SM FBbt:00110279 MN-VT1 A2-7 VT1 motor neuron fly_anatomy.ontology Larval motor neuron of the NB4-1 lineage that innervates the external ventral transverse muscle 1 (VT1), which is only found in A2 and more posterior segments (Landgraf et al., 1997; Zarin et al., 2019). It migrates medially and posteriorly during embryonic development (Schmid et al., 1999). Its dendritic domain is located posterior to the dendritic domain of the ISN motor neurons (Landgraf et al., 2003). It follows the transverse nerve and synapses to the VT1 muscle in the anterior part of the of the next posterior segment via type Ib boutons (Landgraf et al., 1997; Zarin et al., 2019). transverse nerve MN muscle cell of ventral transverse muscle 1 larval TN motor neuron larval transverse nerve root cell body rind of larval abdominal neuromere
