The phase of uterine cycle in which degeneration of endometrium occurs is
Correct answer: D. Menstruation
- A. Lueal
- B. Follicular
- C. Ovulation
- D. Menstruation
Explanation
The correct answer is menstruation. During the menstrual phase, the lining of the uterus, known as the endometrium, degenerates and is shed from the body, resulting in menstrual bleeding. This marks the beginning of a new menstrual cycle. The other phases of the uterine cycle, such as the follicular, ovulation, and luteal phases, involve preparation for potential pregnancy, not the shedding of the endometrium.

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.
