The peripheral nervous system includes all spinal and cranial nerve fibers providing end organ innervation. A peripheral nervous system is further subdivided into the somatic and autonomic divisions; the latter of which can either be sympathetic (fight or freight response) or the parasympathetic (rest and relax response).
On gross inspection, nerves can be perceived as solitary, solid, white bands. But when looked under a microscope, we can see that each nerve fiber is actually composed of a large number of axons whose cell bodies reside in central or peripheral ganglia, the spinal cord or the brain.
On the full version of this video, we will be covering the following points:
- overview of the anatomy and histology of peripheral nerves;
- longitudinal section of a peripheral nerve;
- cross-section of a peripheral nerve;
- blood supply and innervation of peripheral nerves;
- clinical notes associated to peripheral nerves: peripheral neuropathy.
