During the proliferation stage, which item is being formed?

• A. Bone
• B. Muscle
• C. Nerve fibers
• D. Scar tissue

Answer: (D)

The main idea here is that the proliferation stage builds new tissue to fill a wound by laying down collagen and forming granulation tissue, which later becomes scar tissue. Fibroblasts migrate into the wound and synthesize extracellular matrix, especially collagen, creating a scaffold that supports new tissue growth and wound closure. This collagen-rich tissue is what we call scar tissue as the wound matures and remodels. Bone formation isn’t the focus of this stage; that occurs during bone healing with osteogenesis. Nerve fibers and muscle tissue aren’t the primary products of proliferation in typical soft-tissue healing—their restoration isn’t the main event of this phase.
