Central canal of spinal cord

Central Canal of Spinal Cord

The Central Canal of the Spinal Cord is a small cerebrospinal fluid filled channel that runs the length of the spinal cord. It is a part of the ventricular system of the brain and spinal cord.

Anatomy

The central canal is located in the grey matter of the spinal cord, in the anterior median fissure and posterior median sulcus. It is surrounded by the ependymal cells, which are a type of glial cells. These cells are responsible for the production of cerebrospinal fluid.

Function

The central canal serves as a conduit for the flow of cerebrospinal fluid (CSF). The CSF provides buoyancy, protection, and chemical stability to the brain and spinal cord. It also aids in the transport of nutrients, hormones, and waste products between the brain and the bloodstream.

Clinical Significance

Abnormalities or blockages in the central canal can lead to a condition known as syringomyelia, where a cyst or cavity forms within the spinal cord. This can cause a variety of symptoms, including pain, weakness, and stiffness in the back, shoulders, arms, or legs.
