UI	MeSH Term	Description	Entries
D008294	Malathion	A wide spectrum aliphatic organophosphate insecticide widely used for both domestic and commercial agricultural purposes.	Carbafos,Carbofos,Carbophos,Cythion,Karbofos,Prioderm,Sadophos
D002642	Chick Embryo	The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.	Embryo, Chick,Chick Embryos,Embryos, Chick
D004707	Endoderm	The inner of the three germ layers of an embryo.	Definitive Endoderm,Definitive Endoderms,Endoderm, Definitive,Endoderms
D006651	Histocytochemistry	Study of intracellular distribution of chemicals, reaction sites, enzymes, etc., by means of staining reactions, radioactive isotope uptake, selective metal distribution in electron microscopy, or other methods.	Cytochemistry
D000014	Abnormalities, Drug-Induced	Congenital abnormalities caused by medicinal substances or drugs of abuse given to or taken by the mother, or to which she is inadvertently exposed during the manufacture of such substances. The concept excludes abnormalities resulting from exposure to non-medicinal chemicals in the environment.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D015017	Yolk Sac	The first of four extra-embryonic membranes to form during EMBRYOGENESIS. In REPTILES and BIRDS, it arises from endoderm and mesoderm to incorporate the EGG YOLK into the DIGESTIVE TRACT for nourishing the embryo. In placental MAMMALS, its nutritional function is vestigial; however, it is the source of INTESTINAL MUCOSA; BLOOD CELLS; and GERM CELLS. It is sometimes called the vitelline sac, which should not be confused with the VITELLINE MEMBRANE of the egg.

D050260	Carbohydrate Metabolism	Cellular processes in biosynthesis (anabolism) and degradation (catabolism) of CARBOHYDRATES.	Metabolism, Carbohydrate
D050356	Lipid Metabolism	Physiological processes in biosynthesis (anabolism) and degradation (catabolism) of LIPIDS.	Metabolism, Lipid
