General Information
Term segment border muscle ID (Ontology) FBbt:00058316 (Fly Anatomy)
Definition Most internal of the larval lateral transverse muscles (Campos-Ortega and Hartenstein, 1997). It runs along the transverse apodeme at the segment boundary (Campos-Ortega and Hartenstein, 1997). It is an external muscle (Landgraf et al., 2003; Kohsaka et al., 2012).[ FlyBase:FBrf0064793 FlyBase:FBrf0089570 FlyBase:FBrf0167986 FlyBase:FBrf0218115 ]
Also Known As "SBM muscle"
Comment Here these muscles are considered to 'belong' to the anterior segment of the boundary each muscle runs along, i.e. mesothoracic SBM is between meso- and meta-thoracic segments.
