The cerebral aqueduct also known as the aqueduct of Sylviusis a hollow circular channel in the midbrain that connects the third and fourth ventricles . Specificallyit travels through the midline of the dorsal part of the midbrain and is surrounded by periaqueductal (central) grey matter.
Anterior to the aqueduct is the tegmentum and posterior to it are the superior and inferior colliculi (tectum). The aqueduct is continuous with the distal end of the third ventriclejust inferior to the posterior commissure and connects to the fourth ventricle at the junction of the midbrain and pons .
The cerebral aqueduct is an important conduit for cerebrospinal fluid (CSF) in the cerebral ventricular system . It does not contain any CSF producing choroid plexus but does allow CSF to flow from the third to the fourth ventricle.
