Its primary neurite branches in the M2 layer, in the same sublayer as Dm14 and Dm17. The arbor is very large, covering 100-200 columns. The majority of processes are located in a central columnar position, similar to Dm6. There are around 15 Dm19 neurons per hemisphere. Dm19 FBbt:00111280 fly_anatomy.ontology
