Which organ produces the hormone melatonin?

Last Updated: 26 Jun 2026

A reliable solution begins by identifying the organ, tissue, cell, hormone, nutrient, pathogen, or biological process named in the stem and then linking it with its precise function or defining feature. The human body works through coordinated organ systems. Restate the question in your own words, predict the answer before checking the options, and confirm that the explanation and correct-option field both point to Pineal gland.

AThyroid gland

BPituitary gland

CPineal gland

DAdrenal gland

Correct Answer: Pineal glandYour Answer: C

Explanation

Do not confuse an organ that produces a substance with an organ on which that substance acts, or a vector with the organism that causes a disease. Therefore option C, Pineal gland, is factually consistent with the stem, the marked correct index, and the explanation.✅ Correct Answer: C — Pineal gland Melatonin is produced by the Pineal Gland, a small endocrine gland located in the brain. Melatonin regulates the sleep-wake cycle (circadian rhythm). The pineal gland is also called the 'third eye' and is sensitive to light. Thyroid gland — Thyroid gland produces Thyroxine (T3 and T4), not melatonin; regulates metabolism. Pituitary gland — Pituitary gland produces growth hormone, TSH, FSH, LH, prolactin, oxytocin; not melatonin. Adrenal gland — Adrenal gland produces cortisol, adrenaline (epinephrine), aldosterone; not melatonin. 📝 Important Note: Pineal gland = Melatonin (sleep hormone). Pituitary gland = 'Master gland' of the body. Adrenal = Adrenaline (fight or flight). Melatonin supplements are used to treat jet lag and sleep disorders. Key SSC CGL endocrine gland question.

Important Notes

n this record is Pineal gland, corresponding to option C. The answer field, correct index, and both explanations must remain aligned.
Read the complete stem and identify the exact demand: organ, gland, hormone, cell, tissue, nutrient, enzyme, pathogen, vector, deficiency disease, body fluid, or physiological function.
Learn endocrine facts as source–hormone–target–effect–disorder chains. Common errors arise when students confuse the gland producing a hormone with the organ affected by it.
Thyroid gland, Pituitary gland, Adrenal gland are eliminated here because none satisfies the precise requirement of the stem. Practising the reason for each rejection is more reliable than memorising only the correct choice.

FAQ

SSC CGL Human Body FAQs

Common questions and clear answers for this topic.

Which body systems are most important for SSC CGL preparation?

The digestive, circulatory, nervous, and skeletal systems appear most frequently, along with sensory organs and basic endocrine functions.

How many bones are there in the human body, and is this commonly asked?

Yes, the human body has 206 bones, and questions about the largest, smallest, and total bone count appear fairly often.

What kind of blood-related questions come up in SSC CGL?

Questions usually cover blood group compatibility, the role of platelets in clotting, and basic facts about blood pressure and heart function.

Do I need detailed biochemistry knowledge for the human body section?

No, most questions focus on what each organ does and why, rather than the detailed biochemical processes behind it.

How can I retain human body facts more effectively for the exam?

Linking facts to real-life observations, like why pulse is checked at the wrist, makes them easier to recall than memorizing textbook lines.
