Question

Quizplus · Accepted Answer

During development, many myoblasts fuse to form a muscle fiber with more than one nucleus. This process is known as myogenesis and results in the formation of multinucleated muscle fibers. These fibers contain many myofibrils, which are composed of bundles of filaments that slide past one another during muscle contractions. Osteoblasts, on the other hand, are bone-forming cells and are not involved in the development of skeletal muscle fibers.
