Study Notes
Macrophage Activation & Inflammatory Response
-
Classically activated macrophages promote inflammation.
-
Alternatively activated macrophages suppress inflammation.
Tissue Repair
-
Granulation tissue is composed of fibroblasts, loose extracellular matrix, new capillaries, and inflammatory cells.
-
Superficial injuries often heal through regeneration, where damaged tissue is replaced with identical tissue.
-
Severe injuries typically heal via scar formation, resulting in the formation of fibrous connective tissue.
Granulomatous Inflammation
- Granulomatous inflammation is characterized by the formation of granulomas, which are clusters of epithelioid cells, giant cells, and T lymphocytes.

Description
This quiz covers the roles of macrophages in inflammation and tissue repair. You'll explore classically and alternatively activated macrophages, the process of granulation tissue formation, and the characteristics of granulomatous inflammation. Test your knowledge on how different injuries heal and the significance of macrophages in these processes.
