Fig. 5From: Eudiplozoon nipponicum: morphofunctional adaptations of diplozoid monogeneans for confronting their hostForebody tegument organisation in Eudiplozoon nipponicum. A. General view of tegument organisation. TEM. B. General view of freeze-fractured tegument. The white double-sided arrows demark the thickness of individual layers comprising the syncytium, musculature and part of the parenchyma. FE, TEM. C. A detail of the fractured apical plasma membrane and subjacent membrane. FE, TEM. D. Fractured tegument, showing the basal lamina separating the syncytium from the body wall musculature. FE, TEM. apm – apical plasma membrane, bl – basal lamina, black arrows – dense protein layer, cm – circular muscle fibres, efapm – exoplasmic fracture face of the apical plasma membrane, er – projections of endoplasmic reticulum, lm – longitudinal muscle fibres, n – nucleus, p – parenchyma, pfsm – protoplasmic fracture face of the subjacent membrane, pm – perpendicular muscle fibres, sc – syncytiumBack to article page
