3-2Mar [FBbt_00001549]

Any larval motor neuron that develops from NB3-2 and fasciculates with the intersegmental nerve, exiting the ventral nerve cord via the anterior root. According to Schmid et al. (1999) there are 4 motorneurons which project to muscles: DA2, DO2, DO3, DO4 and DO5. According to Landgraf et al. (1997), the 4 motorneurons innervate: DO3-5 and DT1.

7-1M [FBbt_00001558]

Any embryonic/larval motor neuron (FBbt:00007675) that develops from some neuroblast NB7-1 (FBbt:00001380). According to Landgraf et al. (1997) and Schmid et al. (1999), several motorneurons are produced from NB7-1: MN-DA2/DA3, MN-DO1/DO2, MN-LL1, MN-VO4-6 and MN-VO4/5. This term was obsoleted because neurons classes were made for each of these motorneurons.

A1-7 DA1 motor neuron [FBbt_00110220]

Motor neuron that innervates the internal dorsal acute muscle 1 of larval abdominal segments A1 to A7. Its dendritic arborization occupies the lateral domain of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DA1 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001). By embryonic stage 16, it has a short contralaterally projecting neurite extending into the posterior commissure. It receives input from the contra- and ipsilateral larval A27h neuron. 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. These neurons were identified in a EM reconstruction of a volume that includes the posterior half of abdominal segment 2 and abdominal segment 3, of a 12-24h old first instar larva. The number of connections was estimated from the publication figures. The number of input synapses was the following (number in brackets ipsilateral/contralateral): from A27h (10/10) (Schneider-Mizell et al., 2016).

A1-7 DA2 motor neuron [FBbt_00002311]

Motor neuron that innervates the internal dorsal acute muscle 2 of larval abdominal segments A1 to A7 (Landgraf et al., 1997). 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). 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. 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). Based on cell body position, the DA2 motor neuron appears to correspond to the U2 neuron (personal communication by Matthias Landgraf - FBrf0221138), however, Zarin et al. (2019) report that the DA2 motor neuron corresponds to U3.

A1-7 DA3 motor neuron [FBbt_00110233]

Motor neuron developing from the fourth ganglion mother cell that differentiates from neuroblast NB7-1. It innervates the internal dorsal acute muscle 3 (DA3) of larval abdominal segments A1 to A7. Its dendritic arborization occupies the lateral domain of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DA3 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001). Its soma is in the segment anterior to the muscle it innervates (Kohsaka et al., 2012). 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. The DA3 motor neuron is likely to correspond to the U4 neuron. This is suggested by the cell body position and by extrapolating the observation that these neurons that extend their axons the furthest differentiate the earliest (personal communication by Matthias Landgraf - FBrf0221138).

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. Based on cell body position, the DO1 motor neuron corresponds to the U1 neuron (personal communication by Matthias Landgraf - FBrf0221138).

A1-7 DO3 motor neuron [FBbt_00110237]

Motor neuron that develops from the neuroblast NB3-2 lineage (Landgraf et al., 1997). It innervates the internal dorsal oblique muscle 3 (DO3) of larval abdominal segments A1 to A7. Its dendritic arborization occupies the lateral domain of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DO3 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001). These neurons (at least in A1 to A4) die during metamorphosis (Banerjee et al., 2016). Its soma is in the segment anterior to the muscle it innervates (Kohsaka et al., 2012). 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.

A1-7 DO5 motor neuron [FBbt_00110241]

Motor neuron that develops from the neuroblast NB3-2 lineage (Landgraf et al., 1997; Schmid et al., 1999). It innervates the internal dorsal oblique muscle 5 (DO5) of larval abdominal segments A1 to A7. Its dendritic arborization occupies the lateral domain of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DO5 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001). These neurons (at least in A1 to A4) die during metamorphosis (Banerjee et al., 2016). Its soma is found in the segment anterior to the muscle it innervates (Kohsaka et al., 2012). Muscle DO5 is only present in A1-7. 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.

