Developmental toxicity is any developmental malformation that is caused by the toxicity of a chemical or pathogen. It is the structural or functional alteration, reversible or irreversible, which interferes with homeostasis , normal growth , differentiation , development or behavior.
Environmental toxicants and fetal development is the impact of different toxic substances from the environment on the development of the fetus. This article deals with potential adverse effects of environmental toxicants on the prenatal development of both the embryo or fetus, as well as pregnancy complications. The human embryo or fetus is ...
The infants were studied by dysmorphologists Kenneth Lyons Jones and David Weyhe Smith, colleagues of Ulleland at University of Washington, [123] who identified a pattern of "craniofacial, limb, and cardiovascular defects associated with prenatal onset growth deficiency and developmental delay" in eight children. The pattern of malformations ...
Teratology is the study of abnormalities of physiological development in organisms during their life span. It is a sub-discipline in medical genetics which focuses on the classification of congenital abnormalities in dysmorphology caused by teratogens and also in pharmacology and toxicology.
Reproductive toxicity refers to the potential risk from a given chemical, physical or biologic agent to adversely affect both male and female fertility as well as offspring development. [1] Reproductive toxicants may adversely affect sexual function, ovarian failure, fertility as well as causing developmental toxicity in the offspring.
Other studies have shown that low SES is closely associated with the development of the fetus in utero and growth retardation. [80] Studies also suggest that children born in low SES families are "likely to be born prematurely, at low birth weight, or with asphyxia, a birth defect, a disability, fetal alcohol syndrome, or AIDS". [80]
Lead poisoning interferes with the normal development of a child's brain and nervous system; therefore children are at greater risk of lead neurotoxicity than adults are. [203] In a child's developing brain, lead interferes with synapse formation in the cerebral cortex , neurochemical development (including that of neurotransmitters), and ...
The Amanita muscaria mushroom, an iconic toxic mushroom. A toxin is a naturally occurring poison [1] produced by metabolic activities of living cells or organisms. [2] They occur especially as proteins, often conjugated. [3] The term was first used by organic chemist Ludwig Brieger (1849–1919), [4] derived from toxic.
