Roof of the fourth ventricle.

The fourth ventricle has lateral boundaries a roof and a floor. The median part of the superior roof called the superior medullary velum consists of a thin lamina of white matter between the cerebellar peduncles. The roof of ventricle is diamond shaped and can be divided into superior and inferior parts. Roof of the fourth ventricle formed by thin laminae of white matter.

The apex of the tent goes posteriorly into the white core of the cerebellum. The obex is the most caudal tip of the fourth ventricle. The upper portion of the roof is formed by the cerebellum. 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 cavity or fossa of the. It corresponds to the ventral surface of the cerebellum. Roof posterior wall the roof of the 4th ventricle is tent shaped and has upper and lower sloping surfaces. The roof of fourth ventricle is tent shaped and is divided into upper and lower part.

The superior part of. Fourth ventricle lateral walls. The lateral boundaries are formed on each side by the superior cerebellar peduncle the inferior cerebellar peduncle and the cuneate and gracile tubercles. In the upper part it is formed by superior medullary velum white matter between the superior cerebellar peduncles.

The roof of the fourth ventricle is tent shaped and can be divided into upper and lower parts which meet at an apex figs. 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 upper part of the roof is formed by the superior cerebellar peduncles and the superior medullary velum figs. This ventricle has a roof and a floor.

The apex extends into the white core of the cerebellum. 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 fourth ventricle is the dorsal surface of the fourth ventricle. 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.
