Document Summary

Central nervous system = brain & spinal cord. Cerebrum (cerebral hemispheres) nuclei & gray matter. Cerebellum gray matter in nuclei and cortex. Cerebrum 83% of its mass, separated by longitudinal fissure. Thalamus: receives ascending sensory info, processes it, relays to cerebral cortex; sensation, motor activities, learning, memory: medial and lateral geniculate - relay visual and auditory info to cerebral cortex, midbrain. Hypothalamus: autonomic control center (bp, heartbeat, sleep cycle, food intake, digestive tract mobility); emotional response (pleasure, fear, rage, bio rhythms) *regulatory area: controls release of hormones, produces posterior pituitary hormones. Epithalamus: pineal gland secretes melatonin (regulate sleep-wake cycles), some input from retina: cerebral cortex - function: sensation, communication, memory, voluntary movement, motor areas voluntary movement. Olfactory, gustatory, vestibular cortices: association areas integrate diverse info. Prefrontal cortex- personality, abstract intellectual functions, long-range planning. Each hemisphere controls opposite side of body, not in equal function, no functional area acts alone; conscious behavior involves entire cortex.
