A narrow conduit (tube), between the third and the fourth ventricles; located in the midbrain. CSF moves from the third ventricle through the cerebral aqueduct to the fourth ventricle.
a canal connecting the third and fourth ventricles
The narrow channel of the midbrain that joins the third and fourth ventricles of the brain. Cerebrospinal fluid travels through this channel into the fourth ventricle. It joins the third and fourth ventricle of the brain.
Part of the ventricular system that connects the third and fourth ventricles.
The mesencephalic duct, also known as the aqueduct of Sylvius or the cerebral aqueduct, contains cerebrospinal fluid (CSF), is within the mesencephalon (or midbrain) and connects the third ventricle in the diencephalon to the fourth ventricle, which is between the pons and cerebellum.
