Reflex arcs have evolved as efficient ways of functioning in several emergency situations. reflex [re´fleks] a reflected action or movement; the sum total of any particular automatic response mediated by the nervous system. A reflex is built into the nervous system and does not need the intervention of conscious thought to take effect.

the path taken by stimulus /Impulse during reflex action is called reflex arc steps in reflex action 1.stimulus is detected by receptors and Impulse is carried by sensory neuron into spinal cord 2. Reflex action is a sudden, unconcious and involuntary response of the effectors to a stimulus. Eg :- We suddenly withdraw our hand if we suddenly touch a hot object. In this reflex action, the nerves in the skin (receptor) detects the heat and passes the message through the sensory nerves to the spinal cord. Reflex action is generally controlled by spinal cord. REFLEX ARC :-It is the nerve path involved reflex action for quick responses. A message from the receptor is relayed by sensory nerves to spinal cord, which sends information for responses in a motor nerve to the effector.
