jThe nervous system diagram - Nervous system is split into two categories, the central and peripheral
nervous system. The central nervous system is in the brain and spinal cord. The peripheral nervous
system splits into the somatic and autonomic nervous systems. The somatic nervous system splits into
sensory (afferent) neurons and motor (efferent) neurons. The autonomic nervous system splits into the
sympathetic division and the parasympathetic division.
Neurons - Individual cells in the nervous system that receive, integrate, and transmit information.
Dendrites - Branchlike parts of a neuron that are specialized to receive information.
soma (nerve cell) - where the signals from the dendrites are joined and passed on
myelin sheath - A layer of fatty tissue segmentally encasing the fibers of many neurons; enables vastly
greater transmission speed of neural impulses as the impulse hops from one node to the next.
Axon - the extension of a neuron, ending in branching terminal fibers, through which messages pass to
other neurons or to muscles or glands
axon terminal - The endpoint of a neuron where neurotransmitters are stored
resting potential - The difference in electric charge between the inside and outside of a neuron's cell
membrane
action potential - the change in electrical potential associated with the passage of an impulse along the
membrane of a muscle cell or nerve cell.
absolute refractory period - The minimum length of time after an action potential during which another
action potential cannot begin.
