General Information
Term dorsal transverse muscle cell ID (Ontology) FBbt:00000471 (Fly Anatomy)
Definition Any muscle cell (FBbt:00005074) that is part of some dorsal transverse muscle (FBbt:00058304).
Also Known As "DT1 muscle cell"
Comment Following Bate (1993), larval hypodermal muscles are named for their orientation and numbered based on their order from dorsal to ventral or anterior to posterior. So, except where musculature is essentially identical between segments (as for A1-7, with a couple of exceptions for A1), serial homology should not be assumed on the basis of a shared name.
