The central canal helps to transport nutrients to the spinal cord as well as protect it by cushioning the impact of a force when the spine is affected.[2] The central canal below at the ventricular system of the brain, beginning at a region called the obex where the fourth ventricle, a cavity present in the brainstem, narrows.The central canal helps to transport nutrients to the spinal cord as well as protect it by cushioning the impact of a force when the spine is affected.This article incorporates text in the public domain from page 753 of the 20th edition of Gray's Anatomy (1918) Tomsick T, Peak E, Wang L: Fluid-Signal Structures in the Cervical Spinal Cord on MRI: Anterior Median Fissure vs. Central Canal.Fluid-signal structures in the cervical spinal cord on MRI in Chiari patients: Central canal or anterior median fissure?
