Embryo

(Dalton, Clancy 830-668-602) “I have not given, received, or used any unauthorized assistance on this assignment.” Once the embryo reaches two to eight weeks, it begins to differentiate. Differentiation is the process that cells undergo to become specialized; a cell transforms from a general cell to a muscle cell which has differing characteristics in comparison to an unspecialized cell. At this stage as well as all stages of fetal development, it is especially important that the mother does…

While in the uterus the structure called the placenta exchanges the nutrients between the pregnant woman and the developing child. About 3 weeks after this process has begun the embryo is formed by the zygote fully embedding itself in the uterine wall. During this the body structure is formed. The organs are growing. The embryo environment rest in a sac called…

developed and know they will never be even after birth. In the article, The Moral Status of the Human Embryo: When is a person a person? Dr. Peter Saunders gave some interesting example on his thoughts. He wrote in his writing, “Human embryos are not human beings worthy of respect because they have a high mortality; about 40-70% don’t reach maturity.”(Saunders) No one really knows at what point an embryo can pass away all of a sudden but have a higher risk than a…

two lateral hemispheres. It is roughly spherical but somewhat constricted in its median region and flattened, the greatest diameter being transverse. The cerebellum develops from the dorsolateral part of the alar lamina of the metencephalon. In the embryo cerebellum appears at the end of the fifth week as a swelling overriding the fourth ventricle. Since cerebellum lies in the posterior cranial fossa, surrounded by the dense petrous ridges and the occipital bone so it can withstand deformation…

When a expectant mother’s nutritional status can affect the birth. The first stage of gestation the mother must be well nourished so that the formation of the placenta will be healthy. The embryo and the fetus are major body organs that form within 2 to 3 months of conception. Nutrition at this time is very critical for the health of the child. The best action for a pregnant woman to take is to enter the pregnancy with good nutrient stores and to consume a well-balanced diet. The mother needs…

Klinefelter syndrome that are trying to conceive a child. For this procedure, a surgeon removes sperm from the testes injected into a needle and places one sperm into an egg cell to begin fertilization. If successful the egg cell will begin reproducing an embryo, the procedure will not work for some individuals. To treat language and learning symptoms individuals assists a physical therapist as it is designing to build motor skills. Individuals with Klinefelter syndrome have learning…

period. The embryo’s limbs grow to form webbed feet and hands and the thyroid, adrenal glands and pituitary glands have fully formed and their eyes are now open. At week 8 a diagnostic ultrasound scan can be offered to the mother. At 12 weeks the embryo is now known as a foetus and all the organs and muscles are fully formed. The sex of the foetus is now apparent. The webbed feet and hands are fully grown fingers and toes. A second scan can be offered during this time as well. The heartbeat may…

Germination is the transition from mature embryos to an actual plant containing both a root and a shoot. This involves having a visible root and shoot as well as cotyledon elongation. (Attree 1990) Once the seed germinates, both a root and a shoot forms, and the seed capsule is pushed up, out of the dirt by the stem before it falls off. The different treatments used in this study affected the overall germination of the Picea mariana seeds. The seeds which were only treated with distilled water…

The developmental psychology has seven stages this includes infancy, childhood, lover, solder, justice, old age and, finally, dementia and death. Shakespeare’s seven stages into developmental psychology concepts would correlate with the stages of life span development. The first prenatal stage of development is when the beginning of conception and last two weeks. The zygote single cell, that results when a sperm fertilized an egg. This happens when the ovum is fertilized in the fallopian tube.…

Is it possible to grow human fetuses outside a mother’s womb? The idea that was once a fantasy in the realm of 1932’s novel Brave New World by Aldous Huxley, in which human fetuses gestated inside the test tubes; is no longer a simple LSD trip the author had when he conceived this story, but now part of our reality (Paula Mejia, Fetuses in Artificial Wombs: Medical Marvel or Misogynist Malpractice? page 1). So, foregoing of having test tubes, the scientist has created a womb out of endometrial…
