How are myotubes formed during muscle development?
Myotubes are formed during muscle development through a process called myogenesis. Myogenesis is the formation of muscle tissue from precursor cells called myoblasts. These myoblasts fuse together to form long, multinucleated cells called myotubes, which eventually mature into muscle fibers. This process is regulated by various signaling molecules and transcription factors that control the differentiation and fusion of myoblasts into myotubes.
