What do myofibroblast cells do fascia sometimes?

• A. Makes fascia tight, which can cause restrictions or joint adhesions
• B. Increases fascia elasticity
• C. Decreases tissue stiffness
• D. Promotes fascia tearing

Answer: (A)

Myofibroblasts are specialized fibroblasts that gain smooth muscle–like contractile ability. When they are present in fascia, they pull on the surrounding extracellular matrix, generating tension and tightening the fascia. This tightening can create fascial restrictions and adhesions between layers or around joints, which can limit movement. They tend to increase tissue stiffness rather than elasticity, and their primary effect isn’t tearing—though excessive tension can contribute to injury if the tissue is stressed. So the best description is that these cells make fascia tight, leading to potential restrictions.
