What is reflex arc diagram? A reflex arc is a simple nervous pathway which is responsible for the sudden reaction known as the reflex action. The afferent/sensory neurons are present in the receptor organ which receive the stimulus. The motor pathway transmits the signal from motor neurons to the effector organs (muscles and glands etc).
