Several hormones like hCG, hPL, oestrogen, and progesterone are produced by:
1. | ovary | 2. | placenta |
3. | fallopian tube | 4. | pituitary |
Identify the correct statement on ‘inhibin'
1. Is produced by granulosa cells in ovary and inhibits the secretion of FSH
2. Is produced by granulosa cells in ovary and inhibits the secretion of LH
3. Is produced by nurse cells in testes and inhibits the secretion of LH
4. Inhibits the secretion of LH, FSH and prolactin
Select the incorrect statement
1. LH and FSH trigger ovulation in ovary
2. LH and FSH decrease gradually during the follicular phase
3. LH triggers secretion of androgens from the Leydig cells
4. FSH stimulates the Sertoli cells which help in spermiogenesis
Fertilisation in humans is practically feasible only if:
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. |
Ectopic pregnancies are referred to as :
1. | pregnancies with a genetic abnormality |
2. | implantation of the embryo at a site other than the uterus |
3. | implantation of a defective embryo in the uterus |
4. | pregnancies terminated due to hormonal imbalance |
