  • Blocks Other Sperm Cells
    2,049 words
    The theory of embryonic development we follow today was proposed 2000 years ago by Aristotle. This idea, called epigenesis, the form of an animal arises gradually from a generally formless egg. The organisms development is largely determined by the genome of the zygote and the organization of the cytoplasm of the egg cell. The first part of the development of a new animal is fertilization. The gametes, the sperm and the egg, are both highly specialized haploid cells that will combine chromosomes...
  • Journey From Zygote To Embryo To Fetus
    485 words
    "From the very moment that the sperm hits the egg, a precarious trip on the thin edge of biological extinction has begun" (Ralph Blair, Nevertheless Joy! ). The developing person is no less a wonder after birth than in the womb. The time spent in the womb, before birth, is so amazing. The journey from zygote to embryo to fetus is a beautiful trip. From the union of sperm and egg to birth of the newborn, development progresses in an orderly, though fragile, sequence. Fewer than half of fertilized...
  • Promise Of Stem Cell Research
    509 words
    Advancements in genetic engineering has been one of the most talked about subjects for many years. It has scared some but at the same time intrigued others. This question how far is too far, will play a big issue in years to come and even now for that mater. What people do not understand is that the research that is being done today is being done to help cure incurable diseases like the Aids virus and Cancer and it is not being done to create at perfect utopian society where everyone is the same...
  • Developing Mother And Child
    4,004 words
    Early Child Development There are many key factors that play up to the role of early child development, starting from before the child is nonexistent, until the child is a full grown baby. Bodily Processes of Reproduction There are numerous hormones in the human body that play key factors in allowing a human being to reproduce successfully. Spermatogenesis Spermatogenesis is the 65 to 75 day process in which the human male anatomy produces sperm cells. In the male body, follicle-stimulating horm...
  • Mother's Egg Cell And The Developing Child
    1,619 words
    Dear Mr. Shawn Nauman, This letter is in response to your March 1, 1995 editorial regarding abortion. It must have been very tough at times, growing up with parents who were so young and unprepared for a child. I must commend your parents for doing such a wonderful job of raising a son who grew up to be so vocal with his opinions and thoughts. I realize with your mother being a teenager at the time of your conception, and with the timing of her pregnancy, with regards to the infamous Roe vs. Wad...
  • Embryo Stem Cell Research
    1,059 words
    Stem cells show potential for many different areas of health and medical research, and studying them can help us understand how they transform into the dazzling array of specialized cells that make us what we are. Some of the most serious medical conditions, such as cancer and birth defects, are caused by problems that occur somewhere in this process. A better understanding of normal cell development will allow us to understand and perhaps correct the errors that cause these medical conditions. ...
  • Makers Of Medical Imaging Equipment
    817 words
    Now, with advances in genetic research, the makers of medical imaging equipment are retooling their cameras to spot tiny changes within cells that signal the start of a disease -- the point at which doctors have the best shot at a cure. 'It's totally different from the way we take care of patients now,' said Dr. Samuel Wickline, professor of medicine, physical and biomedical engineering at Washington University School of Medicine in St Louis, Missouri. 'Molecular imaging will enable you to detec...
  • Process Of A Developing Embryo And Fetus
    1,333 words
    Development of the Human Zygote November 16, 1995 Hundreds of thousands of times a year a single-celled zygote, smaller than a grain of sand, transforms into an amazingly complex network of cells, a newborn infant. Through cellular differentiation and growth, this process is completed with precision time and time again, but very rarely a mistake in the " blueprint' of growth and development does occur. Following is a description of how the pathways of this intricate web are followed and the mist...
  • Use Of Adult Stem Cells
    2,947 words
    What is a stem cell? Stem cells have the ability to divide for indefinite periods in culture and to give rise to specialized cells. They are best described in the context of normal human development. Human development begins when a sperm fertilizes an egg and creates a single cell that has the potential to form an entire organism. This fertilized egg is, meaning that its potential is total. In the first hours after fertilization, this cell divides into identical cells. This means that either one...
  • Embryonic Stem Cell Research
    2,840 words
    What exactly are stem cells? Stem cells are the mother of all cells in our bodies. They are cells that can develop into many different types of tissue, such as bone, muscle, or brain, and organs of the human body. When a fertilized egg first divides, totipotent stem cells are formed. These totipotent stem cells are cells that can turn into any type of tissue and form a complete organism. It is for this reason that stem cells have been the topic of many medical debates. In theory, these stem cell...
  • Active In Different Cells During Development
    383 words
    Normally, when a baby is born approximately nine months after being conceived, he or she has all the features of its parents. It is fully developed for life separate from its mother's umbilical cord. It is fascinating how they are formed inside the womb. Beginning from day one, life has started. Embyonic development is a complex process involving cell division, cell differentiation, and cell movement, as the genetic information from the parents are passed down to this new life (Arms 582). The fi...
