본문내용

In the center of the cord locate a small,clear space which is known as the central canal. This canal is filled with cerebrospinal fluid and runs the length of the spinal cord. At its anterior end it is continuous with the fourth ventricle of the brain. In viewing the cross section you should note a butterfly shaped area of gray matter filling much of the central area. The gray matter is named because it appears gray in fresh tissue due to the presence of numerous cell bodies. The peripheral area of the section is made up of the more uniformly colored white matter. In the cross section, the white matter has a granular appearance. This is because the white matter consists largely of axons which communicate up and down the spinal cord. They appear as small, round dots in transverse section. In your section, you should also see parts of dorsal and ventral roots as well as the dorsal root ganglion which will help you to orient the section.
