Different stages of menstrual cycle

Answer 1

Menstrual cycle is a cycle of physiological changes that can occur in fertile females. Overt menstruation where the blood flow from the uterus through the vagina occurs primarily in humans and close evolutionary relatives such as chimpanzees. It mainly occurs due to chage in hormone level in the body. If a girl has menses it means she is ready to become mother after conception.

Most fertile days to get pregnant are 12-14 days.

Menstrual cycle is of 28-35d ays depending upon women. Lets take it is of 28 days: from 1-5 days it is called as bleeding phase when blood and shedding of endometrium walls of uterus come out from urethra due to decreased level of progestrone hormone Pain may occur during this period due to release of prostaglandins hormone. 5-14 days it is called as preparatory phase as uterus reforms its endometrium due to increased level of LH & FSH hormone. On 14th day ovulation occurs i.e. ovum is released from the ovary in uterus then 14-28 days uterus walls prepares themselves to get zygote if fertilzation occurs. This period is called luteal phase and if no fertilization occurs ovum is shed out in bleeding phase, and the cycle continues.

Answer 2

The Ova is released from the Ovary and let into the Fallopian tube. If the Ova isn't fertilized it carries on through it's journey into the uterus where it gets stuck onto the side of the uterus and in a few days it becomes waste and exits through the cervix out the vagina.

Generally the start of the menstrual cycle is considered to be the period, where the lining of the uterus leaves the vagina. This complex cycle is controlled by hormones, where Follicle stimulating hormone (FSH) develops the follicle, this hormone is released into the blood by the pituitary gland in the brain. The developing follicle releases estrogen which causes the lining of the uterus to thicken, and also inhibits the release of FSH so no more follicles are mature (partly why generally only one ovum is released per month). A surge of estrogen causes a surge in FSH and another hormone called luteinizing hormone (LH), this hormone causes ovulation, where the oocyte (or ovum) is released, leaving behind the follicle it developed in, LH causes this to be developed into the corpus luteum. This corpus luteum releases the final hormone called progesterone, which maintains the uterus lining (or endometrium) ready for fertilization to occur, if it doesn't, then the corpus luteum dies, progesterone secretion stops and therefore the uterus lining is no longer maintained, and so the cycle starts again.

A menstrual cycle can last for 28 days to 45 days, during this cycle a woman could have bloating, cramps, mood swings, and a period. A period is when the ovaries produce an egg which goes through the fallopian tubes into the uterus, if the egg is not fertilized by a sperm the egg and the vagina sheds a layer of blood and tissue.

Answer 3

There are four major stages in the menstrual cycle:

1. Menstrual phase: uterine lining sheds.
2. Follicular phase: eggs mature in the ovary.
3. Ovulation phase: eggs released from the ovary.
4. Luteal phase: uterine lining builds-up.
