Development of Muscles

Development of Muscle 5 processes in the formation of a muscle. 1. the direction of the muscle is altered. - rhomboid muscles 2. fusion of segments of successive myotomes - erector spinae muscle. 3. muscles migrate long distances - latissimus dorsi 4. myotomes can split into more than one muscle. trapezius and sternocleidomastoid. 5. degeneration of parts of the muscle with the conversion of the degenerated portions into connective tissue.
