Which sequence correctly lists the phases of tendon healing in order?

The sequence tested is about the timing of tendon healing phases. After injury, the inflammatory phase begins first to stop bleeding, clear debris, and summon cells that set the stage for repair. Next comes the restorative (proliferative) phase, where fibroblasts produce collagen and extracellular matrix to bridge the tendon ends and form granulation tissue. Finally, the remodeling phase restructures the new tissue, aligning collagen along the tendon’s direction and increasing tensile strength as type III collagen is replaced by stronger type I collagen. Because tissue must be cleaned and a scaffold laid down before repair, and the repair tissue must be laid down before it can be remodeled, the correct order is inflammatory, restorative, remodeling. Starting with any later phase would skip essential early steps, and placing remodeling before restorative skips the formation of the initial repair tissue.
