General Information
Term larval A1-7-innervating VL2 motor neuron ID (Ontology) FBbt:00110292 (Fly Anatomy)
Definition Motor neuron of the larva that synapses to the ventral longitudinal muscle 2 (muscle 13) of A1-7 with a type Ib bouton. Its cell body is ipsilateral to the target muscle at the distal edge of the CNS (Hoang and Chiba, 2001; Kohsaka et al., 2015). It fasciculates with the intersegmental nerve branch b (ISNb), which also contains other neurons that innervate ventrolateral internal muscles (Kohsaka et al., 2015). It innervates the muscle of the segment immediately posterior to its soma (Kohsaka et al., 2015). During metamorphosis, this neuron (at least in neuromeres T3-A3) switches targets and becomes adult persistent motor neuron 13-Ib (Banerjee et al., 2016).[ FlyBase:FBrf0064795 FlyBase:FBrf0112030 FlyBase:FBrf0132289 FlyBase:FBrf0208790 FlyBase:FBrf0218115 FlyBase:FBrf0234013 ]
