Deep tendon reflex


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
choline at neuromuscular junction at extrafusal fibers . Then acetylcholine act on nicotinc acetylcholine receptors and open iorn channels. Action potential develop at muscle and muscle contract .

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
4.Efferent neurone
5.Effector organ
