Document Summary

Neurophysiology 1: organization & cell function (pages 227-236 ), describe the organization of the nervous system. Cns (brain and spinal cord) & pns (sensory neurons, motor neurons, interneurons: describe the functions of the afferent neurons, efferent neurons, and interneurons. Afferent neurons (sensory) is a long process extending from the nerve cell body that carries nerve impulses from sensory receptors toward the cns. Efferent neurons (motor) send impulses from the cns to limbs/organs. Interneurons communicate between afferent and efferent: describe the types and functions of the glial cells. Glial cells surround neurons and provide support for insulation between them. Oligodendrocytes provide support and insulation to axons by creating the myelin sheath that can wrap around multiple axons. Astrocytes support endothelial cells that form from the blood brain barrier, provide nutrients to the nervous tissue, maintenance of extracellular ion balance. Ependymal cells are the thin epithelial lining of the ventricular system of the brain and involved in the production of csf.
