General Information
Term descending neuron of the gnathal ganglion DNg29 ID (Ontology) FBbt:00047621 (Fly Anatomy)
Definition Descending neuron belonging to the DNg group, having a cell body in the cell body rind around the gnathal ganglion (Namiki et al., 2018). It descends on the ipsilateral side of the cervical connective, but also has contralateral innervation (Namiki et al., 2018). It has neurites in the saddle, antennal mechanosensory and motor center, anterior ventrolateral protocerebrum, wedge, gnathal ganglion and lower tectulum (Namiki et al., 2018). It fasciculates with the dorsal lateral tract of the ventral cervical fascicle in the ventral nerve cord (Namiki et al., 2018). There is one of these cells per hemisphere (Namiki et al., 2018). It is cholinergic (Cheong et al., 2024).[ FlyBase:FBrf0239335 ]
Also Known As "DNg29" ; "DNxn022"
Comment Namiki et al. (2018), identify this as being morphologically similar to the antennal mechanosensory and motor center Db7 neuron (FBbt:00111502), described by Matsuo et al. (2016) (FBrf0230862).
