Comment: The third ventricle, cerebral aqueduct, and fourth
ventricle developed from the embryonic central canal, responding
to the waves of differential neuronal growth and neural tube folding
that occurred progressively through development. Some regions
(cerebral aqueduct) are narrow and are potential sites of obstruction
of flow of cerebrospinal fluid internally (internal hydrocephalus). The
lateral ventricles expanded in size and location into paired C-shaped
structures, reflecting the growth of the forebrain in a sweeping
C shape from the rostral portion of the neural tube. The lateral
ventricles connect with the third ventricle through the interventricular
foramen of Monro. The choroid plexus is present in the lateral, third,
and fourth ventricles and produces the cerebrospinal fluid, which
flows from rostral to caudal, escaping through the fourth ventricular
apertures, the foramina of Luschka and of Magendie, into the
subarachnoid space.
