A reflex contraction of a muscle in response to sudden stretching, controlled by a reflex arc involving just one sensory nerve fibre from a muscle spindle and one motor neuron. Numerous stretch reflexes help to maintain posture against gravitational and other forces, and deep tendon reflexes are special examples of stretch reflexes. Also called a myostatic reflex. See also monosynaptic reflex, reflex.
