Factors in a disability that have their etiology outside the person.

Factors in a disability that have their etiology outside the person.

• A. Endogenous Factors
• B. Exogenous Factors
• C. Intrinsic Factors
• D. Internal Factors

Answer: (B)

External causes are etiologies that originate outside the person. This includes events or conditions in the environment that contribute to disability, such as accidents, injuries, exposure to toxins, infections acquired from surroundings, or structural barriers in society. Because the phrase describes origins outside the individual, the term exogenous fits best. By contrast, factors described as internal, intrinsic, or endogenous come from within the person—such as congenital conditions or genetic disorders. So, when the disability’s cause lies outside the person, it’s exogenous.
