retinaculum

National Moth Week is July 22-30.⠀
.⠀
The world’s largest moth is the Atlas moth (Attacus atlas), and it has a wingspan of about a foot (30.5 centimeters). The largest butterfly, Queen Alexandra’s birdwing (Ornithoptera alexandrae), is roughly the same size. So what’s the difference between moths and butterflies?⠀
.⠀
Moths and butterflies fit into two categories: behavior and anatomy. For the most part, moths are nocturnal. They fly and feed at night. Butterflies, on the other hand, are diurnal, or active during the day. So the winged insect you see feeding from a flower in the middle of a spring afternoon is most likely a butterfly. If you watch a large-winged, flitting insect make its way toward a candle at night, it’s probably a moth.⠀
.⠀
Butterflies and moths also pupate, or become adults, differently. Both go through their metamorphosis in a chrysalis, or protective shell. Moths, however, often spin a silk cocoon around their chrysalis, sometimes camouflaging it with leaves or debris.⠀
.⠀
The physical differences between moths and butterflies are usually easy to see:⠀
.⠀
* Butterflies’ antennae are wider at the tips – their ends look like little clubs. Moths’ antennae are often feathery. Sometimes, they’re thin like butterflies’ antennae, but without the clubs.⠀
.⠀
* Most of the time, butterflies’ wings display more vivid colors than moths’ wings do. This doesn’t mean that moths only come in shades of white, brown and gray, though. The Actias artemis shown on the previous page is an Asian moth that is related to the similarly-colored luna moth. It’s colorful enough that it’s sometimes known as the night butterfly.⠀
.⠀
* Many moths use a series of loops called a retinaculum and a fringe called a frenulum to connect their front and rear wings. Butterflies don’t have these structures.⠀
.⠀
*Often, moths’ bodies are plumper and fuzzier than butterflies’ bodies.⠀
.⠀
But not every member of the order Lepidoptera fits neatly into the categories of butterfly and moth. There are butterflies with moth-like qualities and moths with butterfly-like qualities. https://www.instagram.com/p/BW2nEKQF7WO/

I’m super fucking pissed because I’ve learned the ligaments of the foot and ankle this morning in prep for lab and I did a lot of googling about my own ankle pain, and I’m about 100% certain that I tore my fibular retinaculum and displaced a tendon. This requires surgery. There’s no reason I should’ve had persistent pain for eight months. I’m extremely angry. I have the shittiest insurance, and to get this fixed I’ll have to spend something in the order of thousands of dollars because my deductible is so fucking high. 

And the specialist I saw said it was “just” tendonitis. I can barely afford another MRI holy fucking shit. How ironic that I want to be a doctor and I can’t afford medical care.

if doctors aren't trustworthy then that's really fuckin scary because then who is??? who can we ask these kinds of things????? you'd think doctors but apparently not

Hahahahaha. Welcome to my life, friend!

There are some doctors who are not awful. But, like. I’m chronically ill and disabled and so is the rest of my family, and after a while, you figure out that most doctors are, well, uh, pretty useless.

…I was going to type up a bunch of the experiences I’ve had, but I realized I can basically sum it up like this: my family has a lot of medical problems. 60% of them have been discovered on accident. The other 40% of them were discovered because we sat down and did our own research and brought it up to doctor after doctor until we found someone who would take us seriously (and lo and behold, we were right).

Your mileage is always gonna vary with doctors. Not all of them suck. But a lot of them do. Do not blindly trust doctors, please. So many of them are lazy, so many of them don’t know what they’re talking about but like to pretend they do (ever wonder why anatomical parts often have really weird, unpronounceable names? It’s because doctors like to pretend they are smart even if they don’t understand the phenomenon at all), and so many of them refuse to learn new things. And, worst of all for many of us, so few of them are trans-friendly.

I’m not saying “never trust a doctor again!” but I am saying “be wary of doctors, do not dive in headfirst to whatever they tell you, do your own research and if you are unable to do your own research find someone who is willing to help you and give you a fresh perspective”.

I am not saying this because I hate doctors. I have a lot of doctors that I really truly love. But when you know medical care as intimately as I and my family do, you realize that doctors are basically just like you and me, except they know what mean corpuscular volume is and where to find the flexor retinaculum (which are things that you can learn too). Sometimes. Not even always.

I am also not saying this because you should never see a doctor again, because they can be helpful. But for goodness’ sake: tread carefully, they are not the Bastions of Knowledge that we make them out to be sometimes.
