Figure 16. Non-ciliated endings of URX and URY.
(A and A′) 3D reconstruction of two dorsal URX (purple) and four dorsal and ventral URY (pink) dendritic endings. (Bi–iv) Selected cross-sections from distal (Bi) to proximal (Biv). (Bi) The tip of URX (purple) terminates around the ILD sensillum with branches around the process of ILsoD. (Bii) URY is found apposed to processes of OLQshD and ILshD. (Biii) URX and URY endings are found near the OLQ dendrite and also surrounded by processes of OLQsoD, ILsoD, and ILshD. Note singlet MTs in URY. (Biv) URX and URY are found sub-dorsally with IL1D, OLQshD, ILshD, OLQsoD, and ILsoD processes as well as hypodermal cells as neighbors. Scale bars: 500 nm.
