The muscle system of the protoscolex. A. Phalloidin staining of a transverse section of the scolex. B. Phalloidin staining of a transverse section of the posterior body. C. Diagram showing the main groups of muscle fibers in the scolex (left, frontal view; right, dorsal view). See the main text for details. Abbreviations: dmf, deep muscle fibers connecting dorso-ventrally adjacent suckers; ilmf, inner longitudinal muscle fibers; S, sucker; slmf, subtegumental longitudinal muscle fibers, scmf, subtegumental circular muscle fibers; stm, subtegumental muscles (referring to both longitudinal and circular muscle fibers); R, rostellum, rm, radial muscles below the rostellar pad; rmfs, radial muscle fibers connecting each sucker to the others and to the rostellum. Asterisks mark several groups of muscle fibers connecting the suckers to each other. Bars represent 50 μm.
