Document Summary

This module gives you some fundamental definitions of disease and related terminology and the framework by which to classify disease. Chromosomal abnormalities - a change in the normal number of chromosomes (normally 22 pairs plus sex chromosomes (either xx or xy)) or in their normal structure. Disease - very simply, a change in normal body function/structure that leads to abnormal function (e. g. resulting from a direct insult, such as trauma or infection, or an indirect insult, such as a disturbance in metabolism). Etiology - the study of the cause(s) of disease. Iatrogenic - disease caused as the result of a medical treatment. Idiopathic - of unknown origin; used when we don"t know the cause of disease. Morbidity - the impairment of health by illness. Mortality - causing the death of the patient. Pathogenesis - the stages through which a disease progresses; the production and development or mechanism of disease. Pathology - the study of disease (causes, typical characteristics and effects).
