Roof Of The Fourth Ventricle

The roof of fourth ventricle is the dorsal surface of the fourth ventricle.

Roof of the fourth ventricle.

The fourth ventricle contains choroid plexus along its roof along the tela choroidea which may protrude out the lateral foramina of luschka. In the upper part it is formed by superior medullary velum white matter between the superior cerebellar peduncles. The roof is composed of the cerebellum located at the back of the brain and the floor is formed by the rhomboid fossa a depression in the brainstem. The roof of ventricle is diamond shaped and can be divided into superior and inferior parts.

The apex of the tent goes posteriorly into the white core of the cerebellum. The roof of the fourth ventricle is tent shaped and can be divided into upper and lower parts which meet at an apex figs. Roof of the fourth ventricle formed by thin laminae of white matter. The apex extends into the white core of the cerebellum.

Rosette forming glioneuronal tumor of the fourth ventricle. The fourth ventricle has a roof at its upper posterior surface and a floor at its lower anterior surface and side walls formed by the cerebellar peduncles nerve bundles joining the structure on the posterior side of the ventricle to the structures on the anterior side. The roof of the fourth ventricle has presents a tent like apex at the intersection of it s superior and inferior. The roof of fourth ventricle is tent shaped and is divided into upper and lower part.

Fourth ventricle lateral walls. Roof posterior wall the roof of the 4th ventricle is tent shaped and has upper and lower sloping surfaces. The upper part of the roof is formed by the superior cerebellar peduncles and the superior medullary velum figs. The lateral boundaries are formed on each side by the superior cerebellar peduncle the inferior cerebellar peduncle and the cuneate and gracile tubercles.

The upper portion of the roof is formed by the cerebellum. It corresponds to the ventral surface of the cerebellum. The obex is the most caudal tip of the fourth ventricle. This ventricle has a roof and a floor.

The roof of the fourth ventricle is tent shaped rising to an apex called the fastigium that divides the superior roof from the inferior roof. The upper part of the roof is composed by a thin sheet of white matter the superior medullary velum that stretches between both superior cerebellar peduncles. The superior part of. The median part of the superior roof called the superior medullary velum consists of a thin lamina of white matter between the cerebellar peduncles.
