General Information
Term wing basalar muscle b2 motor neuron ID (Ontology) FBbt:00004068 (Fly Anatomy)
Definition Motor neuron that innervates the basalar muscle 51 (b2), ipsilaterally (Trimarchi and Schneiderman, 1994). It has a roughly spherical soma, located ventral to the root of the posterior dorsal mesothoracic nerve (Trimarchi and Schneiderman, 1994). Its axon exits the ventral nerve cord in the anterior dorsal mesothoracic nerve (Trimarchi and Schneiderman, 1994). Within the ventral nerve cord, one branch projects medially and arborizes in the anterior and medial wing neuropil, without crossing of the midline (Trimarchi and Schneiderman, 1994; Ehrhardt et al., 2023). A group of projections also extends posteriorly, arborizing in the dorsal metathoracic (haltere) nerve root and the dorsal mesothoracic leg neuropil (Trimarchi and Schneiderman, 1994). Other branches reach dorsal and lateral parts of the ipsilateral wing neuropil (Trimarchi and Schneiderman, 1994).[ FlyBase:FBrf0074636 ]
Also Known As "b2 MN" ; "b2_MN" ; "b2mn"
