Document Summary

Central nervous system brain + spinal cord. Cerebrum: 2 hemispheres, contralateral sensation and movement. Cerebellum ring a bell motor control : two hemispheres, ipsilateral motor control. Brain stem: most primitive part of the brain, life functions. Spinal cord: info to and from the brain. Visceral system (autonomic nervous system: parasympathetic + sympathetic. 31 segments x 2 spinal nerves per segment = 62 spinal nerves. Dorsal root = sensory (dolphin"s have a dorsal fin, and they are. 5 regions: breakfast at 8, lunch at 12 dinner at 5 : cervical 8 spinal segments, thoracic 12, lumbar - 5, sacral 5, coccygeal 1. Each spinal segments receives sensory input from particular regions of body: on the skin surface: dermatome. None on the face 12 cranial nerves relay info of face: neurons/axons: Afferent info to a place (sensory to cns) Efferent info from a place (motor info from cns to target) Outer to inner: dura mater, arachnoid csf in subarachnoid space.
