Roof of third ventricle.

The third ventricle is one of the four connected ventricles of the ventricular system within the mammalian brain. The roof is separated from the lateral wall by the choroidal fissure which runs in the cleft between the upper part of the thalamus and the fornix. The cavity of the third. The roof of the third ventricle starts anteriorly at the foramen of monro and ends posteriorly in the suprapineal recess.

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 narrow roof of the third ventricle is formed by a thin membrane known as the tela choroidea. The third ventricle receives csf from the lateral ventricles and conveys it to the fourth ventricle which. The third ventricle can be described as having six components.

Running through the third ventricle is the interthalamic adhesion which contains thalamic neurons and fibers that may connect the two thalami. 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 tela chorioidea is a dense network of capillariesthat is surrounded by ependymal cells. 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.
