part of ventral longitudinal muscle cell muscle cell ventral longitudinal muscle 3 muscle cell of ventral longitudinal muscle 3 2013-01-17T05:05:10Z Any muscle cell (FBbt:00005074) that is part of some ventral longitudinal muscle 3 (FBbt:00059138). FBbt:00110246 VL3 muscle cell 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. fly_anatomy.ontology
