Cellular theory of disease The belief that disease was due to one diseased cell creating another diseased
cell.
Who created the Cellular Theory of Disease, and in what Rudolf Virchow
year? 1858
What are the 3 categories of death? 1. deaths due to diseases-causing microorganisms like those that cause AIDS,
tuberculosis, or the flu.
2. deaths due to degenerative pathological disorders like heart disease or strokes.
3. deaths due to by-products of the social environment, as in the cases of suicide,
murder, or vehicular accidents.
Pathology The study of suffering. It incorporates the aspects of clinical practice as well as
basic science.
Etiology Study of the underlying causes of diseases and the pathogenesis of disease (the
mechanism that results in the manifestations of signs and symptoms in the body.
Pathogenesis The mechanism that results in the manifestations of signs and symptoms in the
body.

5 Divisions of Pathology 1. Gross Pathology- the study of changes in the structure of the body that are
readily seen with the unaided eye as a result of disease.
2. Histopathology- also known as microscopic pathology, is the study of
microscopic changes that cells, tissues, and organs undergo as a result of disease.
3. Surgical pathology- the study of tissue specimens excised surgically during
operations.
4. Clinical Pathology- the study of disease by means of body secretions,
excretions, and other bodily fluids in the diagnosis of disease.
5. Physiological pathology- the study of changes in body function due to disease.
6. Medicolegal pathology- also known as forensic pathology, this is the study of
disease to ascertain the cause and manner of death
Pathological Anatomy Also known as morbid anatomy, this is the study of structural changes in the body
caused by disease. It includes both gross and histopathology.
2 fields of pathology 1. General pathology- Focus on the cellular and tissue responses to pathological
stimuli, deals with the study of the widespread process of disease, such as
inflammation, degeneration, necrosis, or cellular death, and repair without
reference to particular organ or organ systems
2. Special Pathology- deals with the specific features of disease in relation to a
particular organ or organ system, also referred to as systemic pathology.
