Topic: Fetal development

  Fetal development - Wikipedia, the free encyclopedia
Fetal (U.S. English; "Foetal" UK English) development is the process in which a fetus (U.S. English; "Foetus" UK English) develops during gestation, from the times of conception until birth.
A spontaneous abortion, or miscarriage, in the first trimester of pregnancy is usually due to major genetic mistakes or abnormalities in the developing embryo.

 Fetal Alcohol Syndrome
Fetal alcohol syndrome (FAS) is a serious health problem that tragically affects its victims and their families, but that is completely preventable.
Victims of fetal alcohol syndrome often experience mental health problems, disrupted school experience, inappropriate sexual behavior, trouble with the law, alcohol and drug problems, difficulty caring for themselves and their children, and homelessness.
Not a single case of fetal alcohol syndrome occurred and no adverse effects on children were found when consumption was under 8.5 drinks per week.

 Pregnancy and Fetal Development Benefits of Omega-3 Fatty Acids
It is well established that humans, at both the fetal and infant stage, require an adequate supply of omega-3 and omega-6 long-chain polyunsaturated fatty acids for optimal growth and neural development.
These essential oils are the main component of a developing fetal nervous system and retina and are necessary throughout the entire process of pregnancy for the health and well being of the fetus.
Although the developing fetus requires DHA throughout the pregnancy, this vital nutrient is particularly important during the third trimester.

Low fetal birth weight-This low weight is not caused by prematurity but apparently due to reduced levels of oxygen delivered by the mother to her developing infant.

 Mammary Development - Fetal
Thus, the male pattern (masculinization) of mammary development is indicated at birth of the mouse fetus as the absence of nipples and the female pattern is indicated by the presence of nipples.
Mammary development of male fetuses are not further affected by the testosterone treatment of the mother.
Injection of growth hormone into the mouse fetus increases the size of the developing mammary gland in both male and female fetuses, suggesting that this hormone is also involved in development of the mammary gland during the fetal stage.

 Fetal Development Presentation
In the fourth week of development, the flat disk becomes cylindrical in structure-as the human body is cylindrical, with the skin on the outside, skeletal muscles in the middle, and the gastrointestinal tract in the center (Hole, 1994).
Corticogenesis, the development of the prospective cortex, begins at about the eighth week and continues for much of the rest of gestation and is probably influenced by the brainstem.
The developing cortex remains unconnected to the brainstem and the rest of the developing nervous system until about mid-gestation when the connection is made through a structure called the thalamus, which transmits sensory input from the rest of the nervous system to the cortex (DeCamp, 1997).

 Fetal development
A single sperm penetrates the mother's egg cell (ovum) and the developing child gets half of its genetic information (in the form of DNA) from the mother (this is contained in the egg), and half from the father (from the sperm).
A ball of cells is produced, each cell including a copy of the genes that will guide the development of the baby.
Once there are about 32 cells, the developing baby is called a morula.
