General Information
Term trunk visceral muscle primordium ID (Ontology) FBbt:00005519 (Fly Anatomy)
Definition Primordium that is derived from the trunk mesoderm and produces larval visceral musculature (Campos-Ortega and Hartenstein, 1997). This produces all of the visceral muscle except for that of the esophagus (Campos-Ortega and Hartenstein, 1997; de Velasco et al., 2006).[ FlyBase:FBrf0089570 FlyBase:FBrf0190261 ]
