General Information
Term descending neuron outside of the brain DNx01 ID (Ontology) FBbt:00047669 (Fly Anatomy)
Definition Descending neuron belonging to the DNx group, having a cell body outside of the brain (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 wedge, gnathal ganglion, intermediate tectulum, lower tectulum, abdominal neuromere, T1 leg neuropil and T2 leg neuropil (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 a sensory neuron (Sturner et al., 2024).[ FlyBase:FBrf0239335 ]
Also Known As "DNx01" ; "DNxn051"
Comment Namiki et al. (2018), identify this as being morphologically similar to the sensory cell of the large campaniform sensillum, described by Nassel et al. (1984) (FBrf0239831).
