chordate

present in CNS, pass signals from afferent neurons to efferent neurons
interneurons

efferent
point at which a neuron can transfer an impulse to another cell
synapse
nervous system is divided into two regions
central nervous system and peripheral nervous system
site of processing nerve impulses
