Question

Given below are four statements (a - d) each with one or two blanks. Select the option which correctly fills up the blanks in two statements.
(a) Thymus secretes ______(i) which help in differentiation of ________(ii).
(b) The adrenal medulla secretes _______(i) which stimulates the breakdown of _______(ii) to increase the blood glucose concentration during emergency situations.
(c) The Leydig cells or _______(i) present in the intertubular spaces in testis, produce a group of hormones called _________(ii).
(d) Thyroid gland secretes _______(i) and triiodothyronine. ________(ii) is essential for the normal rate of hormone synthesis in the thyroid.

• A. (a) - (i) melatonin, (ii) T - lymphocytes
  (b) - (i) adrenaline, (ii) fat
• B. (b) - (i) mineralocorticoids, (ii) glycogen
  (c) - (i) interstitial cells, (ii) testosterone
• C. (b) - (i) catecholamine, (ii) glycogen
  (d) - (i) thyroxine, (ii) iodine
• D. (d) - (i) parathyroid hormone, (ii) calcium
  (a) - (i) thymosin, (ii) B - lymphocytes

Answer 1

The correct option is C (b) - (i) catecholamine, (ii) glycogen

(d) - (i) thyroxine, (ii) iodine

(a) The thymus produces and secretes thymosin, a hormone necessary for T cell development and production.

(b) The adrenal medulla secretes catecholamines which stimulate the breakdown of glycogen to increase the blood glucose concentration during emergency situations.

(c) Leydig cells, also known as interstitial cells of Leydig, are found adjacent to the seminiferous tubules in the testicle. They produce testosterone hormone.

(d) The thyroid gland secretes thyroxine and triiodothyronine. Iodine is essential for the normal rate of hormone synthesis in the thyroid gland.

So, the correct option is C.
