Expert Answer
An involuntary response on stimulation of the peripheral nervous system which requires the involvement of a part of the central nervous system is called reflex action. The afferent neuron receives a signal from a sensory organ. It then transmits the impulse to the spinal cord via the dorsal root. The spinal cord sends the processed signal to the effectors through the efferent neuron forming a reflex arc.
It differs from the normal functions of the brain as brain need sometime to react to anything but reflex are so fast they do not even think.
