Introduction:

Menstrual cycle is a cycle that takes place in females. It is a cycle or a series of events in which there are hormonal changes in females in ovary and in the uterine wall. In this cycle there is formation of a mature egg in the ovary of females which due to hormonal influence undergoes a series of changes and if the fertilization of the egg takes place then there is formation of zygote and henceforth there is formation of a neonate.

Explanation of Solution

This graph is about the various phases of the menstrual cycle and the hormones related to them. In a menstrual cycle there are three phases. Here in the graph the first phase that is P shows menstruation or the menstrual phase which occurs from first to fifth day, the hormone related to this phase is labeled as A which is FSH. It is secreted by the anterior lobe of the pituitary gland.

Second phase is the follicular phase which is marked as Q. It starts from the first day and continues till 13^th day, the hormone that is related to this phase is labeled as B which is estrogen. It is secreted by the granulose cells of ovarian follicle and by corpus luteum.

The third phase is the ovarian phase which is marked as R. It occurs at the fourteenth day, the hormone that is related to this phase is labeled as C which is LH. This hormone is secreted by the anterior lobe of pituitary gland.

And the last phase is the development of corpus luteum, which is marked as S. It occurs after the fifteenth day. The hormone that is related to it is progesterone which is marked as D. it is secreted by the corpus luteum which is the ruptured covering of the matured egg upon stimulation by the FSH hormone after ovulation.

Before pregnancy the cycle as mentioned in the diagram goes uninterrupted but after pregnancy with the secretion of the human chorionic gonadotropin hormone which is secreted by the placenta, the entire hormonal cycle changes.

With the secretion of human chorionic gonadotropin hormone, with the onset of pregnancy the estrogen and the progesterone levels remain high and the other hormones levels becomes low.

Conclusion

The menstrual cycle in females is responsible for the production and the discharge of the egg formed by the ovaries in females.
