This scanning electron micrograph (SEM) clearly showed the ventral surface of a Giardia muris
trophozoite. The ventral adhesive disk resembles a suction cup, where overlapping microtubules in the cytoplasm form a number-6-shaped figure. Giardia muris
has four pairs of flagella that are responsible for the organisms motility. The adhesive disk facilitates adherence of the protozoan to the intestinal surface.
