2. Health and Disease. Main categories in pathology (etiology, pathogenesis, morphogenesis, sanogenesis, tanatogenesis)

Question 1

What is Pathology?

Answer 1

Scientific Study OF

Structure + Function of Body in Diseases

Devoted to study Structural + Functional Changes in Cells / Tissues / Organs

THAT Underlie Diseases

Question 2

What 4 Types of Pathological Study

Answer 2

1. Cause of the Disease = Etiology
2. Mechanisms of its Development = Pathogenesis
3. Structural Alterations of Cells, Organs + Tissues of Body = Morphological Changes
4. Functional Consequences of Morphological Changes = Clinical Significance

Question 3

What is Health?

Answer 3

Sustainable Dynamic Equilibrium of Organism WITH the Environment

Where Correlation BTW Structure + Function ALLOWS Body to Realise its Biological Potential

Question 4

What is Disease?

Answer 4

Significant Disturbance of Normal Function of Body

DUE to Changes in Environment / Weakness of Biology of Individual

Question 5

What is ‘Etiology’?

Answer 5

Studies the CAUSATIVE FACTORS of the Disease

Question 6

What is ‘Pathogenesis’?

Answer 6

Studies the Mechanism of Disease Development

ALLOWING the Treatment to be Determined

Question 7

What is ‘Morphogenesis’?

Answer 7

SERIES of Local Structural Changes

IN Course of a Disease

Question 8

What is ‘Pathognomonic Changes’?

Answer 8

Changes SUFFICIENT to make a Diagnosis

Question 9

What is ‘Sanogenesis’?

Answer 9

Studies Mechanisms of Healing

Question 10

What is ‘Tatanogenesis’?

Answer 10

Studies Clinical / Morphological + Biochemical Changes

OCCURS in Process of DEATH
