The central canal is the cerebrospinal fluid-filled space that runs longitudinally through the length of the entire spinal cord. The central canal is continuous with the ventricular system of the brain. The central canal represents the adult remainder of the central cavity of the neural tube.

It generally occludes (closes off) with age.[1]

The obex connects the central canal to the fourth ventricle.

Clinical significance[edit]

Syringomyelia is a disease caused by the occlusion of the central canal. Occlusions of the central canal typically occur at the lower cervical and upper thoracic levels. This typically damages white matter fibers that cross in anterior white commissure, leading to the loss of temperature, pain, and motor function at the affected levels on contralateral sides.
