Floor Of 3rd Ventricle

The thalamus is laterally present along the 3rd ventricle.

Floor of 3rd ventricle.

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 floor of the third ventricle is formed by a number of structures including the hypothalamus subthalamus mammilary bodies infundibulum pituitary stalk and the tectum of the midbrain. The hypothalamus is present anteroinferior that is it forms the floor of the 3rd ventricle. Apart from the hypothalamus the mammillary body infundibulum and the tectum of the midbrain also forms the.

Running through the third ventricle is the interthalamic adhesion which contains thalamic. Anterior posterior and two lateral. Like other ventricles the third ventricle has a cavity an anterior wall a posterior wall a floor a roof and two lateral walls. The lateral walls of the third ventricle are formed by the walls of the left and right thalamus.

The third ventricle is one of the four connected ventricles of the ventricular system within the mammalian brain it is a slit like cavity formed in the diencephalon between the two thalami in the midline between the right and left lateral ventricles and is filled with cerebrospinal fluid csf. The diocoel is the 3rd ventricle that is located in the diencephalon which is made up of the thalamus epithalamus and hypothalamus.
