Notes

The orientation of the cilia pseudotrochus is controlled by muscles inserted on their rootlets. The peculiar structures of buccal and pharyngeal cilia are described: their beating leads the food towards the mastax. The circular and longitudinal muscles of the buccal funnel allow peristaltic movements and probably the rejection of food items not accepted by the mastax receptors.
