Match List-I with List-II
| List-I Hormones | List-II Role/functions |
|---|---|
| (A). LH | (I). Causes stronger uterine contractions |
| (B). FSH | (II). Essential for maintenance of the endometrium during menstrual cycle |
| (C). Oxytocin | (III). Acts on Leydig cells and stimulates synthesis and secretion of androgens |
| (D). Progesterone | (IV). Acts on Sertoli cells and stimulates secretion of some factors which help in the process of spermiogenesis |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
(A) LH — this matches (III) Acts on Leydig cells and stimulates synthesis and secretion of androgens. In the male, the pituitary releases LH (luteinising hormone). The Leydig cells lie between the seminiferous tubules, and LH makes them produce androgens such as testosterone.
(B) FSH — this matches (IV) Acts on Sertoli cells and stimulates secretion of some factors which help in the process of spermiogenesis. Sertoli cells sit inside the seminiferous tubules and nourish the developing sperms. FSH acts on these cells, and the factors they release help the spermatids change into sperms.
(C) Oxytocin — this matches (I) Causes stronger uterine contractions. At the end of pregnancy, signals from the foetus and placenta cause oxytocin to be released. Oxytocin makes the uterine muscles contract strongly, and this pushes the baby out during parturition.
(D) Progesterone — this matches (II) Essential for maintenance of the endometrium during menstrual cycle. After ovulation, the corpus luteum secretes large amounts of progesterone. Progesterone keeps the endometrium thick, so it is ready for the implantation of an embryo.
