Substances that are suspected of causing malformations or serious deviations from the normal type, which can not be inherited in or on animal embryos or fetuses
Substances such as chemicals or radiation that cause abnormal development of a embryo See also: mutatgen
Abnormalities production during embryonic development leading to foetal malformations Three-phase current : Three wires under tension or conductors are used instead of only one, each one functioning with the same alternating voltage, and generally transporting the same AC current, but the three tensions are shifted (temporal variation) a third of a period compared to each other This means that the sum of the three tensions (or the currents) is zero at every moment A three-phase transmission makes it possible to transmit as with three conductors the same energy as with three identical circuits of two wires for each one, that is to say a saving in 50 % of matter The three waves (A,B,C) represent the voltages ( and currents ) in a three-phase system Source : CIGRE Tissue: Set of cells of comparable nature specialized to perform the same function The tissues form the organs
drugs given to the mother that can cross the placental barrier to the unborn child They are caplable of interfering with the development of the fetus, causing birth defects
The property of a substance or mixture of substances to produce or induce (Teratogen) functional deviations or developmental anomalies, not heritable, in or on an animal embryo or fetus
