General Information
Term adult mesothoracic posterior dorsal commissure ID (Ontology) FBbt:00047540 (Fly Anatomy)
Definition Commissure formed from fibers of the anterior dorsal mesothoracic nerve projecting medially to the contralateral side of the mesothoracic neuromere (Power, 1948). Fibers that pass through this commissure may arborize in the posterior mesothoracic neuromere or the anterior metathoracic neuromere or join the contralateral mesothoracic accessory nerve or haltere nerve (Power, 1948). It is the dorsalmost commissure of the mesothoracic neuromere, and runs through the upper tectulum (Court et al., 2020). It develops from the larval mesothoracic posterior dorsal commissure and it contains the axons of hemilineage 6A (Court et al., 2020).[ FlyBase:FBrf0007196 FlyBase:FBrf0210897 FlyBase:FBrf0246815 ]
Also Known As "MesoNm PD" ; "PDD" ; "posterior dorsal mesothoracic decussation"
