Postganglionic fibers in the sympathetic division are adrenergic and use norepinephrine (also called noradrenaline) as a neurotransmitter.

postganglionic fibers in the parasympathetic division are cholinergic and use acetylcholine as a neurotransmitter.

K

In the visceral efferent (lateral gray) column of the spinal cord.

located in the homologous motor nuclei of the cranial nerves.

L

location of postganglionic terminal ending

located distal or posterior to a ganglion.

they lie near or within (respectively) the organs they innervate.

M

Role of adrenal glands

Chromaffin cells of the adrenal medulla are analogous to post-ganglionic neurons; the adrenal medulla develops in tandem with the sympathetic nervous system and acts as a modified sympathetic ganglion.

Overall function

(For Postganglionic terminal endings)

In the sympathetic division, neurons are mostly adrenergic (that is, epinephrine and norepinephrine function as the primary neurotransmitters).
