It fasciculates with the posterior dorsal mesothoracic nerve, extends ventrally and medially, bifurcates and follows the main course of the pathway anteriorly, reaching the prothoracic neuromere, and posteriorly, up to the bifurcation of the posterior crossbranch. The main crossbranch extends contralaterally. VFB:FBbt_00111219 FBbt:00111219 fly_anatomy.ontology sensory perception detection of mechanical stimulus bilateral
