Which of the following hormones acts on the uterus wall for thickening?
Correct answer: A. Progesterone
- A. Progesterone
- B. Zona pellucida
- C. Follicle stimulating hormone
- D. Oxytocin
Explanation
Progesterone prepares the endometrium for the potential of pregnancy after ovulation. It triggers the lining to thicken to accept a fertilized egg. It also prohibits the muscle contractions in the uterus that would cause the body to reject an egg.In women, FSH helps control the menstrual cycle and stimulates the growth of eggs in the ovaries. FSH levels in women change throughout the menstrual cycle, with the highest levels happening just before an egg is released by the ovary.The two main actions of oxytocin in the body are contraction of the womb (uterus) during childbirth and lactation.Zona pellucida is the thick transparent membrane surrounding a mammalian ovum before implantation.

About Menstrual Cycle
The menstrual cycle covers the coordinated changes in the ovaries and uterus, including menstruation, follicular growth, ovulation and corpus luteum formation. It links follicle-stimulating hormone, luteinizing hormone, oestrogen and progesterone with endometrial changes, and distinguishes the ovarian cycle from the uterine cycle and the hormonal events of pregnancy.
