Select the incorrect statement.a)Progesterone hormone maintains endom...
Incorrect Statement: hCG hormone maintains corpus luteum in non-pregnant female.
Explanation:
• Corpus luteum is a temporary endocrine gland that develops from the ruptured Graafian follicle after ovulation.
• It secretes progesterone hormone which is essential for the maintenance of the endometrium and pregnancy.
• If fertilization and implantation do not occur, the corpus luteum degenerates and becomes the corpus albicans.
• However, if fertilization occurs, the developing embryo secretes human chorionic gonadotropin (hCG) hormone that maintains the corpus luteum and prevents its degeneration.
• Therefore, the correct statement is that hCG hormone maintains the corpus luteum in pregnant females, not in non-pregnant females.
Summary:
• Progesterone hormone maintains endometrium.
• Granulosa cells of follicle secrete estrogen hormone in the presence of FSH.
• Ruptured Graafian follicle converts into corpus luteum in the presence of LH.
• Incorrect statement: hCG hormone maintains corpus luteum in non-pregnant females.

Select the incorrect statement.a)Progesterone hormone maintains endom...
Incorrect Statement: hCG hormone maintains corpus luteum in non-pregnant female
Explanation:
1. Progesterone hormone maintains endometrium:
Progesterone hormone is produced by the corpus luteum and plays a crucial role in maintaining the endometrium, which is the lining of the uterus. It prepares the uterus for implantation of the fertilized egg and helps in maintaining the pregnancy.
2. Granulosa cells of follicle secrete estrogen hormone in the presence of FSH:
Follicle-stimulating hormone (FSH) is a hormone released by the pituitary gland that stimulates the growth and development of ovarian follicles. The granulosa cells of the follicle secrete estrogen hormone in response to FSH.
3. Ruptured Graafian follicle converts into corpus luteum in the presence of LH:
Luteinizing hormone (LH) is a hormone released by the pituitary gland that triggers ovulation. The LH surge causes the Graafian follicle to rupture and release the mature egg. The remaining follicle cells then transform into the corpus luteum.
4. hCG hormone maintains corpus luteum in non-pregnant female:
Human chorionic gonadotropin (hCG) hormone is produced by the placenta after implantation of the fertilized egg. It maintains the corpus luteum during early pregnancy, which produces progesterone to support the pregnancy. However, in non-pregnant females, the corpus luteum degenerates and is not maintained by hCG.
Therefore, statement B is incorrect as hCG hormone does not maintain corpus luteum in non-pregnant females.
