Roof Of Inferior Horn Of Lateral Ventricle

It is a narrow cavity and is bounded by the following structures.

Roof of inferior horn of lateral ventricle.

Here s the interventricular foramen opening into the lateral ventricle. It runs downwards and forwards into the temporal horn from the posterior end of the central part of lateral ventricle. Its roof isformed by the white substance of the cerebral hemisphere. Above and laterally the roof is formed by the stria terminalis medially and tail of caudate nucleus laterally.

As a continuation of the interior side of the ventricular curve the floor of the body of the ventricle becomes the roof of the inferior horn hence the tail of the caudate nucleus forms the lateral edge of the inferior horn s roof until at the extremity of the ventricle the caudate nucleus becomes the amygdala. This strand of vascular tissue in the roof of the ventricle is the choroid plexus which produces cerebrospinal fluid. Rostum of corpus collosum ant wall. Its roofis formed by fibers of the corpus callosum.

The roof and lateral wall are formed by the tapetum. Choroid plexus is also located in the interventricular foramina the channels between the lateral ventricles and the third ventricle. Start studying lateral ventricles. Its roof is formed chiefly by the inferior surface of the tapetum of the corpus callosum but the tail of the caudate nucleus and the stria terminalis also extend forward in the roof of the inferior cornu to its extremity.

Genu of corpus collosum. Theamygdaloid nucleus bulges into the terminal part of the inferior horn. Trunk of corpus collosum flour. The posterior occipital horn of the lateral ventricle extends posteromedially into the occipital lobe and like other parts of the lateral ventricle it has a roof lateral wall and a medial wall.

The tail of the caudate nucleus joins the putamen. It traverses the temporal lobe. The medial wall shows two elevations. In the lateral ventricles it is only present in the inferior horn.

Borders of anterior root. The choroid plexus passes through the foramen and continues into the lateral ventricle. The choroid plexus in the fourth ventricle is beneath the cerebellum. The posterior horn of the lateral ventricle extends backwards into the occipital lobe.

The roof and lateral wall are formed by the tapetum while the medial wall shows two elevations one superior and the other inferior and referred to as the calcar avis. Here s the third ventricle. Learn vocabulary terms and more with flashcards games and other study tools.
