Roof Of Fourth Ventricle Define

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

Roof of fourth ventricle define.

Roof of fourth ventricle formed in its upper part by the superior medullary velum stretching between the two brachia conjunctiva superior cerebellar peduncles and in its lower part by the inferior medullary velum composed of the choroid membrane and choroid plexus of the fourth ventricle. There is a deficiency in the lower portion of the roof called the median aperture foramen of magendie. A large opening in the midline of the roof of the posterior interior section of the fourth ventricle. This is lined by ependymal.

Roof of fourth ventricle formed in its upper part by the superior medullary velum stretching between the two brachia conjunctiva superior cerebellar peduncles in its lower part by the inferior medullary velum composed of the choroid membrane and choroid plexus 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. Lateral vestibular nucleus nci thesaurus. Foramen of magendie nci thesaurus one of the four vestibular nuclei situated on the floor and lateral wall of the fourth ventricle that receives inputs from the vestibular nerve.

Roof of fourth ventricle. The roof of ventricle is diamond shaped and can be divided into superior and inferior parts. The posterior boundary or roof of the fourth ventricle is very thin and concealed by the cerebellum. It consists of white matter referred to as the superior and inferior medullary vela.
