Floor Of 3rd Ventricle

The third ventricle in blue is a narrow vertical cleft between the 2 lateral ventricles it possesses a roof a floor and four walls.

Floor of 3rd ventricle.

The hypothalamus is present anteroinferior that is it forms the floor of the 3rd ventricle. Anterior posterior and two lateral. 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 thalamus is laterally present along the 3rd ventricle. Apart from the hypothalamus the mammillary body infundibulum and the tectum of the midbrain also forms the. 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 third ventricle sends messages to and receives messages from the lateral ventricles which are located in front of the third ventricle and the aqueduct of the midbrain which is located.

Like other ventricles the third ventricle has a cavity an anterior wall a posterior wall a floor a roof and two lateral walls. Running through the third ventricle is the interthalamic adhesion which contains thalamic.
