Regarding the regenerative capacity of muscle tissues following injury, which statement most accurately reflects their comparative biological potential?

A. Cardiac muscle regenerates readily via satellite cells
B. Skeletal muscle has limited regenerative capacity through satellite cells
✓
C. Smooth muscle lacks the ability to undergo mitosis and regenerate
D. All three muscle types possess equal hypertrophic and hyperplastic abilities

📝 Explanation

Skeletal muscle can undergo limited repair via satellite cells. Smooth muscle has the greatest regenerative capacity and can undergo both hypertrophy and hyperplasia. Cardiac muscle has virtually no regenerative capacity, typically replacing damaged tissue with non-contractile fibrous scar tissue.
