Explanation:
Detailed explanation-1: -The withdrawal reflex can occur in either the upper or lower limbs and is a polysynaptic reflex, which means that interneurons mediate the reflex between the afferent (sensory) and efferent (motor) signals. In contrast, the deep tendon reflex is monosynaptic and does not utilize interneurons to transmit information.
Detailed explanation-2: -Interneurons connect sensory and motor neurons in the spinal cord.It receives the stimulus from sensory or afferent neuron and after the processing, it excites motor neuron or efferent neuron which finally reaches the effector organs.
