This chapter describes the structure, chemistry, and function of skeletal muscle. Individual skeletal muscles are well formed by the 10th week of gestation, and in the next 6 weeks, myotubes proliferate by fusio
which remain in a quiescent and undifferentiated state, can enter the mitotic circle. This induces proliferation and fusion of myoblasts to form multinucleated and elongated myotubes that self-assemble to form a more organized structure, namely muscle fiber[2]. Satellite cells migrate and proliferate...

Muscle Fiber Architecture Single skeletal muscle fibers are elongated, multinucleated cells that have variable lengths and shapes. A fiber is comprised of a number of myofibrils arranged in parallel and comprised of sarcomeres arranged in-series. Asarcomere, in turn, is comprised of myofilaments, ...
muscle fiber can be up to 100μm, so these T-tubules ensure that the membrane can get close to the SR in the sarcoplasm. The arrangement of a T-tubule with the membranes of SR on either side is called atriad(Figure 5). The triad surrounds the cylindrical structure called amyofibril,...
There are 3 types of muscle: skeletal muscle,cardiac muscle, and smooth muscle. Each of these has a different structure and role. While skeletal muscle attaches toyour bonesand helps you move, cardiac muscle is the muscle fibers of your heart and responsible for its pumping action. Smooth mus...
