Question

The central canal inside the spinal cord in the upper part, is continuous with the ______.

• A. Fourth ventricle
• B. Third ventricle
• C. Lateral ventricles
• D. Foramen magnum

Answer 1

The correct option is A

Fourth ventricle

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 is continuous with the ventricular system of the brain. The fourth ventricle narrows at a region called the obex to become the central canal of the spinal cord.
