Question

Quizplus · Accepted Answer

Muscle repair is primarily due to the activation of satellite cells, which are a type of muscle stem cell located outside of muscle fibers. Upon activation, satellite cells will proliferate and differentiate into myoblasts, which then fuse to form new muscle fibers or myotubes. Myofibrils and muscle cells are not directly involved in the repair process.
