larval A1-7-innervating DT1 motor neuron [FBbt_00110278]

Motor neuron developing from neuroblast NB3-2 lineage that innervates the dorsal transverse muscle 1 (DT1) of abdominal segments 1 to 7 (Landgraf et al., 1997). It exits the ventral nerve cord via the anterior intersegmental nerve root, fasciculates with the intersegmental nerve, and innervates the DT1 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001). Although it innervates an external muscle, its soma is clustered with those of the internal muscle-innervating neurons in the segment anterior to the muscle it innervates (Landgraf et al., 2003). Its dendritic arborizations are found with those of other external muscle-innervating neurons, connected via a long posterior projection (Landgraf et al., 2003).
