Elastin presence in scar tissue is described as which of the following?

• A. Elastin is present in scar tissue
• B. Elastin is not present in scar tissue
• C. Elastin increases scar tissue elasticity
• D. Elastin is degraded during remodeling

Answer: (B)

Elastin provides elasticity and recoil in normal tissue, but during scar formation the repair process lays down a dense collagen matrix and little to no elastin is reconstituted. This means scar tissue has minimal elastin content, contributing to its reduced elasticity compared with normal tissue. While remodeling involves matrix turnover, elastin fibers are not significantly regenerated, so describing elastin as present or as increasing elasticity doesn’t fit scar tissue.
