摘要: The covering layer of Gyrocotyle, which is thought to occupy an intermediate position between the monogeneans and cestodes, resembles that cestodes more than epidermis ectoparasitic monogeneans. It a cytoplasmic bearing densely arranged microvilli connected parenchymally situated cell bodies. Gyrocotyle differ from microtriches tapeworms in lacking thickened tip. Vesicles at free edge are associated with disintegrating striated rod-bodies therefore probably secretory rather concerned micropinocytosis. epidermal bodies have characteristics cells appear elaborate occur throughout outer may consist condensed mucoprotein. Cells electron opaque cytoplasm neighbourhood been identified as myoblasts. posterior rosette appears be specialized for adhesion gland secreting PAS positive material line ventral surface this region bears short bifurcate microvilli.
