What is menstrual cycle? Explain it with its diagram and 4 phases.
Answers
The menstrual cycle is complex and controlled by many different glands and the hormones that these glands produce. The four phases of the menstrual cycle are menstruation, the follicular phase, ovulation and the luteal phase. Common menstrual problems include heavy or painful periods and premenstrual syndrome (PMS).
Answer:
The menstrual cycle is a process that adult human women can go through. The menstrual cycle for a woman will repeat every 28 days while they are not pregnant. During this time, the women's ovaries create a mature ovum (egg). Then the woman's body prepares for pregnancy by thickening the walls of the uterus.
The menstrual cycle is divided into four phases, namely:
Menstrual phase: Day 1, uterus lining which is prepared for implantation starts to shed which lasts 3 to 5 days.
Follicular phase: A matured egg follicle releases an egg from one of the ovaries. Also, uterus starts preparation for another pregnancy.
Ovulatory phase: Mid-cycle phase, this is the phase in which ovulation takes place i.e., day 13-17. End of follicular phase along with ovulation period defines the fertilization period.
Luteal phase: Post ovulation phase where the fate of corpus luteum is decided. If fertilization occurs, pregnancy starts. If fertilization doesn’t occur, it marks the onset of another cycle.
