has soma location develops from neuroblast MP2 dMP2 neuron fly_anatomy.ontology VFB:FBbt_00001602 Primary neuron that differentiates from neuroblast MP2 and projects posteriorly (Thomas et al., 1984). Axons from dMP2 neurons innervate the hindgut, forming two fascicles that extend on opposite sides of the hindgut (Miguel-Aliaga et al., 2008). By the adult stage, arbors have formed that innervate the anterior intestines and the rectum. dMP2 neurons perform a pioneer function in embryos then undergo apoptosis in all but segments A6-A9 (Miguel-Aliaga et al., 2008).
