Floor Of Lateral Ventricle

The caudal tip of the fourth ventricle where it becomes the central canal is known as the obex.

Floor of lateral ventricle.

Posterior horn in the occipital lobe inferior horn in the temporal horn. This ventricle has a roof and a floor. 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. Name the parts of lateral ventricles.

Infundibular recess located above the optic stalk. Like other ventricles the third ventricle has a cavity an anterior wall a posterior wall a floor a roof and two lateral walls. Along with the structures known as the third ventricle and the fourth ventricle the lateral ventricles are part of the body s ventricular system the ventricular system acts as a continuation of. Supra optic recess located above the optic chiasm.

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 lateral ventricles are the two largest ventricles of the brain and contain cerebrospinal fluid csf. The lateral ventricles are connected to the third ventricle by the foramen of monro. Anterior horn in the frontal lobe.

From the central part three extensions are given which are as follows. Has a rhomboid shape and formed by the pons and the medulla. The obex is also a. It is triangular in cross section and has a roof floor and a medial wall.

Floor of the fourth ventricle. The anterior surface of the ventricle contains two protrusions. Each cerebral hemisphere contains a lateral ventricle known as the left or right ventricle respectively. The central part of the lateral ventricle is elongated anteroposteriorly anteriorly it becomes continuous with the anterior horn at the level of the interventricular foramen posteriorly the body reaches the splenium of the corpus callosum.

Each lateral ventricle resembles a c shaped cavity that begins at an inferior horn in the temporal lobe travels through a body in the parietal lobe and frontal lobe and ultimately. The roof and floor meeting on the lateral aspects. Floor and roof the floor is formed by the optic chiasma the tuber cinereum and the infundibulum the mamillary bodies the posterior perforated substance and the tegmentum of the midbrain. The third ventricle is situated in between the right and the left thalamus.

The third ventricle is a narrow cavity located between the two hemispheres of the diencephalon of the forebrain the third ventricle is part of a network of linked cavities cerebral ventricles in the brain that extend to form the central canal of the spinal cord the cerebral ventricles consist of the lateral ventricles third ventricle and fourth ventricle. The tela choroidea forms the floor of both parts of the lateral recess.
