Question

Quizplus · Accepted Answer

The suprachiasmatic nucleus, a tiny structure in the brain, is responsible for regulating the body's circadian rhythms, which control the sleep-wake cycle. When it detects bright light, it signals the pineal gland to suppress the release of melatonin, a hormone that is involved in sleep regulation. This allows the body to become more alert and awake during daytime hours.
