The Menstrual Cycle known as a woman’s period is the physical bodily actions that take place monthly when woman reproductive system produces eggs in addition to fertilization. The Menstrual cycle splits into halves and contains the ovaries, hypothalamus and lastly the pituitary (Freudenrich 2015). This cycle lasts between 21 to 45 days ovulation depending on the age and menopause development. The female body matures in body penetration of the lining in the womb. The hemoglobin streams through the womb starting from the cervix all the way through the vulva.
The Menstrual Cycle is important because it produces bodily hormones for the body to keep it in good health, normal and strong. Not only does the cycle produce hormones but it also helps
The follicular phase (Days 6 through 14) is the outcome of the ovarian cycle, and the menstrual preovulatory phase. During this phase the ovaries glands are maturing. In the follicular phase the process of the cells, glands and organs of the luteinizing hormone (LH), the follicle stimulating hormone (FSH) and oestrogen enables the maturation of the cavities, glands and sacs in the ovaries positioned through the womb to produce egg fertilization (Freudenrich 2014). In the middle of the cycle the egg that’s fertilized sends an cue or indication through the Luteinizing hormone and the Follicle stimulating hormone signaling the eggs produced in the female reproductive system to release the fertilize eggs. In which this is where the eggs travels through the fallopian tube and where it has a chance of merging with sperm in which this is the act of
The luteal phase becomes actives before and after the menstrual cycle. When a fertilized egg is released from the ovaries the female menstrual cycle begins then that’s when the inner portion of the female womb is more likely to become dense and broad in preparation of gestation (Freudenrich 2015).
In addition to the menstrual cycle there are a few diseases that affects the cycle in human females. One of the various diseases is menorrhagia, which is the excessive blood flow in the system. Hormone inequality and Pregnancy complexity can cause menorrhagia disease. Hormone inequality is the expansion of the endometrium scattering by the heaviness of bleeding (Mayo Clinic 2014). In the rare case of pregnancy complexity, anytime a woman experiences large amounts of bleeding or delayed period the result is more than likely the phases of a miscarriage.
In conclusion the menstrual cycle can be impacted by the daily environment in human females. Analysis has shown that the menstrual cycle impacts females’ everyday day life such as in the work place and also devouring of caffeine drinking and smoking
This cycle tends to last anywhere from five to seven years and is shorter for hair on the eyebrows, armpits and pubic area. Inside the bulb of each hair is a component called the dermal papilla which controls the hair growth while the matrix of the hair, which contains a large amount of epidermal cells that rapidly divide, is responsible for the length of the hair. Next is the catagen phase which is characterized as a transition period between the anagen and telogen phases. At this time the hair bulbs are pushed out in order to become keratinized and the hair appears short and thick. This phase tends to only last between two and three weeks. During the telogen phase, no new cell division occurs, which means that the length of the hair remains the same. This pause allows the dermal papilla to fill up the matrix with new cells in preparation for the anagen phase to begin again. This phase can last between three and nine months. After this phase, the anagen phase begins again. The telogen phase is periodically followed by shedding, or exogen. This leads to the last phase, the exogen phase. This phase is characterized by the shedding of hair. Each day about one hundred hairs are shed from the average individual’s scalp. The shaft of the hair is shed and the follicle remains. Despite the fat that the exogen phase usually follows the telogen phase, there are exceptions when it does not, resulting in hair follicles needing to go
FSH and LH start development of the follicle. After around 12 days the level of estrogen peaks. The high estrogen level has a positive feedback loop, which fuels the release of FSH and LH. The increase in LH causes the follicle to rupture, and the follicle cells that remain grow into the corpus luteum. When the follicle is mature, progesterone levels rise to stimulate the growth of the uterine lining in preparation for a fertilised egg. Progesterone has a negative feedback loop with the hypothalamus that inhibits GnRH, as well as FSH and LH. If there is no fertilisation, the levels of progesterone drop. This causes corpus luteum starts to shrink, endometrium breakdown, and menstruation begins. (The Ovarian And Menstrual Cycle 2013) (Hormones of the Reproductive System

should go through and if it doesn’t then the women has an irregular cycle. This process the movement of an egg to a fertilizing position, developing a lining in the uterus, then the shedding of that lining when the egg doesn’t become fertilized.
Although oestrogen is present in both male and females, it is found to be significantly higher in women and is involved in controlling the menstrual cycle. As does progesterone, oestrogen also affects all aspects of the pregnancy and is particularly important in maintaining the health of the genital track, the reproductive organs and the breasts.

The dominant assumptions of the cycles that are present in both sexes, are that as followed, men are to be strong showing no emotion, and women are to be weak and over emotional. This is why such an occurrence is not widely talked about between men. The stigma that follows women is such a horrible thing. It seems that society put out research more on women than men in regards to the “cycle.” It makes it easier for the world to blame things on a women when you can say its because she is on her period. This keeps oppression on women and only makes them become more
The egg is covered with a hard protein shell that called a zona. No sperm is just strong enough to break this shell, so the sperm has to introduce itself properly first. Once the sperm goes through and completes all of the challenges. The egg and sperm take over and begin developing a baby. The development of a baby goes through three trimesters before the parents get to meet their “Life’s Greatest

The female reproductive systems is made of 9 parts. The sex cell for the female reproductive system is called the egg or ovum. The egg spends it’s dormant life in the ovaries until it is released. The egg has 23 chromosomes within it. The ovaries have two goals: to create and house eggs and the release the female sex hormones, estrogen and progesterone. The fallopian tubes are what the egg travels through to reach the uterus. Fallopian tubes contain tiny hair-like structures called cilia; the cilia allows for mobility of the egg. The fallopian tube is roughly the size of 2 hairs, and is the site of where ectopic pregnancies happen. The process of the egg getting released from the ovaries through the fallopian tubes is called ovulation. Ovulation happens on the 14th day of the menstruation cycle The uterus is where the egg goes to after it travels through the fallopian tubes. The developing baby is held and nourished in the uterus. When the uterus is empty, it’s roughly the size of a fist but expands one an embryo starts to develop. The endometrium is the lining of the uterine wall. It’s used to protect the fetus. When the egg isn’t fertilized, menstruation ha...
Depression is most common in women. The rates are twice as high as they are in men. According to the National Mental Health Association, about one in every eight women will develop depression at some point during her lifetime. Women’s symptoms are similar to major depression. Some of them include being in a depressed mood, loss of interest in activities you used to like, feelings of guilt and hopelessness, and suicidal thoughts or recurrent thought of death. Women tend to blame themselves, feel anxious and scared, and avoid conflicts at all costs. They also use food, friends, and love to self-medicate. Some causes of depression in women are premenstrual problems, pregnancy and inf...
Menopause is the end of menstruation demonstrated by 12 consecutive months of no menstrual cycle due to decreased estrogen production. Perimenopause or “climacteric is the time before the actual cessation” of menses (deWit, 2015). The signs and symptoms that lead to menopause: hot flashes, night sweats because of vasomotor instability brought about by lower levels of estrogen, menstrual irregularity and changes. These changes make the vaginal wall thinner and more delicate potentially causing vaginal pruritus and increased risk for infections. Women entering the first stage of menopause need to be aware of the potential for painful sexual experiences known as dyspareunia. The onset of menopause can also have a negative effect on the psyche of a woman, noting that with the cessation of menses comes the realization that pregnancy is no longer an option. Some women view aging as a sign that they are less attractive, menopause signals the first step in to old age for many. The average age for women to reach menopause is “50 years old, with a range of 45-55 years” (Kee, J., 2012).
