General Information
Term larval DO5 motor neuron ID (Ontology) FBbt:00110241 (Fly Anatomy)
Definition Larval motor neuron that innervates the internal dorsal oblique muscle 5 (DO5), which is found only in larval abdominal segments A1 to A7. It develops from neuroblast NB3-2 (Landgraf et al., 1997; Schmid et al., 1999). 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 DO5 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001). These neurons (at least in A1 to A4) die during metamorphosis (Banerjee et al., 2016). Its soma is found in the segment anterior to the muscle it innervates (Kohsaka et al., 2012).[ FlyBase:FBrf0064795 FlyBase:FBrf0099344 FlyBase:FBrf0112030 FlyBase:FBrf0132289 FlyBase:FBrf0160715 FlyBase:FBrf0167986 FlyBase:FBrf0174847 FlyBase:FBrf0208790 FlyBase:FBrf0218115 FlyBase:FBrf0234013 ]
