Describe the role of preganglionic neurons.
A)They are part of visceral reflex arcs,and most of their activity is a direct reflex response,rather than responses to commands from the hypothalamus.
B)They are part of the visceral motor neurons in peripheral ganglia.
C)They are ganglionic neurons that innervate visceral effectors.
D)They are upper motor neurons whose cell bodies lie within nuclei of the brain or the primary motor cortex.
E)They are motor neurons within the central nervous system that are controlled by reflexes based in the spinal cord or brain.

Question

Quizplus · Accepted Answer

Preganglionic neurons are part of visceral reflex arcs and are responsible for initiating the reflex response. They transmit signals from the central nervous system to the autonomic ganglia, where they synapse with postganglionic neurons that innervate visceral effectors. They are not upper motor neurons or part of the peripheral ganglia themselves.
