Cycles, Conception and Contraception
Fertility is the condition of being fertile. The aim of contraception is to
inhibit fertility in individuals, hence, slowing population growth. The system
by which all female contraception must operate: the menstrual cycle.
What is the menstrual cycle? and what hormones are involved in controlling it?
After puberty, the female produces an egg each month. Other changes take place
on a cyclic basis including the uterus lining and hormone levels. These changes
are called the menstrual cycle. Follicle stimulating hormone (FSH) from the
pituitary gland stimulates the growth of follicles in the ovary. Follicles
produce oestrogen that stimulates the pituitary to produce leutinising hormone
(LH). As LH increases the size of the follicle increases until an egg is
released. The corpus luteum formed in the follicle secretes progesterone that
prepares the lining of the uterus for pregnancy. If fertilisation does not occur
the lining of the uterus is discharged from the body in the process called
menstruation.
What is the birth control pill?
The combined oral contraceptive pill (the pill) is a reversable, hormonal
method of birth control. The pill consists of a mixture of two synthetic
hormones similar to oestrogen and progesterone, the woman’s natural hormones
which regulate the menstrual cycle. The pill is on of the most popular methods
of birth control.
How does it work?
The pill basically prevents ovulation, therefore, the ovaries can’t release a
mature egg. Without an egg for the sperm to fertilize , a woman cannot get
pregnant . The hormones also increase cervical mucus, making it difficult for
sperm to pass into the uterus.
How effective is the pill?
If used correctly, the pill is highly effective. It has a less than one percent
failure rate. However, because many people misuse it, the actual failure rate is
more like three percent. The pill does not provide protection against sexually
transmitted diseases.
How are pills used?
One pill must be swallowed at the same time every day. It is not any single
pill, but the day-to-day process of taking the pill which provides protection
against pregnancy.
What is infertility?
Infertility in humans and other species(animals) is the inability to concieve or
carry a pregnancy to a live birth. The causes of infertility can be identified
in some cases. The majority of cases relate to female factors (50%), 40% relate
to male factors and 10% aree unknown. Infertility sometimes may serve as a
combination of both male and female factors.
If the cause of infertility is known, treatment of some kind may be available.
In other cases a problem may disappear on its own and fertility is restored.
their mother's egg, but a man that spends time with and takes care of them.
Over time, the sperm and egg have evolved to be different. The article mentions the challenges with the sperm being able to reach the egg. There is also a discussion about how the protein affects the reproduction and a discussion on reproductive failure. The main concepts are how the egg and sperm reproduce, the challenges the sperm faces to get to the egg, how the egg and the sperm have evolved over time, and protein affects reproduction and reproductive failure. The outer shell of the egg has a sugary compound that allows the sperm to bind to the egg, resulting in reproduction.
Theogony, is the personification of things and ideas the ancient Greek, whereas Genesis is conflict between the hu8man like god and the mystical formless god. . Theogony, when compared to Genesis is radically different. Theogony starts from chaos and end up in order. In Genesis, creation is done by command alone. God says "water" and water appears. There is no conflict of interests or bloody battle. Genesis has the pattern of nothing to everything. Theogony has the pattern of chaos and powerful rulers to set order and gods with magical powers who use thought instead of raw power. There is a god of the sun, of wheat and of war. In Genesis there is one god of everything.
Black Lives Matter (BLM) movement was created to show the injustices that were being taken against the African American community. What no one was able to predict was the fact BLM started to actually discriminate and overlook members of their own race due to subtle differences like gender or sexual orientation. This type of overlook had to be correct by the BLM community in order to show solidarity inside the movement in order not to overlook anyone inside the African American race.
