Definition Thin commissure of a few fibers (Power, 1948) that is derived from the larval mesothoracic anterior ventral commissure, which becomes segregated into two (anterior and posterior) adult commissures (Court et al., 2020). It is formed by primary neurite bundles of hemilineage 1A (Court et al., 2020). It is found at the ventralmost margin of the mesothoracic neuromere, outside of the cell body rind, at the anterior of the neuromere (Court et al., 2020).[ FlyBase:FBrf0007196 FlyBase:FBrf0246815 ]
