Question

Quizplus · Accepted Answer

Melatonin is a hormone produced by the pineal gland in the brain that helps regulate sleep and wake cycles. It is often referred to as the "sleep hormone" as it plays a key role in promoting sleepiness and inducing drowsiness. Epinephrine and norepinephrine are both hormones that are associated with the "fight or flight" response and are not typically involved in promoting sleep. Serotonin is a neurotransmitter that can affect mood and behavior, but also has complex effects on sleep and wakefulness. While it can promote wakefulness in certain contexts, it is not typically described as a sleep-inducing hormone.
