The organs of our body (viscera), such as the heart, intestines and stomach, are regulated by a branch of the nervous system known as the autonomic nervous system. The autonomic nervous system is part of the peripheral nervous system and controls the function of many muscles, glands and organs within the body.
1 The sympathetic division of the autonomic system activates the body to fight or flight through adrenergic effects. 2  The parasympathetic division often exerts antagonistic actions through cholinergic effects. 3  All preganglionic autonomic nerve fibers are cholinergic (use ACh as a neurotransmitter). Preganglionic parasympathetic fibers originate in the brain and in the spinal cord. 2  Preganglionic parasympathetic fibers contribute to cranial nerves III, VII, IX, and X. 3  The long preganglionic fibers of the vagus (X) nerve synapse in terminal ganglia located next to or within the innervated organ.
