Agenesis
From Wikipedia, the free encyclopedia
Agenesis is the medical term for the failure of an organ to develop during embrionic growth and development. Agenesis of key organs such as the heart and brain is usually fatal. However, for those organs which occur in pairs, the loss of one member (i.e. "unilateral agenisis") is not.
[edit] Conditions
Many specific examples of agenesis are referred to by individual names, depending on the organ affected.
- Agenesis of the corpus callosum- failure of the Corpus callosum to develop.
- Renal agenesis- failure of one or both of the kidneys to develop.
- Phocomelia- failure of the arms or legs to develop, often caused by the drug thalidomide.
- Penile agenesis- failure of penis to develop.
[edit] Alternate Definition
In theology and origins science, agenesis means to have no beginning or to have no creator. To come into existence without the influence of an outside intelligence.
