Essays on Ovum

Cloning is the process that a cell or an organism is produced asexually; meaning that no sex is involved in their formation and the product is identical to a specific ancestor. Animal cells are cloned simply because they can be produced from one fertilized cell and they are also genetically identical. In simpler terms, cloning is the process of producing many duplicate cells of an organism. In some cases, cloning is a natural process shown bacteria which are single celled, as well as identical twins in human beings and mammals. The process is also made possible to the animals ...

People hold different views on matters of contraception in relation to abortion and Marquis is no different. According to him, abortion is immoral since it deprives the fetus the benefits it ought to enjoy in the future as well as the art of appreciating its current position as a fetus. He excludes the abortions done with regards to special cases such as prior to implantation, if the life of the mother is threatened by the fetus and in cases of rape. He, however, does not view the use of contraception in relation to abortion as morally wrong even though ...

- The stromal cells that are found in the developing gonads of tetrapods begin from the medulla from the peritoneal wall and the cortex from inter-renal blastema or mesonephric. Hence the gonads have a dual origin. - Spermatogenesis occurs in a syncytial complex because it involves the formation of sperm from undifferentiated cells that are first attached to rachis. Syncytial cell complex or syncytium result when cells with single nuclei fuse to for a cell with nucleus. Syncytial cell complex is vital in oogenesis in that it assists in the differentiation of cells. One other developmental model is vitellogenesis. - ...

Teratogens are genotoxins that can potentially disrupt the genetic makeup of developing cells, resulting in aberrations that can manifest disabling physical and mental abnormalities in a fetus. Teratogens can cross the placenta and reach the fetus, which quashes the popular belief that a fetus is shielded from external harmful influences. This indicates that the placenta is incapable of blocking teratogenic metabolites from reaching the fetus. Teratogenesis can be defined as birth defects or congenital malformations occurring in utero due to exposure to external factors. Such factors could be environmental, chemical or biological in nature. Factors such as the time of exposure, ...

Definition and Causation of Edward’s Syndrome

Edwards’s syndrome is a condition and severe genetic disorder caused by a chromosomal defect. The syndrome occurs in approximately 1out of every 6,000 live born infant (Trisomy 18 Foundation, 2010). A human bring is supposed to have 46 chromosomes, of which, 23 are obtained from the mother while the other 23 are obtained from the father. With in mind that conception is usually the fusion of male and female gametes (sperm and ovum), in case of an error in the formation of any of the two gametes, there is a high prospect that the baby formed from such gametes will ...

Stem cell research has been termed by the medical research fraternity as one of the greatest milestones in human health science. Stem cells can be defined as any kind of cell that can divide through mitosis and thereby specialize into any of the several different kinds of cells found in the human body. This specialization of the cells into any of the functional cell in the body means that doctors can use it to heal many cell-associated diseases. For example, there diseases and condition that lead to the damage of the neural cells in the brain or the spinal ...

The term bioethics was coined in the early 1970s by biologists who brought to the public’s attention two pressing issues; the need to maintain the plant’s ecology and the implication of advances in the life sciences toward manipulating human nature. Van Rensselaer Potter has focused on the growing human ability to change the nature, including human nature and the implication of this for our global future [ CITATION Van71 \l 1033 ]. While bioethics has been interdisciplinary since its inception, theology played a fundamental role in its creation. It continues to have a profound influence today also. At its inception, ...

Introduction

Abortion refers to the “termination of pregnancy before fetal viability” (Littleton and Engebretson 508). In this definition, a ‘viable fetus’ refers to one that has thrived for at least twenty weeks after conception. Abortion can broadly be classified into two categories: 1. Spontaneous Abortion: Also known as a miscarriage, this type of abortion refers to the termination of pregnancy without human interference (naturally) (Littleton and Engebretson 508). 2. Induced Abortion: This refers to “termination of pregnancy before fetal viability by medical or surgical intervention” (Littleton and Engebretson 508). This category can further be subdivided into two subcategories: (i) Therapeutic ...
