First ultrastructural investigation of the pharynx apparatus of Scutigera coleoptrata (Chilopoda: Notostigmophora)
The organisation and possible function of the pharynx apparatus of Scutigera coleoptrata was first described in 1967 by Seifert. The pharynx apparatus in the foregut of S. coleoptrata consists of a ballshaped outgrowth of the dorsal pharyngeal wall, the pistil, and a cooperating ventral groove, the pharynx furrow. Here we present new structural details of the pistil and the pharynx furrow with its underlying epithelium, using LM, TEM, and SEM techniques.
