Ventricular System
Definition
A ventricle is an internal cavity of the brain. Within the normal human brain, there is a connecting system of ventricles, commonly referred to as the ventricular system, which is filled with cerebrospinal fluid (CSF). The ventricular system within the brain develops from the cavity of the neural tube in the embryo.
Description
The ventricular system is composed of two lateral ventricles and two midline ventricles, referred to as the third and fourth ventricles. The chambers are connected to allow the flow of cerebrospinal fluid via two interventricular foramen (referred to as the foramen of Monro) and the cerebral aqueduct (referred to as the aqueduct of Sylvius).
The chambers of the ventricular system are lined or covered with ependymal cells and are continuous with the central canal enclosed within the spinal cord. Ependymal cells also line the central canal of the spinal cord.
