Figure 7. Comparison of cuticular sensilla and internal receptors.

Figure 7.

(A) Transversal TEM section of P. pacificus cuticular sensilla and internal receptors of the mouth region. One from each sensillum type is labeled in the same false color as the neuron. Note the highly branched dendritic endings of the four URY neurons (blue), which associate with all six inner labial sensilla forming sheet-like branches around the processes of the ILsh and ILso cells. (B–C) Schematic illustrations of the cuticular sensilla in P. pacificus and C. elegans. Inner Labial 1 and 2 (IL), Inner Labial sheath (ILsh), Outer Labial (OL), Cephalic (CEP), URA (A), URY (Y), URX (X), BAG (B), FLP (F), amphid (am).
