Term costal nerve ID (Ontology) FBbt:00100123 (Fly Anatomy)
Definition Nerve that travels through the medial costal vein of the proximal anterior wing margin (Palka et al., 1979), it remains distinct from the combined L1-L3 nerve until both nerves leave the wing via the anterior dorsal mesothoracic nerve (Murray et al., 1984). It is composed of axons collected from the marginal sensilla of the distal, medial and proximal costa, as well as the tegula (Palka et al., 1979).[ FlyBase:FBrf0032909 FlyBase:FBrf0040724 FlyBase:FBrf0073164 ]
