Biology

The pineal gland, also known as pineal body or epiphysis, is situated centrally in the head. It secretes the hormone melatonin, a hormone produced at night and related to the regulation of the circadian rhythm (or circadian cycle, the wakefulness-sleep cycle). Melatonin possibly regulates many body functions related to the night-day alternation.
