Which area of the brain secretes melatonin as part of the sleep cycle

Question

Quizplus · Accepted Answer

The pineal gland is responsible for secreting melatonin as part of the sleep cycle. The suprachiasmatic nucleus plays a role in regulating the sleep cycle, but does not produce melatonin. The thalamus is involved in sensory processing and the medulla regulates autonomic functions like breathing and heart rate, but neither are directly involved in the sleep cycle or melatonin secretion.
