General Information
Term wing axillary muscle hg1 ID (Ontology) FBbt:00059070 (Fly Anatomy)
Definition Direct flight muscle that inserts into the fourth axillary (posterior notal wing process) and functions in carrying out lateral tip movements (Wisser and Nachtigall, 1984). It shares a tendon with the external muscle of fourth axillary hg4 (Williams and Williams, 1943). In contrast to most other wing muscles, hg1 is larger in males than in females, which is thought to allow for louder sine song (Shirangi et al., 2013). It is one of only two flight muscles that express doublesex (Shirangi et al., 2013).[ FlyBase:FBrf0006004 FlyBase:FBrf0098527 FlyBase:FBrf0223321 FlyBase:FBrf0239095 ]
Also Known As "external muscle of fourth axillary hg1" ; "posterior notal wing process muscle hg1"
