The stalk of the gland forms part of the posterior superior wall of the third ventricle and lies in between the posterior commissure and the more dorsal habenular commissure.

Detailed explanation-4: -The pineal gland in humans is a small (100-150 mg), highly vascularized, and a secretory neuroendocrine organ (1). It is located in the mid-line of the brain, outside the blood-brain barrier and attached to the roof of the third ventricle by a short stalk.

Detailed explanation-5: -The pineal gland projects posteriorly from the wall of the third ventricle above the quadrigeminal plate, resting in the groove between the two superior colliculi. The gland has several functions, the most important of which is maintaining the body’s circadian rhythm and regulating the sleep-wake cycle.
