Study Notes
Introduction to Inflammation
- Inflammation is a protective response involving host cells, blood vessels, and proteins/mediators.
- The objectives of inflammation are to eliminate the initial cause of cell injury, remove necrotic cells/tissues, and initiate the repair process. However, the inflammatory response itself can cause harm.
Acute vs. Chronic Inflammation
- Acute inflammation: onset is fast (minutes/hours); cellular infiltrate is primarily neutrophils; usually mild and self-limited; prominent local and systemic signs.
- Chronic inflammation: onset is slow (days); cellular infiltrate includes monocytes/macrophages and lymphocytes; often severe and progressive; less prominent local/systemic signs, potentially subtle.
Cardinal Signs of Inflammation
- The external signs (cardinal signs) of inflammation are heat (calor), redness (rubor), swelling (tumor), pain (dolor), and loss of function (functio laesa).
Naming Inflammation
- Inflammation is often named by adding the suffix "-itis" to the affected body part (e.g., appendicitis, gastritis).
