part of innervates continuous with develops from adult anterior dorsal mesothoracic nerve adult mesothoracic accessory nerve adult dorsal metathoracic nerve adult mesothoracic posterior dorsal commissure 2018-08-10T13:19:06Z 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).
