larval LT1/LT2 motor neuron [FBbt_00110261]

Larval motor neuron that develops from NB2-2 and innervates the lateral transverse muscles 1 and 2 via type Ib boutons (Landgraf et al., 1997; Schmid et al, 1999; Hoang and Chiba, 2001; Kim et al., 2009). It has ipsilateral dendrites that extend anteriorly in the dorsolateral neuropil (Landgraf et al., 1997; Landgraf et al., 2003; Kim et al., 2009). Its axon fasciculates with the ipsilateral segmental nerve, innervating muscles of the same segment as its soma (Landgraf et al., 1997; Schmid et al, 1999; Hoang and Chiba, 2001; Kim et al., 2009).

Larva Motor neuron lineage 10 NB2-2 primary neuron

Larval motor neuron that develops from NB2-2 and innervates the lateral transverse muscles 1 and 2 via type Ib boutons (Landgraf et al., 1997; Schmid et al, 1999; Hoang and Chiba, 2001; Kim et al., 2009). It has ipsilateral dendrites that extend anteriorly in the dorsolateral neuropil (Landgraf et al., 1997; Landgraf et al., 2003; Kim et al., 2009). Its axon fasciculates with the ipsilateral segmental nerve, innervating muscles of the same segment as its soma (Landgraf et al., 1997; Schmid et al, 1999; Hoang and Chiba, 2001; Kim et al., 2009).

Identified as LT1-innervating in Landgraf et al. (1997), subsequent studies find only one LT1 neuron, which also innervates LT2 and has similar (ipsilateral and SNa) morphology (Hoang and Chiba, 2001; Kim et al., 2009).
