При световой и растровой электронной микроскопии ротовой присоски F. hepatica установлено, что она состоит из кольцевых и продольных мышечных образований разной сложности, которые отличаются степенью развития мышечных волокон. Поперечные мышечные волокна связывают кольцевые мышцы. Ротовая присоска выполняет функцию питания и прикрепления. Она очень мобильна и ее диаметр изменчив за счет сокращения или расслабления мышц. При сокращении мышечных волокон полость присоски уменьшается за счет создавшегося вакуума в полости присоски F. hepatica прочно закрепляется на стенке желчных протоков печени. На дне ротовой присоски расположено ротовое отверстие. При голодании F. hepatica кольцевые мышцы сокращаются, закрывают ротовое отверстие и ротовая присоска принимает вид воронки. </p></abstract><trans-abstract xml:lang="en"><p>The structure of oral sucker of trematode Fаsciolа hepatica, an organ of fixation to the walls of hepatic ducts in human and vertebrate animals, has been studied. Light and stereoscanelectronmicroscopicobservations on the oral sucker of trematode F. hepatica allow to determine that it consists of various complex circular and longitudinal muscle layers that differ from each other in the stageof development of musclefibers. Transverse muscle fibers connect circular muscles. The oral sucker performs nutrition and attachment functions. The oral sucker is very mobile and its diameter changes due to muscle contraction and relaxation. At contraction of musclefibers the cavity of oral sucker becomes smaller because of the vacuum generated in its cavity. F. hepatica is firmly attached to the walls of hepatic ducts. On the bottom of oral sucker is a mouth opening. When F. hepatica  feels hungry its circular muscles contract, cover the mouth opening, and the oral sucker takes the shape of a funnel. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>Fаsciola hepatica</kwd><kwd>ротовая присоска</kwd><kwd>морфология</kwd><kwd>электронная микроскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Fаsciola hepatica</kwd><kwd>oral sucker</kwd><kwd>morphology</kwd><kwd>scanning electron microscopy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Соколина Ф.
