Its dendritic arborization occupies the lateral domain of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DA3 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001). Its soma is in the segment anterior to the muscle it innervates (Kohsaka et al., 2012). A1-7 MN3-Ib FBbt:00110233
