COMMENT Pain is carried by the sensory nerves to the central nervous system. From the site it travels up the spinal column to the medulla and through a series of neurones which use Substance P as the neurotransmitter to the sensory cortex. Pain is the method by which a person knows that part of the body is damaged or infected, though the pain is not always felt in the affected part. See synalgia.
