ANS
parasympathetic division
A division of the (vertebrate) autonomic nervous system whose physiological effects are mostly in opposition to those of the sympathetic nervous system; e.g. it is involved in the slowing of the heart beat and relaxing the muscles.
preganglionic neurons
neurons whose cell bodies lie in the central nervous system and whose efferent fibers terminate in the autonomic ganglia
sympathetic division
A division of the (vertebrate) autonomic nervous system that is chiefly involved in producing an immediate and effective response (e.g. fight-or-flight response) during stress or emergency situations.
postganglionic neurons
neurons whose cell bodies lie in the autonomic ganglia and whose purpose is to relay impulses beyond the ganglia
