What is central canal and neural foraminal?

The central canal is a narrow, tube-like structure located within the spinal cord that contains cerebrospinal fluid and runs the length of the spinal column. It plays a critical role in protecting the spinal cord and facilitating the circulation of nutrients and waste. Neural foramina, on the other hand, are openings between the vertebrae that allow spinal nerves and blood vessels to exit and enter the spinal column. These foramina are essential for the proper functioning of the nervous system, as they provide pathways for nerve signals to reach various parts of the body.
