Spinal cord
A cross section of human lumbar spinal cord has been stained to show areas of white matter (myelinated axons) and grey matter (neuronal cell bodies). The grey matter is subdivided into dorsal and ventral horns. The cell bodies of multipolar neurons are located in the ventral horn. Small segments of dorsal and ventral roots are also present, though their attachment to cord is not visible. 20x

Central canal >
In the center of the cord is the central canal which is continuous with the ventricular system in the brain and contains cerebrospinal fluid. The canal is lined by a simple cuboidal to columnar epithelium composed of ependymal cells.
