A reflex, or reflex action, is an involuntary and nearly instantaneous movement in response to a stimulus. A reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain.Receptor - sense organ in skin, muscle, or other organ. Sensory neuron - carries impulse towards CNS. Interneuron - carries impulse within CNS. Motor neuron - carries impulse away from CNS. (Central nervous system-CNS)
