The sensory nerves enter the back of the cord and most go up the to the brain. The motor nerves bring information down from the brain and leave the front of the cord. If severed, all neural activity below that point ceases leaves directly to a motor response without involving higher centers. Monosynaptic reflex input output loop, in which sensory stimulus. Carries information in from the sense organs and down to the skeletal muscles. Peripheral takes information to and from the central nervous system. Carries information to and from the internal organs and glands. When survival is threatened and one needs to fight or run away, this helps prepare one for action.
