Roof Of Fourth Ventricle Anatomy

The fourth ventricle contains choroid plexus along its roof along the tela choroidea which may protrude out the lateral foramina of luschka.

Roof of fourth ventricle anatomy.

In the upper part it is formed by superior medullary velum white matter between the superior cerebellar peduncles. The apex of the tent goes posteriorly into the white core of the cerebellum. Medial eminence is bounded laterally by sulcus limitans. Overlies the vestib ular nuclei hence it is termed vestibular area.

The sidewalls are formed by the veli and cerebellar peduncles. 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 tent shaped and is divided into upper and lower part. 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.

Anatomical terms of neuroanatomy. This apex also known as the fastigium extends into the white core of the cerebellum. The upper portion of the roof is formed by the cerebellum. 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 superior part of the roof is formed by the superior cerebellar peduncles and the superior medullary velum thin sheet of white matter. The obex is the most caudal tip of the fourth ventricle. The roof of fourth ventricle is the dorsal surface of the fourth ventricle. Lateral to sulcus limitans.

The roof of fourth ventricle is the dorsal surface of the fourth ventricle. The roof of the fourth ventricle has presents a tent like apex at the intersection of it s superior and inferior parts. It corresponds to the ventral surface of the cerebellum. Features of the floor of fourth ventricle median sulcus.

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. 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. This ventricle has a roof and a floor.

The roof of ventricle is diamond shaped and can be divided into superior and inferior parts.
