larval A1-7-innervating ISN motor neuron [FBbt_00110216]

Motor neuron that innervates the muscles of larval abdominal segments A1-7 and which fasciculates with the intersegmental nerve. Except for RP2 (dorsal motor neuron) their somas are located in the next anterior segment to the muscles they innervate (Zarin and Labrador, 2019). The dendritic domain of the motor neuron is located anteriorly to the dendritic domain of the motorneurons that innervate external muscles.

Larva Motor neuron Nervous system primary neuron

Motor neuron that innervates the muscles of larval abdominal segments A1-7 and which fasciculates with the intersegmental nerve. Except for RP2 (dorsal motor neuron) their somas are located in the next anterior segment to the muscles they innervate (Zarin and Labrador, 2019). The dendritic domain of the motor neuron is located anteriorly to the dendritic domain of the motorneurons that innervate external muscles.

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.
