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 ...
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 ...
Parasitic Twins
(Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-25)
Parasitic twins, a specific type of conjoined twins, occurs when one twin ceases development during gestation and becomes vestigial to the fully formed dominant twin, called the autositic twin. The underdeveloped twin is ...
Conjoined Twins
(Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-25)
Conjoined twins are twins whose bodies are anatomically joined in utero. The degree to which the twins are attached can range from simple, involving skin and cartilage, to complex, including fusion of the skull(s), brain(s), ...
Fetus in Fetu
(Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-08-16)
Fetus in fetu is a rare variety of parasitic twins , where the developmentally abnormal parasitic twin is completely encapsulated within the torso of the otherwise normally developed host twin. In the late eighteenth ...
