Each spinal nerve is attached to the spinal cord by two roots: a dorsal or posterior sensory root and a ventral or anterior motor root. The fibers of the sensory root carry sensory impulses to the spinal cord—pain, temperature, touch and position sense (proprioception)—from tendons, joints and body surfaces.

Spinal cord nerves transmit information from body organs and external stimuli to the brain and send information from the brain to other areas of the body. The spinal cord is composed of nervous tissue.

A spinal nerve is any of the 31 pairs of nerves that arise from the spinal cord. The spinal nerves correspond to where it emerges and passes through the spinal vertebrae: there are 8 cervical (neck), 12 thoracic (chest), 5 lumbar (lower back), 5 sacral (sacrum bone) and one coccygeal (tailbone) nerve(s).

The axons that link the spinal cord to the muscles and the rest of the body are bundled into 31 pairs of spinal nerves, each pair with a sensory root and a motor root that make connections within the grey matter.

The spinal cord is a cylindrical shaped bundle of nerve fibers that is connected to the brain at the brain stem. The spinal cord runs down the center of the protective spinal column extending from the neck to the lower back.

It can act as a never center and can work without the brain. The spinal cord carries sensory impulses to the brain and motor impulses from the brain. The spinal cord also controls stretch reflexes, bowel and bladder control. Thirty-one pairs of nerves exit from the spinal cord and innervate our body and limbs.

The spinal cord is also organized into segments and named and numbered from top to bottom. Each segment marks where spinal nerves emerge from the cord to connect to specific regions of the body. Locations of spinal cord segments do not correspond exactly to vertebral locations, but they are roughly equivalent. The single coccygeal nerve carries sensory information from the skin of the lower back.

Spinal cord functions:!• Conveys sensory information to brain!• Conveys motor information to PNS!• Reﬂexively integrates sensory and motor information (i.e. decides what to do without asking the brain for help)!Length:!• Extends from medulla to L2 in adults!• 16 to 18 in. long!• About 0.5 in. diameter!
