Question

Quizplus · Accepted Answer

Sensory neurons within intestinal plexuses that travel in the vagus to the CNS are referred to as extrinsic afferents. These neurons are part of the enteric nervous system but are capable of communicating with the CNS via the vagus nerve. Intrinsic afferents, on the other hand, are fully contained within the enteric nervous system and do not communicate with the CNS. Paracrine regulators are signaling molecules that act locally to modulate cell behavior. Myenteric afferents refer specifically to sensory neurons that are located within the myenteric plexus of the enteric nervous system.
