Roof Of Third Ventricle

The third ventricle receives csf from the lateral ventricles and conveys it to the fourth ventricle which.

Roof of third ventricle.

The cavity of the third. The floor is formed by the optic chiasma the tuber cinereum and the infundibulum the mamillary bodies. The narrow roof of the third ventricle is formed by a thin membrane known as the tela choroidea. The tela chorioidea is a dense network of capillariesthat is surrounded by ependymal cells.

These cells produce cerebrospinal fluid. A roof a floor and four walls. It extent is anteriorly till the interventricular foramen and posteriorly till the transverse fissure gap between the splenium of corpus callosum and roof of 3rd ventricle. The roof of the third ventricle starts anteriorly at the foramen of monro and ends posteriorly in the suprapineal recess.

It is a slit like cavity formed in the diencephalon between the two thalami in the midline between the right and left lateral ventricles and is filled with cerebrospinal fluid. The third ventricle is one of the four connected ventricles of the ventricular system within the mammalian brain. The third ventricle can be described as having six components. The median part lies over the roof of the 3rd ventricle whereas the lateral margins project through the choroid flissure into the lateral ventricle.

The roof of the third ventricleis formed by a part of the choroid plexusknown as the tela chorioidea.
