What is an effect of tension during fibroplasia and consolidation?

• A. Inhibits collagen synthesis
• B. Randomizes collagen alignment
• C. Stimulates collagen synthesis
• D. Increases adhesion formation

Answer: (C)

During fibroplasia and consolidation, the wound is being filled in by fibroblasts that synthesize collagen to replace the granulation tissue and build strength. Mechanical tension across the wound acts as a signal to these fibroblasts, stimulating them to produce more collagen and to align the newly formed fibers in the direction of the pull. This organized deposition increases the tensile strength of the scar as remodeling proceeds. So the main effect of tension in this phase is to stimulate collagen synthesis, with collagen fibers preferentially oriented along the lines of tension rather than randomly arranged. While excessive tension can contribute to problems like widened scars or contractures, the direct impact described here is increased collagen production.
