What is "central canal"?
The central canal, also known as the ependymal canal, is a small, fluid-filled channel that runs longitudinally through the center of the spinal cord. It is lined with ependymal cells and contains cerebrospinal fluid, which provides cushioning and support for the delicate neural tissues. The central canal is responsible for the circulation of cerebrospinal fluid within the spinal cord, facilitating the exchange of nutrients and waste products. Additionally, it plays a role in maintaining the overall hydrostatic pressure and homeostasis of the spinal cord environment.
Examples
