Answer 6

The menstrual phase is characterized by menstrual flow, which lasts for 3-5 days.

Question 7

What causes menstrual flow during the menstrual phase?

The follicular phase follows the menstrual phase.

Question 11

What occurs during the follicular phase of the menstrual cycle, and what induces these changes in the ovary and uterus?

Answer 11

During the follicular phase, primary follicles in the ovary grow to become fully mature Graafian follicles, and simultaneously, the endometrium of the uterus regenerates through proliferation. These changes are induced by the changes in the levels of pituitary and ovarian hormones.

Question 12

What stimulates follicular development and the secretion of estrogens during the follicular phase?

Answer 12

Follicular development and the secretion of estrogens during the follicular phase are stimulated by changes in the levels of pituitary and ovarian hormones, particularly LH and FSH.

Question 13

When do LH and FSH reach their peak levels in the menstrual cycle?

Answer 13

LH and FSH reach their peak levels in the middle of the cycle, around the 14th day.

Question 14

What event is induced by the rapid secretion of LH during the mid-cycle?

Answer 14

The rapid secretion of LH during the mid-cycle, known as the LH surge, induces the rupture of the Graafian follicle and the release of the ovum, a process called ovulation.

Question 15

What phase follows ovulation (ovulatory phase) in the menstrual cycle?

Answer 15

The luteal phase follows ovulation in the menstrual cycle.

Question 16

What transforms into the corpus luteum during the luteal phase?

Answer 16

The remaining parts of the Graafian follicle transform into the corpus luteum during the luteal phase.

Question 17

What hormone does the corpus luteum secrete in large amounts during the luteal phase?

Answer 17

The corpus luteum secretes large amounts of progesterone during the luteal phase.

Question 18

What is the role of progesterone during the luteal phase?

Answer 18

Progesterone is essential for the maintenance of the endometrium, preparing it for implantation of the fertilized ovum and other events of pregnancy.

Question 19

What happens during pregnancy in relation to the events of the menstrual cycle?

Answer 19

During pregnancy, all events of the menstrual cycle stop, and there is no menstruation.

Question 20

What causes menstruation in the absence of fertilization?

Answer 20

In the absence of fertilization, the degeneration of the corpus luteum causes disintegration of the endometrium, leading to menstruation and marking the beginning of a new cycle.

At what age does menstrual cycles cease in human beings?

Answer 21

Menstrual cycles cease around 50 years of age in human beings, a stage termed menopause.
