Final answer:
The visceral efferent fibers of the ANS are accompanied by ganglionic neurons.
Step-by-step explanation:
The visceral efferent fibers of the ANS are accompanied by ganglionic neurons. The efferent branch of the visceral reflex arc is composed of two neurons. The central neuron projects from the spinal cord or brain stem to synapse on the ganglionic neuron, which then projects to the target effector. This process allows for the transmission of signals from the central nervous system to the target organs or tissues.
