Recent technological and scientific advances have fuelled a neuroscientific revolution. Imaging techniques such as those shown above have given us an unprecedented view into the structure and function of our brain.
An English fossil hunter recently found
a small brown pebble that turned out to
be the first ever example of fossilized
dinosaur brain tissue. Despite its age,
many of the structures were preserved,
remnants of its networks, capillaries,
and blood vessels are still present, and
these remaining tissues show evidence
that dino brains may have been far
larger than we previously thought. Source
Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.The central nervous system is made up of the brain, spinal cord and nerves. The peripheral nervous system consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect to one another and to the central nervous system.
Functionally, the nervous system has two main subdivisions: the somatic, or voluntary, component; and the autonomic, or involuntary, component. The autonomic nervous system regulates certain body processes, such as blood pressure and the rate of breathing, that work without conscious effort. The somatic system consists of nerves that connect the brain and spinal cord with muscles and sensory receptors in the skin.
