Q 23 / 30

UPSC CSE Prelims 2000

Match List I (Endocrine glands) with List II (Hormones secreted) and select the correct answer using the codes given below the Lists:

List I List II
I. Gonads A) Insulin
II. Pituitary B) Progesterone
III. Pancreas C) Growth hormones
IV. Adrenal D) Cortisone

EXPLANATION

Correct Option (C)

The correct matching is: I. Gonads - B) Progesterone, II. Pituitary - C) Growth hormones, III. Pancreas - A) Insulin, IV. Adrenal - D) Cortisone.

  • Gonads (testes in males and ovaries in females) produce sex hormones. Progesterone is a key female sex hormone produced by the ovaries.
  • The Pituitary gland, often called the "master gland," secretes various hormones, including Growth Hormone (GH), which regulates growth and metabolism.
  • The Pancreas has both exocrine and endocrine functions. Its endocrine function involves the production of hormones like Insulin and Glucagon, which regulate blood glucose levels.
  • The Adrenal glands, located atop the kidneys, produce several hormones, including corticosteroids like Cortisone, which are involved in stress response and metabolism.

Incorrect Options:

Options A, B, and D present incorrect pairings between the endocrine glands and their respective hormones.

  • Option A incorrectly associates Gonads with Growth hormones, Pituitary with Progesterone, Pancreas with Cortisone, and Adrenal with Insulin.
  • Option B incorrectly associates Pancreas with Cortisone, and Adrenal with Insulin. While the first two pairings are correct, the latter two are incorrect.
  • Option D incorrectly associates Gonads with Growth hormones, Pituitary with Progesterone. While the last two pairings are correct, the first two are incorrect.
