General Information
Term adult prothoracic neuromere ID (Ontology) FBbt:00110174 (Fly Anatomy)
Definition Anteriormost of the four major neuropils that makes up the adult ventral nerve cord (VNC) (Court et al., 2020). It is mostly composed of the somata and projections of central neurons derived from the prothoracic array of neuroblasts and the axonal projections of sensory afferents from the prothoracic legs and prothorax (Court et al., 2020). It is a bilaterally paired neuropil that exists as two more or less spherical masses (Court et al., 2020). Its anterior boundary defines the anterior extent of the VNC (Court et al., 2020). The posterior boundary can be defined by the extent of the primary neurite projections of the central neurons produced by the prothoracic neuroblasts 0, 3, 6, 11, 21, 20/22 and 23 (Court et al., 2020). Dorsal nerves that directly innervate the neuropil of the prothoracic neuromere (dorsal prothoracic nerve, prosternal nerve, prothoracic chordotonal nerve, prothoracic accessory nerve and ventral prothoracic nerve) emerge closely adjacent to each other in the anteriolateral corner of the prothoracic neuromere and sometimes appear to share a common exit point (Court et al., 2020).[ FlyBase:FBrf0246815 ]
