Menstrual Cycle, Drawing

The Menstrual Cycle With Periods Of Fecundity. From The Top To The Bottom Ovarian Cycle, Hormonal Cycle And Curve Of Temperature. The Menstrual Cycle Is Divided Into Three Phases The Follicular Phase Or Proliferative, Pre Ovulatory, The Luteal Phase Or Secretory, Post Ovulatory And Menstruation Menses. The Follicular Phase :Inside The Ovary, The Ovarian Follicles, Carrying The Ovocytes, Develop Primordial Follicle, Primary, Secondary And Tertiary. At The Same Time, The Hypothalamic Hormone Gnrh Provokes The Cyclic Secretion Of Two Hypophyseal Hormones, The Gonadotrophins Lh Luteinizing Hormone And Fsh Follicle Stimulating Hormone. The Fsh In Green Enables The Evolution Of The Ovarian Follicles And Assures The Maturation Of A Graafian Follicule By Cycle. This Follicle Secretes Estrogens, Of Which The Rate Will Then Progressively Increase. On The Fourteenth Day Of The Cycle, The Simultaneous Release Of A Strong Dose Of Fsh And Lh In Light Blue Into The Blood Trigger Ovulation A Mature Tertiary Follicle Or Graafian Follicle Ejects The Ovocyte Ii It Contains It Is Ovulation. At The Level Of The Uterus, The Endometrium Is Preparing To Receive A Possible Embryo It Thickens And The Uterine Glands Develop. The Body Temperature Is Stable Between 36. 5 And 37°C In General. The Luteal Phase :Inside The Ovary, Under The Action Of Lh, The Graafian Follicle Emptyied Of Its Content, Or Dehiscent Follicle, Degenerates Into Corpus Luteum ; It Is Follicular Atresia. The Combined Action Of Lh And Fsh Is Responsible For The Secretion Of Estrogen And Progesterone By The Corpus Luteum. The Endometrium Pursues Its Maturation, And The Uterine Glands Secrete Glycogen For The Possible Nutrition Of The Futur Embryo. The Progesterone Acts Indirectly On The Centers Of The Hypothalamus Thermic Regulation, Causing An Increase Of A Few Dozen Of Degrees Of The Body Temperature.
