Caption

Illustration of the body clock. Depending on sunlight perceived by the eye, signals are sent to the suprachiasmatic nucleus, where the circadian clock is housed, in the hypothalamus, which controls various biorhythms. The brain secretes melatonin (sleep hormone) which increases as light diminishes.
