General Information
Term larval abdominal ventral multidendritic neuron v'td2 ID (Ontology) FBbt:00002581 (Fly Anatomy)
Definition Tracheal associated multidendritic neuron of the ventral' cluster of segments A1-7 (Qian et al., 2018). In A1-6 it is located dorsal to v'td1, in A7 it is the only type of ventral tracheal dendrite neuron (Qian et al., 2018). Like other neurons of this cluster, it follows the SNa branch of the segmental nerve (Williams and Shepherd, 1999). After entering the ventral nerve cord, it projects anteriorly, with neurons of more anterior segments (A1-A3) reaching the subesophageal zone and more posterior neurons terminating in the vicinity of the metathoracic neuromere (Qian et al., 2018). It expresses gustatory receptors, indicating that it may be chemosensory (Qian et al., 2018).[ FlyBase:FBrf0089570 FlyBase:FBrf0108300 FlyBase:FBrf0238188 ]
Also Known As "larval abdominal ventral multidendritic neuron vtd2"
Comment Sometimes both v'td neurons in a hemisegment are collectively referred to as v'td2, as in Williams and Shepherd (1999).
