General Information
Term larval A1-7-innervating DO1 motor neuron ID (Ontology) FBbt:00002303 (Fly Anatomy)
Definition Larval DO1 motor neuron that innervates a muscle of segments A1-7. Its dendritic arborization occupies the lateral domains of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DO1 muscle of the next posterior segment to its soma with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001; Zarin and Labrador, 2019).[ FlyBase:FBrf0099344 FlyBase:FBrf0112030 FlyBase:FBrf0132289 FlyBase:FBrf0160715 FlyBase:FBrf0167986 FlyBase:FBrf0174847 FlyBase:FBrf0208790 FlyBase:FBrf0229965 FlyBase:FBrf0245882 ]
Also Known As "A1-7 MN-DO1 neuron" ; "A1-7 MN9-Ib" ; "A1-7 U1 motor neuron"
