postganglionaarsete
Postganglionaarsete refers to nerve fibers that originate from a ganglion and extend to an effector organ, such as a muscle or gland. These fibers are part of the autonomic nervous system, which controls involuntary bodily functions. The autonomic nervous system is divided into two main branches: the sympathetic nervous system and the parasympathetic nervous system.
