Floor Of Lateral Ventricle

Like other ventricles the third ventricle has a cavity an anterior wall a posterior wall a floor a roof and two lateral walls.

Floor of lateral ventricle.

Name the parts of lateral ventricles. The lateral ventricles are the two largest ventricles of the brain and contain cerebrospinal fluid csf. Each cerebral hemisphere contains a lateral ventricle known as the left or right ventricle respectively. 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.

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. The rhomboid lip is a thin sheet of neural tissue located posteriorly to the glossopharyngeal and vagus nerves. Each lateral ventricle is c shaped cavity divided into 4 parts. 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 roof and floor meeting on the lateral aspects. 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. Has a rhomboid shape and formed by the pons and the medulla. The anterior surface of the ventricle contains two protrusions.

Anterior horn in the frontal lobe. It is triangular in cross section and has a roof floor and a medial wall. The obex is also a. Supra optic recess located above the optic chiasm.

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. Floor of the fourth ventricle. This ventricle has a roof and a floor. 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.

It is located in the parietal lobe of cerebrum. The third ventricle is situated in between the right and the left thalamus. Posterior horn in the occipital lobe inferior horn in the temporal horn. From the central part three extensions are given which are as follows.

Infundibular recess located above the optic stalk. The caudal tip of the fourth ventricle where it becomes the central canal is known as the obex.
