1. relating to or denoting a nerve fiber or neuron that carries impulses away from a ganglion, especially in the autonomic nervous system
Usage: medical/anatomical term; commonly used in neuroscience and physiology

Examples

• Postganglionic neurons release neurotransmitters at the target organ.
• The postganglionic fibers of the sympathetic nervous system are typically longer than preganglionic fibers.
• Postganglionic parasympathetic neurons are usually located near or within the target organ.
• Damage to postganglionic nerve fibers can result in loss of autonomic function in that region.
• The postganglionic terminal releases acetylcholine or norepinephrine depending on the division of the autonomic nervous system.
