Melatonin is produced by which gland?

Explanation:
Melatonin is produced by the pineal gland, a small gland nestled in the brain. It makes and releases melatonin mainly at night, helping regulate the sleep–wake cycle. The pineal gland uses serotonin as a precursor, and light exposure suppresses its production through signaling from the eyes to the brain’s clock, while darkness promotes it. Other glands mentioned—pituitary, thyroid, and adrenal—secrete different hormones (such as growth hormone, thyroid hormones, cortisol, adrenaline) and do not produce melatonin.
