larval LT3/LT4 motor neuron [FBbt_00110270]

Larval motor neuron that develops from NB3-2 and innervates the lateral transverse muscles 3 and 4 via type Ib boutons (Landgraf et al., 1997; Schmid et al, 1999; Hoang and Chiba, 2001; Wang et al., 2022). It arborizes in the ipsilateral neuropil, and 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).

Larva Motor neuron lineage 7 NB3-2 primary neuron

Larval motor neuron that develops from NB3-2 and innervates the lateral transverse muscles 3 and 4 via type Ib boutons (Landgraf et al., 1997; Schmid et al, 1999; Hoang and Chiba, 2001; Wang et al., 2022). It arborizes in the ipsilateral neuropil, and 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).

Identified as LT4-innervating in Landgraf et al. (1997), subsequent studies find only one LT4 neuron, which also innervates LT3 and has similar (ipsilateral and SNa) morphology (Hoang and Chiba, 2001; Wang et al., 2022).