A1-7 dorsal motor neuron [FBbt_00002207]

Motor neuron that innervates the internal dorsal acute, dorsal oblique and LL1 muscles of larval abdominal segments A1 to A7 (Landgraf et al., 2003). It exits the ventral nerve cord via the posterior root of the intersegmental nerve. It is one of the common exciters of the A1-7 muscles, innervating the dorsal and LL1 muscles via type Is boutons (Mauss et al., 2009). It receives input from the ipsilateral larval A02b, A27j, eIN-4 (A03a1) and A27e and contralateral larval A08e1-3 local neurons and A31k neuron. Unlike other ISN neurons, its soma is located in the same segment as the muscles it innervates (Zarin and Labrador, 2019). 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. These neurons were identified in one EM reconstruction of abdominal segment 3 of a 12-24h old first instar larva (Heckscher et al., 2015; Schneider-Mizell et al., 2016). For Heckscher et al. (2015) only bilateral connections are reported. The number of identified input synapses was the following (number in brackets left/right): from A08e1 (1-4/1-7), A08e2 (1-4/1-7), A08e3 (1-4/1-7) (Heckscher et al., 2015). For Schneider-Mizell et al. (2016), the number of connections was estimated from the publication figures. The number of input synapses was the following (number in brackets left/right where available): from A02b (12/12), A27j (12/25), A03a1 (20/23), A27e (21), A31k (35/35) (Schneider-Mizell et al., 2016).

A1-7 dorsal VUM motor neuron [FBbt_00002239]

Neuromodulatory motor neuron that innervates the internal dorsal acute and oblique muscles of larval abdominal segments A1 to A7 via type II boutons. It exits the ventral nerve cord via the posterior root of the intersegmental nerve and fasciculates with the ISNb or ISNd intersegmental nerve branches. These neurons have a virtually identical arborization pattern, shared with the lateral and ventral VUM neurons of A1-7. They arborize along and dorsal to the dorsal median fascicle and laterally along the dorsal lateral fascicle, invading the next anterior neuromere. In the dorsomedial neuropil, arborizations are sent into at least two (usually three) anterior neuromeres and the adjacent posterior neuromere (Selcho et al., 2012). 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.

A1-7 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 innervated (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). Following Landgraf et al., 1997, larval motor neurons are named according to the muscle they innervate. The same caveats therefore apply regarding inference of serial homology from nomenclature as for the muscles: Following Bate (1993), larval hypodermal muscles are named for their orientation and numbered based on their order from dorsal to ventral or anterior to posterior. So, except where musculature is essentially identical between segments (as for A1-7, with a couple of exceptions for A1), serial homology should not be assumed on the basis of a shared name.

A1-7 lateral VUM motor neuron [FBbt_00002255]

Neuromodulatory motor neuron that innervates the lateral transverse muscles of larval abdominal segments A1 to A7 via type II boutons.

In A2-7, these might also synapse to muscles 26 (VA1), 27 (VA2) and 29 (VA3) (Selcho et al., 2012).

Its soma is found in the segment anterior to the muscle it innervates (Kohsaka et al., 2012). 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. The LL1 motor neuron is likely to correspond to the U5 neuron. This is suggested by the cell body position and by extrapolating the observation that these neurons that extend their axons the furthest differentiate the earliest (personal communication by Matthias Landgraf - FBrf0221138).

abdominal 1 VL1 motor neuron [FBbt_00047502]

Motor neuron that innervates ventral longitudinal muscle 1 (VL1; muscle 12), in larval abdominal segment A1, via type Ib boutons (Hoang and Chiba, 2001). Its cell body is located contralateral to VL1 and it fasciculates with the ISNb nerve branch (Hoang and Chiba, 2001). During metamorphosis, its target muscle, VL1, develops into a temporary eclosion muscle, with some remodeling of the neuron, and this neuron becomes adult persistent motor neuron 12-Ib A1 (Banerjee et al., 2016). 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.
