Respuesta :

The Central Nervous System (CNS) consists of the brain and the spinal cord. The spinal cord is the continuation of the brain which lies protected within the bones of the spine.

The Peripheral Nervous System (PNS) consists of 12 cranial nerves, and 31 pairs of spinal nerves.  The PNS acts as the system of electrical wires that allows for communication between the CNS and the body’s muscles and sensory receptors. They also control the automatic functions of the bowel, bladder, respiratory (breathing), and heart function.

  Each spinal nerve is attached to the spinal cord by two roots: a dorsal (or posterior) root which relays sensory information and a ventral (or anterior) root which relays motor information. Therefore, once the two roots come together to form the spinal nerve, the nerve carries a combination of both sensory and motor information.
