Location: Head
Description: Exposed to the internal environment of the animal. Cell bodies are situated anterior to the nerve ring. Processes travel in subdorsal and subventral labial process bundles. URY dendrites terminate in variable membranous nonciliated, branched processes and they may extend across the midline boundary into the adjacent quadrant possibly to interact with other sensilla (Doroquez et al., 2014). URY endings are apposed to ILshD and OLQshD processes.
Neurotransmitter/ Neuropeptide:
- Glutamate
(Saiz et al., 2013)

Innexin expression:
- INX-1a
- INX-1b
- INX-2
- INX-7
- INX-10a
- INX-11
- INX-14
- UNC-7 only in dauer
- UNC-9
(Bhattacharya et al., 2019; Altun et al., 2009)
Receptor expression:
- PDFR-1; pigment dispersing factor receptor ortholog
- SER-1; (inconsistently) serotonin receptor
(Barrios et al., 2012; Dernovici et al., 2007; Carnell et al., 2005)
Function:
- Part of the neuronal circuit that functions in mate-searching behavior of males (Barrios et al., 2012)
- May function in pathogen sensing (Pradel et al., 2007)

URYDL (AB alapapapp) development in the embryo. Dorsal view. Bottom is left side of the embryo. Spheres indicate individual nuclei. Black sphere: ancestors of URYDL; dark grey spheres: apoptotic cells; other cells follow the WA color code (after they acquire specific cell or tissue identities). 0 min is fertilization.
