Key points
- The spinal cord lies within the vertebral canal and connects with the brain at the foramen magnum.
- Its segments give rise to 31 pairs of spinal nerves, but spinal cord segments do not always align with the corresponding vertebrae.
- An inner core of grey matter processes information, while surrounding white matter carries signals between spinal levels and the brain.
- Meninges, cerebrospinal fluid and the vertebral column surround and protect the spinal cord.
Definition
Part of the central nervous system located in the vertebral canal continuous with and caudal to the brain; demarcated from brain by plane of foramen magnum. It is composed of an inner core of gray matter in which nerve cells predominate, and an outer layer of white matter in which myelinated nerve fibers predominate, and surrounds the central canal. (CUMBO).
