What are the cell components of skeletal muscle?

Skeletal muscle is primarily composed of muscle fibers, which are long, cylindrical cells that contain multiple nuclei. These fibers are packed with myofibrils, which are further made up of repeating units called sarcomeres that contain actin and myosin filaments, responsible for contraction. Additionally, skeletal muscle contains satellite cells for repair and regeneration, as well as connective tissue components such as endomysium, perimysium, and epimysium that support and protect the muscle fibers. Mitochondria are also abundant in these cells to provide the energy needed for muscle activity.
