Question

In the autonomic division, the first efferent neurons are referred to as _______ neurons.
A) ganglionic
B) preganglionic
C) postganglionic
D) adrenergic

Accepted Answer

In the autonomic division, the first efferent neurons that transmit signals from the central nervous system to the ganglia are known as preganglionic neurons. These neurons have their cell bodies in the brainstem or spinal cord and their terminals in the autonomic ganglia, where they synapse with postganglionic neurons. Postganglionic neurons then transmit the signal to the target organ. Ganglionic neurons refer to neurons that are located in the ganglia, and adrenergic neurons are a subtype of postganglionic neurons that release norepinephrine as their neurotransmitter.
