During maturation/remodeling, how is collagen organization in scar tissue affected?

• A. Collagen in scar tissue is more organized
• B. Elastin is present in scar tissue
• C. Collagen in scar tissue is less organized
• D. Scar tissue is more elastic

Answer: (C)

During maturation/remodeling, collagen fibers are reorganized and realigned to run along the lines of stress, which increases the scar’s tensile strength. This process includes a shift from weaker type III collagen to stronger type I collagen, and the fibers become more orderly over time rather than forming a chaotic weave. Elastin is not restored to normal levels, so scar tissue remains less elastic than surrounding tissue. In short, collagen organization improves during remodeling, not becomes more disorganized.
