Several hormones like hCG, hPL, oestrogen, progesterone are produced by:
1. | ovary | 2. | placenta |
3. | fallopian tube | 4. | pituitary |
1. | LH and FSH triggers ovulation in ovary |
2. | LH and FSH decrease gradually during the follicular phase |
3. | LH triggers the secretion of androgens from the Leydig cells. |
4. | FSH stimulates the sertoli cells which help in spermiogenesis |
1. | the ovum and sperms are transported simultaneously to the ampullary-isthmic junction of the fallopian tube |
2. | the ovum and sperms are transported simultaneously to the ampullary-isthmic junction of the cervix |
3. | the sperms are transported into the cervix within 48 hrs of the release of the ovum in the uterus |
4. | the sperms are transported into the vagina just after the release of the ovum in the fallopian tube |
Which of the following events is not associated with ovulation in human females?
1. Decrease in Oestradiol
2. Full development of Graafian follicle
3. Release of secondary oocyte
4. LH Surge
In human females, meiosis-II is not completed until?
1. | Puberty | 2. | Fertilization |
3. | Uterine implantation | 4. | Birth |
1. | Increase in oestrogen and progesterone ratio |
2. | Synthesis of prostaglandins |
3. | Release of oxytocin |
4. | Release of prolactin |
Which of the following cells during gametogenesis is normally diploid?
1. | spermatogonia, spermatocyte, spermatozoa, spermatid |
2. | Spermatogonia, spermatozoa, spermatocyte, spermatid |
3. | Spermatogonia, spermatocyte, spermatid, spermatozoa |
4. | Spermatid, spermatocyte, spermatogonia, spermatozoa |
