Study Notes
Definition of Pathology
- Pathology is the study of disease, specifically focusing on the structural, biochemical, and functional changes in cells, tissues, and organs that underlie disease.
Scope of Pathology
- Pathology attempts to explain the signs and symptoms of patients using molecular, microbiologic, immunologic, and morphologic techniques.
- It provides a rational basis for clinical care and therapy, serving as a bridge between basic sciences and clinical medicine.
Branches of Pathology
- General pathology: concerned with the reactions of cells and tissues to abnormal stimuli and inherited defects.
- Systemic pathology: examines the alterations in specialized organs and tissues responsible for disorders.
Aspects of a Disease Process
- Etiology (cause): the concept that certain abnormal symptoms or diseases are “caused” is ancient.
- Pathogenesis (mechanisms of development): the process of how a disease develops.
- Molecular and morphologic changes: the biochemical and structural alterations induced in cells and organs.
- Clinical manifestations: the functional consequences of these changes.
Etiology
- There are two major classes of etiologic factors: genetic (inherited mutations and disease-associated gene variants) and acquired (infectious, nutritional, chemical, physical).
- Most diseases are multifactorial, arising from the effects of various external triggers on a genetically susceptible individual.
