larval A1-7-innervating DA2 motor neuron

ID: FBbt_00002311

Larval DO1 motor neuron that innervates a muscle of segments A1-7. Its dendritic arborization occupies the lateral and intermediate domains of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DA2 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001. The muscle it innervates is one segment posterior to its soma (Zarin and Labrador, 2019. (Landgraf et al., 2003, Hoang and Chiba, 2001, Heckscher et al., 2015, Zarin and Labrador, 2019, Landgraf et al., 1997, Mauss et al., 2009, Zarin et al., 2019, Choi et al., 2004, Landgraf et al., 2003, Schmid et al., 1999)

This motor neuron is an exception to the class of motorneurons that innervate the internal dorsal muscles whose dendrites occupy the lateral neuropil; it has dendrites in the intermediate and lateral regions (Mauss et al., 2009. Previously thought to correspond to the U2 neuron based on personal communication from Matthias Landgraf - FBrf0221138, but shown to be U3 by Meng et al., 2019.
