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.
A stretch reflex, also referred to as a deep tendon reflex or myotatic stretch reflex, is a physical response to the extension of a muscle. In essence, it is a process that causes a contraction, thereby stopping a stretch.
