Anatomical terms of neuroanatomy

The cerebral aqueduct (aque ductus mesencephali, mesencephalic duct, sylvian aqueduct or aqueduct of Sylvius) is a narrow 15 mm conduit for

gray matter called the periaqueductal gray, or central gray. It was first named after Franciscus Sylvius
.

Structure

Development

The cerebral aqueduct, as other parts of the ventricular system of the brain, develops from the central canal of the neural tube, and it originates from the portion of the neural tube that is present in the developing mesencephalon, hence the name "mesencephalic duct."[2]

Function

The cerebral aqueduct acts like a canal that passes through the midbrain. It connects the third ventricle with the fourth ventricle so that cerebrospinal fluid (CSF) moves between the cerebral ventricles and the canal connecting these ventricles.[1]

Clinical significance

pinealoblastoma), or through cyclical gliosis secondary to an initial partial obstruction.[1]

History

The cerebral aqueduct was first named after Franciscus Sylvius.[3]
