The spinal cord forms a vital link between the brain and the rest of the body and is part of the central nervous system. Together with the brain it controls bodily functions, including movement and behavior.
The spinal cord is protected by the bones of the spine and is cushioned by a clear fluid called cerebral spinal fluid. Nerves enter and exit the spinal cord at different points to control the various parts of the body including the bladder.
The stretch receptors of the bladder are connected to nerves, which send signals up through the spine to the brain that now is the time to urinate. If it’s convenient for a person to do so, then the brain sends the message back that it’s OK to release urine.
If the spinal cord is damaged, this messaging system will not work, resulting in bladder problems.
