The pineal gland, located in the centre of the brain, is about a quarter of an inch in size, reddish-gray, and weighs about one-tenth of a gram 642-972 dumps.

Its location in the center of the brain and presence in other species indicates it is an older part of humanity's evolutionary brain system 70-443 dumps. The pineal gland is present in all lower vertebrae. In other species, like birds, reptiles and frogs, the pineal gland is called the parietal eye or "third-eye" as its functions closely resemble that of an actual eye JN0-522 dumps.
