General Information
Term somatic muscle primordium ID (Ontology) FBbt:00005518 (Fly Anatomy)
Definition Primordium of the embryonic/larval somatic musculature. It arises from the outer layer of the mesoderm. During germ band shortening (stage 13), it segregates into loose segmental clusters. Within these clusters, muscle formation proceeds by fusion of fusion competent myoblasts to muscle founder cells. Formation of the embryonic/larval somatic musculature is complete by stage 17.[ FlyBase:FBrf0064793 FlyBase:FBrf0064803 FlyBase:FBrf0089570 ]
