General Information
Term larval internal muscle motor neuron ID (Ontology) FBbt:00051430 (Fly Anatomy)
Definition Larval motor neuron (MN) that innervates an internal muscle (Landgraf et al., 2003). They tend to follow the intersegmental nerve and have dendritic arborizations in the next anterior neuromere to the target muscle, with ventral muscle MNs most anterior, then dorsal, then lateral muscle MNs (Landgraf et al., 2003).[ FlyBase:FBrf0167986 ]
