The central canal is where the spinal cord travels down the spine. Basically it's the hole in the middle of the spine that the cord travels down through. Then off the spine branch nerve roots which exit the neural foramen on each side; That is the gap where two spinal bones come together towards the posterior and lateral aspect of the vertebrae. You'll find a link below where you can check out the anatomy of the neck in more detail.
The central canal of the spinal cord. The central canal, also known as ependymal canal, is the cerebrospinal fluid-filled space that runs longitudinally through the length of the entire spinal cord.

The central canal of the spinal cord runs down the center of spinal cord from top to bottom and allows cerebrospinal fluid to circulate. The part of the spinal cord directly around the central canal is the gray commissure. This is what connects the two halves of the spinal cord and allows signals to travel between the two sides.

The central canal of the spinal cord is located in the gray commissure and contains cerebrospinal fluid. It is continuous with the ventricular system of the brain, allowing for the circulation and exchange of cerebrospinal fluid between the brain and spinal cord.
Central Canal
The diameter of the central canal in the spinal cord typically ranges from 0.5 to 1 millimeter, although this can vary among individuals. The canal is a narrow, fluid-filled space that runs longitudinally through the center of the spinal cord and contains cerebrospinal fluid. Its primary function is to protect and nourish the spinal cord while allowing for the circulation of this fluid.
No central canal stenosis means that the central canal of the spine, which houses the spinal cord, is of normal width and not narrowed, indicating that there is no compression on the spinal cord. Similarly, the absence of neural foramen stenosis signifies that the openings where spinal nerves exit the spine are also of normal size, allowing for unhindered nerve passage. Together, these findings suggest a healthy spinal structure without signs of nerve compression or spinal cord issues.
The neural canal, also known as the central canal of the spinal cord, functions as a conduit for cerebrospinal fluid (CSF), which cushions and protects the spinal cord. It plays a crucial role in maintaining the homeostasis of the spinal environment, facilitating the exchange of nutrients and waste products. Additionally, it helps in the circulation of CSF throughout the central nervous system, supporting overall brain and spinal cord function.
