DNeuroFIG 6: Enlargement of dauer anterior deirid sensillar endings.

A. Cartoon depiction of nondauer anterior deirids, transverse view. The ADE sensillar is filled with TAM, an electron-dense material, and is situated in close proximity to the cuticle. The sheath and socket cells which enclose the ADE cell body are shown.
B. In dauers, the ADE sensillar ending is lengthened and affixed to the cuticle by a unique truss-like structure. The region of contact between the ADE ending and the cuticle is more extensive in dauers than in non-dauers. ADE’s mechanosensory role suggests that these adaptations may improve touch sensitivity in the dauer.
