These outer-tegumental membranes form many surface pits that substantially increase the surface area of the schistosome. The underlying syncytial-matrix contains some mitochondria, many vesicular structures and an extensive cytoskeleton. A basal lamina separates the syncytium from a layer of muscle cells. Nuclei and ribosomes are located in cytons, which are located underneath the muscle layer and connected by microtubule-lined cytoplasmic connections. ",
