Fig. 18: Infraciliature - drawing of pellicle and cortex of Tetrahymena

Segments of two kineties or rows of basal body (bb)/cilium (c) complexes. Kinetodesmal fibers (kd) arise from the left side of the proximal end of each basal body and angle up to the cell’s pellicle. Transverse microtubules (tr mt) extend to the right and postciliary microtubules (po mt) angle posteriorly and to the left of the kinety. One or two basal microtubules (b mt) extend along the right of the kinety at the proximal end of the basal bodies. A band of longitudinal microtubules (lo mt) lies between the epiplasm (ep) and the alveoli (al) to the left of the kinety. Mucocysts (mu) approach the plasma membrane (pm) through the septa separating alveoli along the primary (pr mer) and secondary meridians (sec mer). Drawn by H. C. Lyman. Published in J. Protozool. 14:553-565, 1967.
