The pineal gland is best known for the secretion of the hormone melatonin, which is released into the blood and possibly also into the brain fluid, known as cerebrospinal fluid. Melatonin secreted by the pineal gland is an important part of the body's circadian timing system and can synchronise daily rhythms (see the articles onjet lagandcircadian rhythm sleep disorders).
