There are a few anatomical features that can be of importance.
The fallopian tube, the cervix, ovaries, uterus, vagina.
2 Hormonal Regulation
As per normal, control is from the hypothalamus and to the anterior pituitary and into the ovaries.
The gonadotropin releasing hormone from the hypothalamus was released to stimulate anterior pituitary to stimulate LH and FSH generation.
This then stimulates the follicles and the corpus luteum, and it generates steroids and glycoproteins hormones which then stimulates the uterus, the vagina and the cervix.
The negative feedback loops is the feedbacked into the anterior pituitary and the hypothalamus.
The glycoproteins are inhibin A and B.
3 Ovarian cycle
It is a cyclical process.
1) Primordial/Primary Follicle
2) Secondary Follicle
3) Graafian follicle
5) Corpus Luteum
6) Degeneration to corpus albicans and the cycle repeats itself.
3.1 Early follicular Phase Hormonal control
Theca cells from the follicles stimulates the production of inhibit B which inhibits FSH production, it also had paracrine action to increase LH receptors and autocrine action to increase FSH and estrogen receptors.
It decreases FSH and Store LH.
with the production of inhibin B
3.2 Mid-late Phase
Gonadotrophin releasing Hormones stimulates FSH and LH. Creates a surge in estrogen, it also stimulates increase in pulsaltile release of Gonadotrophin Releasing Hormones.
3.3 Ovulation, Luteal Phase
Follicle ruptures due to proteolysis of basal lamina, oocyte and corona radiata is relased into peritoneal cavity. Oocyte drawn into fallopian tube.
It increased in inhibin A secretion, And increased in estrogen and progesterone secretion which creates a negative feedback loop into the anterior pituitary and the hypothalamus.
3.4 Indicators of Ovulation
A. Vaginal Epithelial Cells
B. Body Temperature
C) Cervical Mucus
4 Uterine Cycle
Loss of estrogen and progesterone
Contraction of spiral arteries which reduces the blood tissues and lead to tissue death, it leads to shedding to uterine lining (endometrium) into vagina causing menstrual flow.
4.1.1 Proliferative Phase
Estrogen stimulates the development of uterine lining.
Endometrial layer grows and glands enlarge and epiral arteries elongate, smoth muscle layers thicken.
184.108.40.206 Secretory Phase
Endomentrium is prepared for oocyte implantation. Maintained by progesterone.
Spiral arteries elongate and coil, glands enlarged and secrete glycogen-rich fluids.
Promotes development of secondary sex characteristic. Menstruation, menarche
Stimulate growth of external genitalia.
Subcutaneous fat deposits
Responsible for soft skin
Sodium and water retention
Plasma cholesterol lowering action.
