IntroTABLE 1: Structure of the sensilla.
1The two amphids open to outside through little pockets on the cuticle.
2Nubbins are located at the distal regions of the cilia.
3The six IL1 and six IL2 endings share the same inner labial sensilla, but IL2 dendrites protrude to the outside whereas IL1 endings do not.
4In males, the four CEM neurons open to outside through cephalic sensilla (Ward et al., 1975).
