Roof Of Fourth Ventricle Anatomy

It corresponds to the ventral surface of the cerebellum.

Roof of fourth ventricle anatomy.

The sidewalls are formed by the veli and cerebellar peduncles. This apex also known as the fastigium extends into the white core of the cerebellum. The roof of ventricle is diamond shaped and can be divided into superior and inferior parts. In the upper part it is formed by superior medullary velum white matter between the superior cerebellar peduncles.

The roof of the fourth ventricle has presents a tent like apex at the intersection of it s superior and inferior parts. Roof posterior wall the roof of the 4th ventricle is tent shaped and has upper and lower sloping surfaces. Superior fovea upper end of sulcus limitans widens into a triangular depression. It rises up and backwards forming two walls called the roof of the 4th ventricle which converge into a summit located in the anterior part of the cerebellar vermis fig.

The roof of fourth ventricle is tent shaped and is divided into upper and lower part. It is widest at the level of the pontomedullary junction. Anatomical terms of neuroanatomy. Features of the floor of fourth ventricle median sulcus.

The fourth ventricle contains choroid plexus along its roof along the tela choroidea which may protrude out the lateral foramina of luschka. The upper portion of the roof is formed by the cerebellum. The obex is the most caudal tip of the fourth ventricle. The roof of fourth ventricle is the dorsal surface of the fourth ventricle.

The 4th ventricle is in the form of a spread and irregular cone whose base or floor is supported on the dorsal side of the brainstem. 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. It corresponds to the ventral surface of the cerebellum. The apex of the tent goes posteriorly into the white core of 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 superior part of the roof is formed by the superior cerebellar peduncles and the superior medullary velum thin sheet of white matter. The roof of fourth ventricle is the dorsal surface of the fourth ventricle. Lateral to sulcus limitans.

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.
