larval A1-7-innervating DO4 motor neuron [FBbt_00110240]

Larval motor neuron that innervates the internal dorsal oblique muscle 4 (DO4) in larval abdominal segments A1 to A7. It develops from neuroblast NB3-2 (Landgraf et al., 1997. Its dendritic arborization occupies the lateral domain of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DO4 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001. These neurons (at least in A1 to A4) die during metamorphosis (Banerjee et al., 2016. Its soma is located in the segment anterior to the muscle innervated (Kohsaka et al., 2012. (Hoang and Chiba, 2001, Banerjee et al., 2016, Landgraf et al., 2003, Kohsaka et al., 2012, Landgraf et al., 1997, Mauss et al., 2009, Schmid et al., 1999, Choi et al., 2004, Landgraf et al., 2003)

Larval motor neuron that innervates the internal dorsal oblique muscle 4 (DO4) in larval abdominal segments A1 to A7. It develops from neuroblast NB3-2 (Landgraf et al., 1997. Its dendritic arborization occupies the lateral domain of the ventral nerve cord neuropil.

There is little or no published literature specifically on innervation in A1 and so where equivalent muscles are present between A1 and A2-7 (Landgraf et al., 1997; Schmid et al., 1999, we infer A1 motor neuron innervation patterns from those of A2-7.
