part of oblique muscle cell muscle cell of lateral oblique muscle 1 LO1 muscle cell Any muscle cell (FBbt:00005074) that is part of some lateral oblique muscle 1 (FBbt:00058301). fly_anatomy.ontology FBbt:00000468 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. Classed as external in Kohsaka et al. (2012) and Landgraf et al. (2003) (and, consistently, is innervated by the SN), but classed as internal by Zarin and Labrador (2019) - FBrf0245882. muscle cell larval external muscle cell lateral oblique muscle 1
