noun, Biology. 1. the production or induction of malformations or monstrosities, especially of a developing embryo or fetus. Also called teratogeny.
The embryo is most susceptible to teratogenic agents. during periods of rapid differentiation. The stage of development of the embryo determines suscep-. tibility to teratogens. The most critical period in the development of an embryo or in the growth of a. particular organ is during the time of most rapid cell division. The critical period for each organ is. pictured below (Fig. 23-2). For instance, the critical period for brain growth and development is. from three to 16 weeks.
