b1_MN [FBbt_00004066]

Motor neuron that innervates the direct flight muscle 49 (b1) ipsilaterally (Trimarchi and Schneiderman, 1994). It has a large disk-shaped soma, found ventral to the root of the anterior dorsal mesothoracic nerve, through which its axon leaves the ventral nerve cord (Trimarchi and Schneiderman, 1994). It has a large posterior branch that projects into and arborizes within the root of the dorsal metathoracic (haltere) nerve (Trimarchi and Schneiderman, 1994). It also has a large branch that crosses the midline and arborizes in the contralateral lateral wing neuropil (Trimarchi and Schneiderman, 1994). Two smaller branches arborize in the dorsal and lateral ipsilateral wing neuropil (Trimarchi and Schneiderman, 1994). It is required for normal coordination of wing movement during flight (Sadaf et al., 2015).
