The axoneme is the internal, motile skeleton of a flagellum. It is composed of a highly conserved '9+2' arrangement of microtubules: nine pairs of microtubules (doublets) arranged in a circle around a central pair of single microtubules. This complex structure, powered by dynein motor proteins sliding the microtubules past each other, is what generates the whip-like beating motion of the flagellum. This fundamental eukaryotic structure is essential for the locomotion of flagellated parasites like Giardia and Trichomonas, allowing them to swim through luminal fluids to reach and colonize their host habitats.
