Answered by The Community. Making the world better, one answer at a time. The receptor in the reflex arc of a stretch reflex are 'muscle spindles' which are spindle shaped receptors distributed throughout the belly of the muscle.or example the knee jerk reflex is a monosynaptic reflex: 1. The patellar tendon is stretched. 2. The afferent neuron (which has stretch sensors) send a signal up to the spinal cord. 3. In the spinal cord at the synapse.
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).
