What term describes congenital abnormalities caused by mechanical forces?

The term that describes congenital abnormalities caused by mechanical forces is "Deformation." This occurs when the shape or structure of a developing fetus is altered due to external physical pressures, such as those from the uterine environment, constraints from amniotic fluid, or maternal factors.

In contrast, malformations arise from intrinsic factors, such as genetic mutations or developmental errors in the formation of tissues or organs. Disruption involves the breakdown of an originally normal tissue or structure due to environmental factors, and a sequence refers to a pattern of anomalies that stem from a single initial defect leading to a cascade of related issues. Understanding these distinctions is essential for accurately describing and diagnosing different types of congenital abnormalities.
