CENTRAL NERVOUS SYSTEM
SPINAL CORD – 2
The spinal cord is covered by three layers of meninges. During the dissection of organs of the central nervous system the meninges often stay attached to the bone surfaces that surrounded them (skull bones, vertebrae).
The spinal cord gray matter stains stronger than the white matter because it contains a large number of neuronal and glial cell bodies.
The central or ependymal canal, filled in vivo with cerebro-spinal liquid is seen in the center of the gray matter. The white matter contains mostly nerve fibers disposed longitudinally along the spinal cord.
