Exempel på sucker

• The procercoid possesses a well-developed anterior part (scolex) with four muscular suckers.

• Certainly any decrease in size of the ventral sucker is minor.

• The cirrus pouch is small and stout, lying immediately and entirely in front of the ventral sucker.

• Muscle fibres from the somatic muscle layers and the ventral sucker have been isolated and images obtained with phase-contrast microscopy and scanning electron microscopy.

• Isolated muscle fibres from the ventral sucker may represent a more homogeneous population of muscle fibres than fibres isolated from a whole fluke digest.

• The physical size of the sucker results in a broadening of the worm at this point and is generally the widest aspect of the worm.

• Hypothetically, glandular secretions are involved in tissue degradation (disintegration of the papilla and attached sucker following pairing) and fusion of the adjacent tegument.

• It is probably not a result of atrophy of the sucker; the suckers of immatures and adults show no signs of degradation.

• Partially digested ventral suckers of adult flukes were prepared as described previously, then fixed and processed for phalloidin staining.

• The eggs were scattered around the ovary and along the left side of the ventral sucker.

• These are seen on the oral and ventral suckers and lateral, ventral and dorsal body surfaces.

• The oral sucker is subterminal and measures about 0"16 mm. in diameter.

• The excretory vesicle is placed at the posterior end slightly in front, and at the side of, the large sucker.

• Once both ventral suckers are attached to their respective papillae, lysis and fusion of the adjoining tissues begin.

• On the scolex, there were four suckers and two rows of hooklets.
