GENERAL HISTOLOGY

Detailed explanation-1: -The central canal (also known as spinal foramen or ependymal canal) is the cerebrospinal fluid-filled space that runs through the spinal cord. The central canal lies below and is connected to the ventricular system of the brain, from which it receives cerebrospinal fluid, and shares the same ependymal lining.

Detailed explanation-2: -The space between the arachnoid and pia is called the subarachnoid space and it is filled with the cerebrospinal fluid (CSF).

Detailed explanation-3: -The central canal of the spinal cord contains cerebrospinal fluid (CSF) and is continuous with the ventricles. The central canal is lined with a subtype of glial cell called ependymal cells. These cells are ciliated and function to circulate the cerebrospinal fluid in the central canal, and the brain ventricles.

Detailed explanation-4: -[19] CSF net flow is still generally believed to flow through the ventricular system, initiated at the lateral ventricles. [5] From the lateral ventricles, CSF flows through the left and right foramen of Monro to the third ventricle. Next, it flows through the aqueduct of Sylvius into the fourth ventricle.
