Central nervous system (cns): brain + spinal integrating/command. Peripheral nervous system (pns): nervous + ganglia communication link. Pns division: sensory or afferent (inward, motor or efferent (outward, somatic: interact w/enviro, visceral: w/in body. Motor, interneurons (b/w motor & sensory neurons: unipolar neuron. Dendrites: primary site for receiving signals: ap generated travels down to axon terminal (sends signal to others via neurotrans)
