Central Nervous System Anatomy of Brain (Figure 6-39) -Cerebral Cortex (cerebrum) -Grey matter (outer shell) -clustered cell body=nuclei -White matter (inner layer) -Axons (myelin is white) -Ventricles (4) -Chambers filled with cerebral spinal fluid. The four ventricles are Cerebrum, Diencephalons, Cerebellum, and the Brainstem -Back to cerebrum -Perception, voluntary movement, language, learning, memory -Diencephalons: -Thalamus: -Major relay station of motor control; crude sensation -Hypothalamus: -homeostatic regulation; link between nervous system and endocrine system -Forebrain= cerebrum and diencephalons -Cerebellum= balance, muscle tone, coordination -Brainstem= Key to life -Cardiac, respiration, digestion (swallowing + vomiting) -Brain death -Classic-all four not responding -functional- Forebrain not responding Anatomy of Spinal Cord: -Grey matter -interneurons cell bodies and dendrites of efferent neurons, axons of afferent, glials -White matter -bidirectional -Dorsal side= afferent -ventral side= efferent
