The pineal gland is a small, pea-sized organ in the brain that produces a hormone called melatonin. Melatonin helps regulate sleep patterns and the body's circadian rhythm. The word 'pineal' is often used to describe anything related to the pineal gland or its hormone, such as pineal tumors or pineal gland dysfunction. It is mostly used in the medical context.
