DA3 motor neuron [FBbt_00110231]

Any motor neuron (FBbt:00005123) that synapsed via type Ib bouton to some dorsal acute muscle 3 (FBbt:00110232). Following Landgraf et al., 1997, larval motor neurons are named according to the muscle they innervate. The same caveats therefore apply regarding inference of serial homology from nomenclature as for the muscles: Following Bate (1993), larval hypodermal muscles are named for their orientation and numbered based on their order from dorsal to ventral or anterior to posterior. So, except where musculature is essentially identical between segments (as for A1-7, with a couple of exceptions for A1), serial homology should not be assumed on the basis of a shared name. The DA3 motor neuron is likely to correspond to the U4 neuron. This is suggested by the cell body position and by extrapolating the observation that these neurons that extend their axons the furthest differentiate the earliest (personal communication by Matthias Landgraf).
