Stretch Reflex. The stretch reflex is one of the simplest reflexes which contract a muscle that is being stretched. The stretch reflex is mediated through a monosynaptic arc and it contributes to the maintenance of steady standing posture and to coordinate muscle movement.
Gastrointestinal (GI) stretch receptors are located throughout the walls of the GI tube from the pharynx to the rectum. They respond to stretch of the tube and subsequently conduct impulses to the CNS over GVA fibers of cranial nerves V (trigeminal), IX, and X as well as certain afferent fibers of the pelvic nerves.
