The roof of the fourth ventricle has presents a tent like apex at the intersection of it s superior and inferior parts.
Roof of 4th ventricle.
The superior part of the roof is formed by the superior cerebellar peduncles and the superior medullary velum thin sheet of white matter.
Roof the fourth ventricle is formed by all of the following except.
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.
In the upper part it is formed by superior medullary velum white matter between the superior cerebellar peduncles.
Rosette forming glioneuronal tumor 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.
The apex of the tent goes posteriorly into the white core of the cerebellum.
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.
Superior medullary velum c.
Median eminence is seen in the floor of the fourth ventricle.
Fourth ventricle sagittal section of the brain.
Flat floor of fourth ventricle sign.
It corresponds to the ventral surface of the cerebellum.
This apex also known as the fastigium extends into the white core of the cerebellum.
The roof of fourth ventricle is the dorsal surface of the fourth ventricle.
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 composed by a thin sheet of white matter the superior medullary velum that stretches between both superior cerebellar peduncles.
Inferior medullary velum b.
The roof of fourth ventricle is the dorsal surface of the fourth ventricle.
The median part of the superior roof called the superior medullary velum consists of a thin lamina of white matter between the cerebellar peduncles.
It corresponds to the ventral surface of the cerebellum.
