adult anterior dorsal mesothoracic nerve

ID: FBbt_00004060

The largest and anterior-most of the two dorsal mesothoracic nerves (Power, 1948; Court et al., 2020). It extends dorso-anteriorly from the ventral nerve cord and then dorso-laterally, bending around the anterior face of the anterior tergosternal muscles before splitting into branches that innervate the lateral muscles near the body wall, beneath the base of the wing (Power, 1948). It also sends a branch between the anterior tergosternal muscles (Power, 1948). As well as the coarse motor fibers, this nerve also carries fine sensory fibers from the wing (Power, 1948).
