Spinal bones are stacked in a column from the skull to the tailbone It relays sensations to the brain and allows the brain to control movements and function of the internal organs, trunk, and arms and legs. They protect the spinal cord, which runs through an opening called the spinal canal
Some people are born with a small spinal canal. The spinal cord is part of the central nervous system Spinal stenosis is the narrowing of one or more spaces within your spinal canal
The center of the spinal cord is hollow and contains a structure called the central canal, which contains cerebrospinal fluid The spinal cord is also covered by the meninges and enclosed by the neural arches Together, the brain and spinal cord make up the central nervous system. The spinal cord consists of bundles of nerve axons forming pathways that carry incoming and outgoing messages between the brain and the rest of the body
The spinal cord contains nerve cell circuits that control coordinated movements such as walking and swimming, as well as urinating.
