General Information
Term wing axillary muscle hg2 motor neuron ID (Ontology) FBbt:00048111 (Fly Anatomy)
Definition Motor neuron that innervates the internal muscle of the fourth axillary 58b (hg2), ipsilaterally (Ehrhardt et al., 2023). Within the ventral nerve cord, it arborizes in the dorsal mesothoracic neuropil, including the wing neuropil, with greater innervation of the contralateral side (O'Sullivan et al., 2018; Ehrhardt et al., 2023). In the male, it plays a role in pulse and sine song generation (O'Sullivan et al., 2018; Ehrhardt et al., 2023).[ FlyBase:FBrf0240039 ]
Also Known As"hg2 MN" ; "hg2_MN" ; "wing axillary muscle iv2 motor neuron"
