d.Reduced globulin in the blood
e. Increased venous pressure in heart failure

a. False
e. True

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
