Floor Of Lateral Ventricle

This ventricle has a roof and a floor.

Floor of lateral ventricle. 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. Supra optic recess located above the optic chiasm. The rhomboid lip is a thin sheet of neural tissue located posteriorly to the glossopharyngeal and vagus nerves. Posterior horn in the occipital lobe inferior horn in the temporal horn.

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 tela choroidea forms the floor of both parts of the lateral recess. 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. The lateral ventricles are connected to the third ventricle by the foramen of monro.

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 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. Name the parts of lateral ventricles. Anterior horn in the frontal lobe.

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. It is triangular in cross section and has a roof floor and a medial wall. The obex is also a. Has a rhomboid shape and formed by the pons and the medulla.

The caudal tip of the fourth ventricle where it becomes the central canal is known as the obex. Infundibular recess located above the optic stalk. 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. Like other ventricles the third ventricle has a cavity an anterior wall a posterior wall a floor a roof and two lateral walls.

The roof and floor meeting on the lateral aspects. Floor of the fourth ventricle. Each lateral ventricle is c shaped cavity divided into 4 parts. From the central part three extensions are given which are as follows.

Each cerebral hemisphere contains a lateral ventricle known as the left or right ventricle respectively. The third ventricle is situated in between the right and the left thalamus.
