The pineal gland is a small gland formation in nature, rounded shape and color grayish, slung beneath the roof of the third ventricle of the brain. It is specifically located to the rear and top of the third cerebral ventricle.
The ventricles are cavities in the brain (nervous system included in the skull).There are:
The two lateral ventricles of each cerebral hemisphere (half a brain)
The third ventricle located in the diencephalon (part of the brain between the two hemispheres) and communicating with the lateral ventricles on each side of the foramen of Monro.
The fourth cavity located in the brainstem (part of the brain between the medulla down, the brain above the cerebellum and back), under the third ventricle between the cerebellum (back) and brainstem (front) . This ventricle communicates with the third ventricle by the aqueduct of Sylvius, and with the surface of the brain by three holes that are the foramen of Magendie and Luschka two holes. Finally, the ventricle communicates with the rest of the spinal cord through a channel from the bottom of the fourth ventricle into the central canal in the center of the spinal cord.
The term epithalamus (from the Greek epi: upon, and thalamos: room) is the dorsal region of the diencephalon which essentially comprises the pineal gland and habenula.The habenula (Latin small belt or band of flesh), also known as stem anterior pineal gland (obsolete term) corresponds to a small projection pair (one on each side of center line) belonging to the epithalamus. It is located in the dorsal and median of the thalamus and joins the epiphysis.
The thalamus is an area of the central nervous system, specifically the brain, consisting of large nuclei of gray matter located on either side of the third ventricle to the front part of the brain. These areas have a role to act as a relay for sensory pathways (nerve carrying sensations). The role of the thalamus is to enable the integration of sensory messages allowed (for) the brain and specifically in the gray matter (cerebral cortex) of it where he carried out the integration of all messages.
