“…The medial elongations and crossing over of the fibres observed in D. kastjani are already known from other polychaetes (Müller, 1999) as well as from other invertebrates (e.g. Platyhelminthes: Rieger et al, 1994;Gnathostomulida: Müller and Sterrer, 2004). This arrangement enables not only contraction but also rotational movements of the prostomium.…”

“…Kreshchenko et al (1999) also observed these muscles in Girardia (D) tigrina with TRITC-conjugated phalloidin and referred to them as 'anchoring muscles'. In Macrostomum hystricinum marinum, which has a simple structured pharynx in the boundary between the body wall and the intestine, Rieger et al (1994) found transverse muscles connecting the body wall and the pharynx. Muscles such as the 'pharynx-anchoring muscles' in Dugesia may be seen widely in turbellarians.…”

“…The terminus of the intestinal duct at the mouth is expected to have longitudinal and circular muscles if it originates from invagination of the body wall. In most turbellarians without a well-developed pharynx, some circular body-wall-muscle fibers turn into the mouth and contribute to the longitudinal musculature of the duct (Rieger et al, 1994;Hooge and Tyler, 1999). In this study, we showed molecular evidence for a relationship between the circular body-wall muscles and the pharyngeal muscles, that is, both muscles contain only MHC-A.…”

Abstract. Female genitalia of lygaeid bugs are characterized by a tube-shaped ductus receptaculi (spermathecal duct) connecting the bursa copulatrix with the highly coiled receptaculum seminis (spermatheca). In this study the morphology and functional anatomy of these structures in Lygaeus simulans were examined by light-, fluorescence-and electron microscopy. In addition, copulating ani mals were freeze fixed and their interconnected genital structures observed using light microscopy. The ductus receptaculi is sepa rated from the receptaculum seminis by a complicated valve. The valve is nearly surrounded by the spermathecal muscle, which controls its opening. The ductus receptaculi leads into the proximal convoluted tube of the receptaculum seminis. Both the ductus receptaculi and the convoluted tube are composed of a single layer of epithelial cells lined by a thick electron dense apical cuticle. The distal part of the receptaculum seminis is a brownish, irregularly coiled, blind ending canal made of small epithelial cells cov ered with cuticle. Big glands are present in the epidermal layer. The cuticle of this distal part is much thinner and features concentric lamellae. The lumen of the receptaculum seminis cannot be expanded. For transfering sperm into the receptaculum the male aedeagus is equipped with a long, tube-like, sclerotized appendix (processus gonopori), which enlarges the ductus receptaculi con siderably during copulation. For successful insemination the tip of the processus gonopori has to pass the valve. The convoluted tube, the valve and the surrounding spermathecal muscle may enable females to control insemination and egg fertilization.
