Now known to correspond to U3 (Zarin et al., 2019; Meng et al., 2019). FBbt:00001567 U3 motor neuron MN2-Ib Larval motor neuron that innervates dorsal acute muscle 2 (muscle 2) via type Ib synapses (Landgraf et al., 1997; Hoang and Chiba, 2001; Meng et al., 2019). It is the third-born U neuron, developing from the third ganglion mother cell that differentiates from neuroblast NB7-1 (Cleary and Doe, 2006; Seroka et al., 2020). It has a monopolar morphology and its dendrites remain ipsilateral (Seroka and Doe, 2019; Meng et al., 2019). motor neuron ganglion mother cell GMC7-1c type Ib motor neuron larval internal muscle motor neuron muscle cell of dorsal acute muscle 2 unilateral
