Document Summary

Cns: overview: terminology in the brain, classifications and structures, three different communication systems, the nervous system, the endocrine system, the immune system. Terminology in the brain: anterior - posterior, superior - inferior, lateral - medial, rostral - caudal, dorsal - ventral, sagittal, coronal, horizontal. Somatic nervous system: sends sensory information to cns for processing, sends messages from cns to muscles to direct motion. Autonomic nervous system: controls activities normally outside of conscious control, two subsystems, sympathetic nervous system, parasympathetic nervous system. Major structures of the brain: cerebral cortex is the most developed part of the brain; makes. Emotions are related to memory, thus they initiate responses which are timely (i. e. fear to induce fast response) The nervous system: structure of the cell, cell body, nucleus, dendrites, axon, terminal buttons. Electrical and chemical events in the nervous system: unilateral direction from cell body down the axon to terminal buttons, action potential goes from -70mv to +40mv.
