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 DA1 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001). By embryonic stage 16, it has a short contralaterally projecting neurite extending into the posterior commissure. abdominal aCC neuron A1-7 aCC motor neuron A1-7 MN1-Ib FBbt:00110220 VFB:FBbt_00110220 A1-A7 MN-DA1 fly_anatomy.ontology A1-7 aCC neuron bilateral
