GENERAL HISTOLOGY

Detailed explanation-1: -The human central canal extends throughout the spinal cord [1-2]. Derived from the primitive neural tube, the central canal encompasses an internal system of cerebrospinal fluid (CSF) cavities that include the cerebral ventricles, aqueduct of Sylvius, and fourth ventricle [1].

Detailed explanation-2: -The subarachnoid space is a space between your arachnoid mater and pia mater. It’s filled with cerebrospinal fluid.

Detailed explanation-3: -Function: The central canal transports cerebrospinal fluid (CSF), which comes from the brain’s ventricular system. When the spine is injured, the central canal helps to transfer nutrients to the spinal cord while also protecting it by softening the effect of a force.
