PC3005 Study Guide - Final Guide: Vasomotor, Skeletal Muscle, Dermis
Document Summary
Nucleus = aggregation of functionally related nerve cell bodies. Ganglion = aggregation of like nerve cell bodies. Function: protect the neural tissue, provide a structural framework for arteries and veins of the brain and spinal cord. Role: cushioning and supporting the cns, circulatory function for removal of waste and supply of nutrients. Produced: in choroid plexuses, in all the ventricles. Means of monitoring and controlling some of our most important bodily functions. Only ventral primary rami supply the limb buds. Enter limb, split into anterior and posterior divisions: anterior divisions supply flexor compartment, posterior divisions supply extensor compartment. Examples: radial nerve = extensor/posterior, ulnar nerve = flexor/anterior, median nerve = flexor/anterior. Grey matter: contains cell bodies of neurons. White matter: contains mainly myelinated axons, myelin makes it white. Arrangement in spinal cord: white outside, grey inside. Arrangement in brain: grey outside, white inside.
