Which staining approach is known for distinguishing multiple tissue components with different colors on a single slide?

• A. Hematoxylin and eosin
• B. Movat pentachrome
• C. Giemsa
• D. PAS

Answer: (B)

Movat pentachrome staining is designed to distinguish several tissue components within a single section by using a combination of dyes that produce distinct colors for each element. In this method, collagen appears yellow, muscle and fibrin show red, elastic fibers stain black, and mucin or sulfated mucopolysaccharides appear blue. This multi-color differentiation makes it especially useful for evaluating connective tissue structures, vasculature, and surrounding matrix on one slide. In comparison, hematoxylin and eosin gives broad two-color contrast (nuclei versus cytoplasm), Giemsa is primarily used for blood cells and some parasites, and PAS highlights carbohydrates and glycogen in a single color family rather than a spectrum of components.