(Buchanan, Blue Lives Matter) Meanwhile, on the opposite side of the board among political self-education and a social identity crisis, the Black Lives Matter group is pushing for a civil rights movement and is hell bent on shaking the political pillars and releasing this country from its current cycle of violence and silence. (Sidner-Simon, The Rise of Black Lives Matter: Trying to break the cycle of violence and silence) Amid other routes, this plan has the possibility to take flight and soar, but the more likely solution will be that like its predecessors, it will most likely founder due to a government well versed in uprisings, and will leave is as a nation beaten black and
Yet, the manner in which BLM is handling ‘racism’ is harming communities around the country. There are cultures that should be feared, ones that breed violence and crime, but there are strong black cultures that have risen above the stereotypes that haunt them. Based on the culture that people are raised in, they are more inclined to commit violent crimes (Shaw 15). There are so many successful black people in the world. In the article “Making Black Lives Matter,” Mitchell Shaw gives a powerful example of that when he says: “Racism is incapable of holding black people down. Evidence of that is easy to find. Not only is a black man sitting in the Oval Office, but blacks hold power in cities all across America. That would never happen in a world that was holding black people down” (Shaw 13.) When taken into consideration, there are many African Americans that have accomplished amazing feats, even something as taken-for-granted as graduating college and getting a middle class job. They are the true American heroes that this country was founded
...rect influence on Greek creation mythology. But the truth is that the tables date back to 1100 BC, which means the Babylonian creation myth is much older then Greek mythology’s Theogony by Hesiod. The Enuma Elish might even contain stories that much other then itself, some scholars argue. In conclusion it is obvious that there are many parallels between the Enuma Elish and the Theogony. No matter the creation myth there will most always be unexplainable similarities that cannot be explained. Comparing and contracting different creation myths is a very good way to help explain different cultures and their differences and similarities. It also opens the door to more questions that seek answers only found by looking in the past and how can any culture hope to have a rich and valuable future without being aware of it’s past; this is why creations myths are so valuable.
The heart goes through many stages of change during embryonic development including those of cardiac looping and heart tube fusion (Martinsen 2005). The heart is of interest as many fatalities are due to heart defects and understanding the changes throughout the process of heart development could help with identifying the causes and treatments for these defects. In this report, the structure of the heart in the chick embryo at 40 and 56 hours will be compared.
Hesiod’s Theogony and the Babylonian Enuma Elish are both myths that begin as creation myths, explaining how the universe and, later on, humans came to be. These types of myths exist in every culture and, while the account of creation in Hesiod’s Theogony and the Enuma Elish share many similarities, the two myths differ in many ways as well. Both myths begin creation from where the universe is a formless state, from which the primordial gods emerge. The idea of the earth and sky beginning as one and then being separated is also expressed in both myths.
It was a tie between a psychologist and a social worker that I wanted to research. All this time I thought I wanted a career in psychology. Going through all that I have really learned about myself, I felt that I am better rounded for a career in social work. I believe that I have the skills and I will gain the knowledge to make it in this career. I also learned that just like psychology, there is many sub areas of social work. I could be working with people with disabilities, those with addictions, and my personal favorite children (OOH). Lastly, depending on what area interests me the most, the salaries do differ and each area will be continuing to grow in population.
In class, I was giving the assignment to reflect my thoughts about the social work profession and what I like to pursed in the future. I knew since I was young that I wanted a career where I could help people who were in need or do not have a voice to speak up. I wanted a career that helped change peoples’ lives and made me feel like I was making a differences in someone’s life. A career that I got to wake up every day that made me feel like I was changing the world. However, I did not know what major to consider. So, my senior year in high school, I had the opportunity to get into a program called Medical Topics. Through this program, I had the opportunity to shadow nurses, doctors, and other people in the hospital. I got to understand and
I have chosen social work as a profession because of my passion to help others. I want to make a difference in someone’s life and help them through the problems they are having. Whether the client needs counseling, guidance, or advocacy I want to be the person to help them. My drive for helping others and motivation to change social policies for the better is why I have chosen social work as my future profession.
Throughout history many civilizations and cultures have had their own ways of explaining the world and its creation. Each of these civilizations has created unique descriptions and accounts of such events. However, when comparing them to each other, are they really different? Look at the ancient Greco - Roman creation myths as told by Hesiod in his Theogony and Works and Days and Ovid’s Metamorphoses, when compared to the creation myths as seen in the Old Testament’s book of Genesis they may not be as different as one would think. Taking a more in-depth look at both Genesis and Hesiod’s and Ovid’s work more closely, the reader can see that on multiple occasions the myths have almost identical similarities which reflect their views in society. The similarities in particular are the myths of the creation of man, women with their subsequent role of evil in ancient times, and the great floods. These similarities prove that even though these two scriptures were centuries apart, the concepts presented in each myth were almost identical to one another.
Hi fellow classmates. When preparing for a career in social work there are considerations that need to be made. One of the considerations that brought me on my path to becoming a social worker is my passion for helping others and because of this have always sought out employment where I can promote social justice and the well-being of others. Another consideration was having a career where I would continue learning. It has only been over the last few years that I have discovered the joy and feeling of accomplishment that comes with continuously learning and gaining knowledge. Other considerations that I were taken into account before I began my journey were my ability to practice self-awareness and knowing what my biases where and being able
