Explain the following phases in the menstrual cycle of a human female:
(1) Menstruation
(2) Follicular phase
(3) Luteal phase
Show Hint
Solution and Explanation
Menstruation: The uterine lining sheds due to a drop in progesterone levels, resulting in menstrual bleeding.
Follicular Phase: FSH stimulates the development of follicles, and estrogen levels increase, thickening the uterine lining.
Luteal Phase: After ovulation, the ruptured follicle forms the corpus luteum, secreting progesterone to maintain the uterine lining for possible implantation.
Top Questions on Menstrual Cycle
- Assertion (A): Corpus luteum secretes the hormone, progesterone. Reason (R): Hormone Progesterone is essential for maintenance of the endometrium.

- Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.
