campaniform sensillum of proximal dorsal radius campaniform sensillum of dorsal radius Sc25 fly_anatomy.ontology d.Rad.B + d.Rad.C FBbt:00004345 sensillum campaniformium of dorsal radius Sc25 VFB:FBbt_00004345 Campaniform sensillum belonging to a more dispersed group of cells, distal to the Sc4d cells, on the dorsal side of the proximal radius of the adult wing. These cells belong to two distinct fields. The first has seven elliptical sensilla with low profile and with a socket (type 6), distributed in a round patch, with each sensillum between 2.5-3.0 micrometers in length (d.Rad.B). The second has around 17 circular sensilla, with low profile and without socket (type 4), with each sensillum between 2.5-3.5 micrometers in diameter (d.Rad.C).
