Basic clinical descriptions of common patterns of spinal cord involvement are related to essential aspects of spinal cord anatomy. The spinal cord is located inside the vertebral canal, which is formed by the foramina of 7 cervical, 12 thoracic, 5 lumbar, and 5 sacral vertebrae, which together form the spine.
The function of these nerves reflects their location along the spinal cord. 1  Cervical spinal nerves (C1 to C8) emerge from the spinal cord in the neck and control signals to the back of the head, the neck and shoulders, the arms and hands, and the diaphragm.
