An Introduction to General Pathology
- The term pathology is derived from:
- Pathos, or suffering
- Logos, or reasoning/logic.
- Pathology is defined as the study of disease including:
- Aetiology - causal factor(s)
- Pathogenesis - the development of the disease within the body.
- Lesions - the observable structural changes in the tissues and fluids of the body.
- Pathophysiology - the functional changes in diseased tissues.
- Sequel - the consequences of the disease in the body.
- Remote effects - the effect of disease in one tissue on other tissues in the body.
Lesions
- Lesions are the abnormalities or changes seen in living tissues due to disease.
- Observed in
- The live animal
- Tissues surgically removed from the live animal
- Biopsy/ excision
- In animals soon after death
- Necropsy, post-mortem examination.
Decription of Lesions
- Descriptions of lesions is very important
- Whole organs, tissues or individual lesions are described under headings such as
- Size
- Shape
- Colour
- Weight - generally referred to body weight
- Texture and Consistency
- Appearance of the cut surface
- Contents of hollow organs
- Position, relationships and effects on adjacent tissues
