Summary

Electron microscope has demonstrated new facts in the microscopical anatomy of the bladder wall of Cysticercus bovis. The distal cytoplasm of the tegument is relatively low and dominated by vacuolar structures. The microtriches are very long and their distal portion contains an electron-dense core. The basement layer forms evaginations into the distal cytoplasm. The flame cells have marked cytoplasmic extensions in the longitudinal axis; the arrangement of chromatin in the nucleus is typical of these cells. The morphology of the functional part is similar to that of the flame cells of adult cestodes. A description is given of the appearance of the various types of ductules and ducts. Typical of these are the extensions of the wall, the rod-shaped bodies in the cytoplasm of the larger ducts and the bleblike processes on the inner wall surface. The contractile structures of the parenchyma of the wall differ greatly from the muscle bundles of the subtegumental region both in shape and size.
