Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person's body weight. The muscular system starts taking shape when the embryo is just a flat little pancake made up of two layers: the epiblast on the dorsal, or back, side, and the hypoblast on the ventral, or front, side. Muscle fibers form from the fusion of myoblasts into multi-nucleated fibers called myotubes. The mesoderm forms nearly all the connective tissues of the musculoskeletal system. The muscular system is one component of the musculoskeletal system, which includes not only the muscles but also the bones, joints, tendons, and other structures that permit movement. Biotechnol.

In addition, development of the musculoskeletal system is complicated by the different embryological origins of the various musculoskeletal components. Myogenesis is the formation of muscular tissue, particularly during embryonic development. The muscular system develops from mesoderm, except for the muscles of the iris of the eye, which develop from neuroectoderm (neural crest cells), and the muscles of the esophagus, which are thought to develop by transdifferentiation from smooth muscle.Myoblasts (embryonic muscle cells) are derived from mesenchyme (embryonic connective tissue). Avian pelvis originates from lateral plate mesoderm and its development requires signals from both ectoderm and paraxial mesoderm. Extraembryonic mesoderm lies adjacent to the trilaminar embryo totally enclosing the amnion, yolk sac and forming the connecting stalk.
