Muscle fibres: range in diameter from 10-120um. Individual muscle fibres attach to the bone through the tendon. Satellite cells: located between the plasmalemma and the basement membrane. Involved in growth and development of the skeletal muscle and in the muscle adaptation to injury, immobilization and training.
