General Information
Term dorsal organ ID (Ontology) FBbt:00002655 (Fly Anatomy)
Definition An external compound sense organ of the antenno-maxillary complex of the larval head consisting of two sensilla, a dome shaped cuticular process, and a region surrounding the base of the dome (Campos-Ortega and Hartenstein, 1997; Komarov and Sprecher, 2022). The dome sensillum is innervated by seven circularly arranged triplets of olfactory receptor neuron dendrites (Komarov and Sprecher, 2022). Sensory neurons of other modalities innervate the base sensillum (Komarov and Sprecher, 2022).[ FlyBase:FBrf0074007 FlyBase:FBrf0089570 FlyBase:FBrf0201176 FlyBase:FBrf0251522 ]
Also Known As "antennales Organ" ; "AntSO" ; "DO" (for all, see Synonyms field below)
