Roof Of Katersl Ventricles

The right and left lateral ventricles are structures within the brain that contain cerebrospinal fluid a clear watery fluid that provides cushioning for the brain while also helping to circulate.

Roof of katersl ventricles.

Its roof is bound by the tapetum of the corpus callosum and is separated medially from the other lateral ventricle by the septum pellucidum. Immediately above the superior central portion of the tela choroidea is the fornix. The thalami form a major part of the lateral walls of the third ventricle and both thalami connect to form the roof of the third ventricle via a band of gray matter known as the interthalamic connexus. The tela chorioidea is a dense network of capillariesthat is surrounded by ependymal cells.

The body of the lateral ventricle or central part is the part of the ventricle between the anterior horn and the trigone. Since the interventricular foramina are on the lateral edge the corner of the third ventricle itself forms a bulb known as the anterior recess it is also known as the bulb of the ventricle. The body of the lateral ventricle communicates with the atrium posteriorly from the foramina of monro to the corpus callosum and psalterium of the fornix also called the hippocampal commissure. The roof of fourth ventricle is tent shaped and is divided into upper and lower part.

The roof is formed by the trunk of the corpus callosum. The roof of the third ventricleis formed by a part of the choroid plexusknown as the tela chorioidea. The medial wall is formed by the septum pellucidum and by the body of the fornix which is common to two lateral ventricles. The roof of the ventricle comprises choroid plexus forming the inferior central portion of the tela choroidea.

The third ventricle can be described as having six components. Posterior horn in the occipital lobe inferior horn in the temporal horn. The interventricular foramen the roof of the third ventricles and caudal roof of the fourth ventricle. The epithalamus also forms a small portion of the lateral wall and lies above and behind the thalamus.

Each lateral ventricle is c shaped cavity divided into 4 parts. From the central part three extensions are given which are as follows. It is triangular in cross section and has a roof floor and a medial wall. Anterior horn in the frontal lobe.

Outgrowth of the tela choroidea choroid plexus is found in the body atrium and inferior horn of the lateral ventricles. These cells produce cerebrospinal fluid. In the upper part it is formed by superior medullary velum white matter between the superior cerebellar peduncles. A roof a floor and four walls.

It is located in the parietal lobe of cerebrum.
