<P> Throughout the cervical and thoracic regions the central canal is situated in the anterior third of the spinal cord ; in the lumbar enlargement it is near the middle , and in the conus medullaris it approaches the posterior surface . It is filled with cerebrospinal fluid , and lined by ciliated , columnar epithelium , outside of which is an encircling band of gelatinous substance , the substantia gelatinosa centralis ( or central gelatinous substance of spinal cord ) . This gelatinous substance consists mainly of neuroglia , but contains a few nerve cells and fibers ; it is traversed by processes from the deep ends of the columnar ciliated cells which line the central canal . </P>
