III1_MN [FBbt_00004069]

Motor neuron that innervates the muscle of third axillary 54 (III1), ipsilaterally (Trimarchi and Schneiderman, 1994). It has a teardrop-shaped soma, found ventral to the root of the accessory mesothoracic nerve, through which its axon exits the ventral nerve cord, and dorsal to the mesothoracic leg nerve (Trimarchi and Schneiderman, 1994). Within the ventral nerve cord, it has a large branch that forms arbors in the medial mesothoracic neuromere and a branch that projects anteriorly through the lateral mesothoracic neuromere (Trimarchi and Schneiderman, 1994). It remains predominantly ipsilateral, but some fibers may just reach the contralateral hemisphere (Trimarchi and Schneiderman, 1994; Ehrhardt et al., 2023).
