PAPILLAE-ASCARIS

The  dorsal lip bears two minute double papillae  where as single papillae are called amphid. The amphidas are probably chemoreceptors , while the other sensory papillae are perhaps tangoreceptors. The posterior end of the male bears ventral 50 pairs of per-anal papillae in front of the cloacal aperture and 5 pairs  of postanal  anal papillae . The first two pairs of post-anal papillae are double. These papillae of the male help in copulation.
