Roof Of Third Ventricle

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

Roof of third ventricle.

The roof of the third ventricle starts anteriorly at the foramen of monro and ends posteriorly in the suprapineal recess. 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. The third ventricle receives csf from the lateral ventricles and conveys it to the fourth ventricle which.

The cavity of the third. The floor is formed by the optic chiasma the tuber cinereum and the infundibulum the mamillary bodies. 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 median part lies over the roof of the 3rd ventricle whereas the lateral margins project through the choroid flissure into the lateral ventricle. The tela choroidea is a term for the combination of pia mater and ependyma which are both types of. The third ventricle can be described as having six components. These cells produce cerebrospinal fluid.

Running through the third ventricle is the interthalamic adhesion which contains thalamic neurons and fibers that may connect the two thalami.
