Document Summary
General information: vital link between the brain and the rest of the body, functional independence from the brain, serve as a pathway for sensory and motor impulses, responsible for reflexes aka the quickest reactions to a stimulus. Sectional anatomy of the spinal cord: between left and right communication occurs through the grey commissure of the grey matter. Inner grey matter region: dominated by dendrites and cell bodies of neurons and glial cells and unmyelinated axons, centrally located: anterior, posterior and lateral horns, gray commissure: surrounds central canal, communication. Location and distribution of gray matter: anterior horn: cell bodies of somatic motor neurons, lateral horn: cell bodies of autonomic motor neurons, posterior horn: axons of sensory neurons, cell bodies of. Interneurons: cell bodies of sensory neurons are actually found in the. Location and distribution of white matter: anterior, posterior, later funiculi, axons within white matter organized into tracts, remember, no cell bodies in white matter, just axons!
