Multi-Fetal Pregnancy
(Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-25)
In humans, multi-fetal pregnancy occurs when a mother carries more than one fetus during the pregnancy. The most common multi-fetal pregnancy is twins, but mothers have given birth to up to eight children (octuplets) from ...
Corpus Callosum Defects Associated with Fetal Alcohol Syndrome
(Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-10)
Prenatal exposure to alcohol (ethanol) can result in a continuum of developmental abnormalities that are highly variable depending on the severity, duration, frequency, and timing of exposure during gestation. Defects of ...
Abortion
(Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-08)
Abortion is the removal of the embryo or fetus from the womb, before birth can occur-either naturally or by induced labor. Prenatal development occurs in three stages: the zygote, or fertilized egg; the embryo, from ...
Amniocentesis Prior to 1980
(Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-10)
The extraembryonic membranes that surround and originate from the embryos of vertebrates such as birds, reptiles, and mammals are crucial to their development. They are integral to increasing the surface area of the uterus, ...
Rh Incompatibility in Pregnancy
(Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-10)
Rh incompatibility occurs when a pregnant woman whose blood type is Rh-negative is exposed to Rh-positive blood from her fetus, leading to the mother s development of Rh antibodies. These antibodies have the potential to ...
Effect of Prenatal Alcohol Exposure on Radial Glial Cells
(Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-25)
Prenatal alcohol (ethanol) exposure can have dramatic effects on the development of the central nervous system (CNS), including morphological abnormalities and an overall reduction in white matter of the brain. The impact ...
Diprosopus (Craniofacial Duplication)
(Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-25)
Diprosopus is a congenital defect also known as craniofacial duplication. The exact description of diprosopus refers to a fetus with a single trunk, normal limbs, and facial features that are duplicated to a certain degree. ...
Twin-to-Twin Transfusion Syndrome
(Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-25)
Twin-to-Twin Transfusion Syndrome (TTTS) is a rare placental disease that can occur at any time during pregnancy involving identical twins. TTTS occurs when there is an unequal distribution of placental blood vessels between ...
Role of Sonic Hedgehog (Shh) in Alcohol-Induced Craniofacial Abnormalities
(Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-25)
Prenatal exposure to alcohol (ethanol) results in a continuum of physical and neurological developmental abnormalities that vary depending on the timing, duration, and degree of alcohol exposure. Heavy exposure during ...
