Neural Communication Biological Psychology branch of psychology concerned with the links  between biology and behavior some biological psychologists call themselves  behavioral neuroscientists,  neuropsychologists, behavior geneticists,  physiological psychologist, or biopsychologists Neuron a nerve cell the basic building block of the nervous system

Neural Communication Dendrite the bushy, branching extensions of a neuron that  receive messages and conduct impulses toward the  cell body Axon the extension of a neuron, ending in branching  terminal fibers, through which messages are sent to  other neurons or to muscles or glands Myelin [MY-uh-lin] Sheath   a layer of fatty cells segmentally encasing the fibers of  many neurons makes possible vastly greater transmission speed of  neutral impulses

Neural Communication Action Potential   a neural impulse;  a brief electrical charge that  travels down an axon generated by the movement of positively  charges atoms in and out of channels in the  axon’s membrane Threshold   the level of stimulation required to trigger a  neural impulse
