General Information
Term adult posterior dorsal mesothoracic nerve ID (Ontology) FBbt:00004061 (Fly Anatomy)
Definition A nerve that arises from the adult ventral nerve cord, just posterior to the root of the anterior dorsal mesothoracic nerve (Power, 1948; Court et al., 2020). It projects posteriolaterally before branching, with one branch innervating the tergal depressor of the trochanter (muscle 66), while the other branch forms further, terminal branches that innervate targets including the dorsal longitudinal indirect flight muscle (Power, 1948; Court et al., 2020).[ FlyBase:FBrf0007196 FlyBase:FBrf0246815 ]
