Explanation:
Detailed explanation-1: -TRANSCRIPT: The withdrawal reflex is an automatic response enacted to withdraw a limb from a painful stimulus. If, for example, you were to touch a hot stove or step on a tack, the withdrawal reflex would cause you to pull your arm or leg away from the painful stimulus without having to consciously plan to do so.
Detailed explanation-2: -The withdrawal reflex is a polysynaptic reflex, as it uses neurons called interneurons to pass signals from sensory to motor neurons, creating multiple synaptic connections. The reflex begins when a painful stimulus is detected by receptors called nociceptors, which are specialized to detect noxious stimuli.
