fourth ventricle

The first region is the ventricular zone in the roof of the fourth ventricle.

The obex connects the central canal to the fourth ventricle.

The common location of intracranial ependymoma is the fourth ventricle.

The fourth ventricle is one of the four connected fluid-filled cavities within the human brain.

The fourth ventricle has a characteristic diamond shape in cross-sections of the human brain.

There are 4 subnuclei; they are situated at the floor of the fourth ventricle.

Among the prominent features of the floor of the fourth ventricle are the:

The fourth ventricle has a "roof" dorsally and a "floor" ventrally.

Branches from this artery supply the choroid plexus of the fourth ventricle.

Thus, the central canal opens up at the base of the brain into the lowermost of these, the fourth ventricle.

Without a shunt to relieve the pressure in the fourth ventricle of the brain, hydrocephalus was inevitable.

Specifically, the fourth ventricle originates from the portion of the tube that is present in the developing rhombencephalon.

These fibers then descend through the brain stem periaqueductal gray matter along the base of the fourth ventricle.

The area postrema is a small protuberance found at the inferoposterior limit of the fourth ventricle.

Medulloblastomas usually form in the vicinity of the fourth ventricle, between the brainstem and the cerebellum.

The facility to obtain images in the sagittal plane also enables the relationship of tumours to the fourth ventricle to be readily seen.

There is also cystic dilation of the fourth ventricle, which fills the posterior fossa.

It extends posteriorly from the roof of the fourth ventricle to dorsal neuroepithelial cells.

Receptors on the floor of the fourth ventricle of the brain represent the chemoreceptor trigger zone.

The cerebral aqueduct is a narrow channel in the midbrain, which connects the third and fourth ventricles.

The midbrain in the human being is comparatively small and lies about the narrow passage connecting the third and fourth ventricle.

Rosette-forming glioneuronal tumors of the fourth ventricle.

It communicates with the fourth ventricle posteriorly by the cerebral aqueduct (of Sylvius).

It is located in the roof (dorsal aspect) of the fourth ventricle, lateral to the fastigial nucleus.

Also noticed were Hemorrhages in the gray matter around the third and fourth ventricles and the cerebral aqueduct.
