General Information
Term larval lateral A1-7-innervating ISN motor neuron ID (Ontology) FBbt:00110218 (Fly Anatomy)
Definition Motor neuron that innervates the ventral and lateral ISN innervated muscles of larval abdominal segments A1-7. The dendritic domain of the motor neuron extends from the lateral to the intermediate regions.[ FlyBase:FBrf0160715 FlyBase:FBrf0208790 ]
Also Known As "ISN motor neuron of the intermediate neuropil of A1-7"
Comment The lateral, intermediate and medial neuropil fields follow a set of evenly distributed longitudinal fascicles that are labelled by anti-Fas2 antibody (Landgraf et al., 2003). The motor neuron MN-DA2, unlike other ISN motor neurons, has dendrites in the intermediate and lateral regions (Mauss et al., 2009).
