1. Introduction Flashcards
What is pathology?
Scientific study of the diseases, the origin and development of disease
The study of structural and
functional changes in disease.
Etiology
Study of the cause of disease
What is a disease?
A disease is a physical or structural disorder that places individual at risk.
What is disease?
A structural or functional disorder that places ind. at risk to bad consequences.
Structural disease- Organic

Pathogenisis
Pathogenesis is sequence of
events from the initial stimulus
to the ultimate expression of
the disease
Who makes the diagnosis?
Clinicians, pathologist, and radiologist
Prognosis
Future predictions
Prognosis
Futre prediction
Pathologist
Physician identifying diseases
based on the examination of
cells and tissues removed
from the body
Complication
a second disease,
problem or condition aggravating an
already existing one and make the
situation more difficult
Microscopic pathology
The “gross, microscopic and
biochemical structure” of diseased
cells and tissues
Degree of deviation from normal
Grade
Extent of disease
Stage
What is morphology?
Abnormal Anatomy
• Gross
• Microscopic
• Radiologic
• Molecular
Role of pathologist
• Definite Diagnosis
• Assessment of adequacy of treatment
• Prognosis evaluation
• Effective communication
• Research.
Why pathology important
- Perfect patient care
- Accurate diagnosis and treatment
- Screening and preventing diseases
Father of modern Pathology
Rudolf Virchow
