THE REFLEX ARC

When a person steps on a sharp object, the response is immediate. It does not initially involve the brain. This involves the reflex arc which occurs in the spinal cord. The reflex arc consists of the sensory neuron (also called the afferent neuron), which transmits the stimuli of pain to the spinal cord. Within the spinal cord, it relays with the interneuron which decodes the message and sends the response to the muscles of the limbs via the motor neuron (also called efferent neuron) to bring about an action.
