The major column of nerve tissue that is connected to the brain and lies within the vertebral canal and from which the spinal nerves emerge. Thirty-one pairs of spinal nerves originate in the spinal cord: 8 cervical , 12 thoracic , 5 lumbar, 5 sacral, and 1 coccygeal. The spinal cord and the brain constitute the central nervous system ( CNS ). The spinal cord consists of nerve fibers that transmit impulses to and from the brain. Like the brain, the spinal cord is covered by three connective-tissue envelopes called the meninges . The space between the outer and middle envelopes is filled with cerebrospinal fluid ( CSF ), a clear colorless fluid that cushions the spinal cord against jarring shock. Also known simply as the cord. See the entire definition of Spinal cord

Spinal cord tumors are rare. They may start in the spinal cord or the spinal cord may be affected by a tumor starting in tissue adjacent to the spinal cord (e.g., bone, nerve or muscle). Signs are usually associated with pain, lameness or paralysis, and vary with which site in the spinal cord is affected. Treatment varies widely and includes surgery, radiation and, rarely, chemotherapy. Outcome also varies widely depending on tumor type, site and degree of spinal cord injury prior to treatment.
