Document Summary
Central nervous system= brain and spinal cord: telencephalon= cerebrum. Gray matter= integrates neural input and output. Limbic system= higher cognitive function, emotional response: amygdala= express emotion, hippocampus= formation of memories. White matter= transmit signals: cerebellum= balance, planning, executing voluntary movement. Vestibulocerebellum= maintain balance and control eye movement. Cerebrocerebellum= input to cortical motor areas, store procedural memories: diencephalon. Thalamus= main integrating station for sensory info cortex. Epithalamus= connect limbic system to other brain parts. Pineal gland, habenular nucleus: brainstem=midbrain, pons, medulla. All ingoing, outgoing fibers pass thru here. Midbrain= eye movement control, relay auditory and visual reflex. Pons= relay station between cerebellum and cerebrum. Cn 4= sensory info from scalp, face, mouth, nose. Cn 8 vestibulocochlear= sensory input from ears for hearing and balance. Medulla= helps pons regulate breathing, bp, heart rate, digestion. Cn 11 accessory= somatic control of neck. Cn 12 hypoglossal= somatic control of tongue: reticular formation= nuclei with profuse branching to superior and inferior parts of cns.
