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.
