Making the world better, one answer at a time. The receptor in the reflex arc of a stretch reflex are 'muscle spindles' which are spindle shaped receptors distributed throughout the belly of the muscle.
A withdrawal reflex, also known as a flexor reflex, is a polysynaptic reflex arc. Sensory and motor neurons are part of this reflex, as are association neurons. Pain is the most obvious stimuli that initiates the flexor reflex, as painful stimuli sets the whole reflex into action. reflex arc is in fact the simplest and most primitive nerve pathway in the human body. A reflex arc is designed to administer unconscious automatic actions which are determined to be protective in nature to keep a body in homeostasis.
