General Information
Term maxillary anterior commissure ID (Ontology) FBbt:00047891 (Fly Anatomy)
Definition Any larval anterior commissure (FBbt:00001105) that is part of some larval maxillary neuromere (FBbt:00001975).[ FlyBase:FBrf0237252 ]
Also Known As "aIMX" ; "anterior intermediate commissure of maxillary neuromere" ; "ISA" (for all, see Synonyms field below)
Comment Hartenstein et al. (2018) say this (and not other mandibular/maxillary commissures) can be distinguished at later stages of development, and also show only one (intermediate) anterior commissure in the maxillary neuromere, so this is probably the intermediate anterior subesophageal (ISA) commissure of Kuert et al. (2014) - https://orcid.org/0000-0002-1373-1705.
