Muscular system of Paramphistomum cervi (Zeder, 1790) (Trematoda, Рaramphistomatidae)
Descriptions of a musculation of a body, organs of affixion and copulative apparatus of Paramphistomum cervi trematoda, Paramphistomatidae) are resulted. The body-wall has three muscular layers - ring, longitudinal and diagonal. Muscles of a diagonal layer are crossed at an obtuse angle - are synergists of ring muscles. The parenchymal musculation includes longitudinal peripheric and intercecal, dorsoventral, radial muscles, esophagus protractors, retractors of preoral lip. Longitudinal parenchymal muscles fasten the forward ends to an oral sucker, back to ventral sucker that promotes the coordinated work of suckers. The dorsoventral musculation is educed poorly owing to what a body of a worm has round section. The musculation of a sexual cloaca is various. The ring peripheric is educed everywhere, it forms a ventral and sexual sphincter. The oral sucker is rich with various muscles - outside and intrinsic longitudinal, outside and intrinsic ring, semiring, diagonal, radial. Semiring muscles can bend a rimous oral cavity ventrally or dorsad. The musculation of a ventral sucker is presented outside and intrinsic diagonal, outside and intrinsic ring, outside both intrinsic longitudinal, and radial fibres.
