Which cell releases vasoactive amine so as to increase vascular permeability ?
Correct answer: C. Mast cell
- A. Leukocyte
- B. Marcophage
- C. Mast cell
- D. Fibroblast
Explanation
Mast cells store histamine, a vasoactive amine that rapidly produces arteriolar vasodilatation and increased venular permeability. Macrophages and leukocytes release other inflammatory mediators but are not the principal histamine-storing cells.
