Question

From the following table, select the option that correctly characterizes various phases of menstrual cycle :

	Menstruation phase	Follicular phase	Luteal phase
(1)	Regeneration of endometrium	High level of progesterone	Developing corpus luteum
(2)	Matured follicle	Regression of corpus luteum	Ovulation
(3)	Menses	Developing corpus luteum	Follicle maturation
(4)	Menses	L.H. Surge	Regeneration of endometrium

• A. (1)
• B. (2)
• C. (3)
• D. (4)

Answer 1

The Correct Option is D

Menstruation phase | Follicular phase | Luteal phase

(A) Regeneration of endometrium | High level of progesterone | Developing corpus luteum

(B) Matured follicle | Regression of corpus luteum | Ovulation

(C) Menses | Developing corpus luteum | Follicle maturation

(D) Menses | L.H. Surge | Regeneration of endometrium

The correct answer is (D) : (4).

Answer 2

The correct answer is: (D) (4).

Let's analyze the phases of the menstrual cycle and match them with the correct descriptions:

• Menstruation phase: This phase involves the shedding of the uterine lining (endometrium), which results in menstrual bleeding. The correct description for this phase is "Menses."
• Follicular phase: During the follicular phase, the ovarian follicles mature, and there is a surge of luteinizing hormone (L.H.), which leads to ovulation. The correct description for this phase is "L.H. Surge."
• Luteal phase: The luteal phase is characterized by the formation of the corpus luteum, which secretes progesterone. The correct description for this phase is "Regeneration of endometrium."

Therefore, the correct option that characterizes various phases of the menstrual cycle is option (4): Menses, L.H. Surge, Regeneration of endometrium.
