Figure 16-41The arrangement of microtubules in a cilium or flagellum

(A) Electron micrograph of the flagellum of a green algal cell ( Chlamydo-monas) shown in cross-section, illustrating the distinctive "9 + 2" arrangement of microtubules. (B) Diagram of the parts. The various projections from the microtubules link them together and occur at regular intervals along the length of the axoneme. (A, courtesy of Lewis Tilney.)
