The stretch reflex (myotatic reflex) is a muscle contraction in response to stretching within the muscle. It is a monosynaptic reflex which provides automatic regulation of skeletal muscle length. When a muscle lengthens, the muscle spindle is stretched and its nerve activity increases.
Stretch reflexes are initiated by tapping a tendon, which stretches the muscle the tendon is attached to (the Quadriceps femoris muscle). This stimulates the muscle spindles and causes reflex contraction of the stretched muscle or muscles, which resists further stretching.tretch reflexes are initiated by tapping a tendon, which stretches the muscle the tendon is attached to (the Quadriceps femoris muscle).
