and swim and it's becoming quite a hassle.. So that's why I'm wondering if this ear trouble is still necessary..

I am going to visit my throat nose + ear doctor in the near future (I hope somewhere this year) But I'd also like to hear your thoughts on this. :) Cheers!

Sounds like you have chronic otitis media secondary to tympanostomy, Pinky and the Membrane!

The “ear tubes” (tympanostomy tubes) create an opening in the tympanic membrane, which sits between your outer ear and middle ear. You’re right, they’re supposed to fall out on their own within a couple years, and then your body heals up the hole on its own. But if the tube stays in place, then it’s like having a direct pathway from your outer ear into your middle ear – a pathway for water to carry bacteria. (Dun dun DUNNNNN!) I’m glad you’re wearing your ear plug, which kinda helps block that pathway, but if I were you, I’d see the ENT about getting that tube removed (and possibly having the hole patched, if it doesn’t appear that it will heal over on its own) to help reduce your number of ear infections, which could lead to bony damage and eventual hearing loss.

Best of luck!
