General Information
Term fronto-tentorial muscle 19a ID (Ontology) FBbt:00058810 (Fly Anatomy)
Definition A temporary eclosion muscle that connects the tentorium to the frons. It arises from the same tendons of the tentorium and occipital sclerites though more centrally than the geno-tentorial muscles 19b. They are inserted in large dorsoventral groups on the lateral margins of the fronto-clypeus. Contraction of these muscles causes the head volume to decrease. As with other temporary eclosion muscles, it degenerates 72h after adult emergence.[ FlyBase:FBrf0007310 FlyBase:FBrf0186027 ]
Also Known As "fronto-tentorial muscle"
