    anatomy of the spinal cord is very unique. Externally‚ it is initially surrounded by the vertebral column. The vertebral column is divided into the cervical‚ thoracic‚ lumbar‚ sacral‚ and coccygeal regions. These different vertebrae protect the spinal cord from damage and form a type of shell around it. The spinal cord appears as a long‚ thin cord of nerves. The peripheral nerves that extend out to many parts of the body arise from the spinal cords thirty-one segmental pairs of nerves. The cervical

The internal structure of the spinal cord is much simpler and more uniform throughout its many parts than that of the brain. No matter where it is sectioned‚ it gives the same general appearance. The interior of the spinal cord looks grey because it is filled with neurons without having myelin sheath in their axons. There are thirty-one pairs of peripheral spinal nerves connected to the spinal cord. The
