General Information
Term antennal grooming descending neuron 2 ID (Ontology) FBbt:00111648 (Fly Anatomy)
Definition Descending neuron whose cell body is located in the cell body rind posteroventrally to the gnathal ganglion (Hampel et al., 2015). The primary neurite extends dorsally to arborize broadly in the anterior antennal mechanosensory and motor center (AMMC) zones C and E and ventral subesophageal zone (SEZ) (Hampel et al., 2015). In the latter, the projections are more ventral than the ones of antennal grooming descending neuron 1 (Hampel et al., 2015). One neurite projects ventrally to exit the brain via the cervical connective and arborizes in the prothoracic neuromere (Hampel et al., 2015). There is one of these cells per hemisphere (Shiu et al., 2024). Its predicted neurotransmitter is acetylcholine (Eckstein et al., 2024).[ FlyBase:FBrf0229838 FlyBase:FBrf0259490 FlyBase:FBrf0260565 ]
Also Known As "aDN2" ; "DNge078"
Comment Mapped to DNge078 in Shiu et al. (2024) supplement.
