Deep tendon reflex also known as stretch reflex. When we tap on the tendon of muscle , whole muscle contract transiently due to that intrafusal fibers of muscle also contract transiently. ( intrafusal fibers are sensory organs of muscle ) so it produce action potential on 1a fibers ( afferent fibers) . 1a fibers synapse with Alfa motor neurone . Then alfa motor neurone release acetayl
During examination of deep tendon reflex it is checked the integrity of following component of reflex arc
1. Sensory organ
2. Afferent neurone
3. Central connection
