mouth drawing

Description:

This drawing presents the author’s understanding of the ultrastructural organization of the mouth region of Stephanopogon apogon. The opening of the mouth is to the left, and is surrounded by lips. These are strengthened inside by a quoit of fibrous material. Rods of microtubules support the region leading into the body, and there are many small gland-like folds of the membrane leading into this region. The body is supported by flat ribbons of microtubules. There are flagella on the lower surface of the cell and these are held in place by crown-like arrays of microtubules, and are interconnected by flat plates of material.
