Cross sections of striated bands and infraciliary lattice arms. Filaments of the striated bands are less densely packed than the infraciliary lattice. Kinetodesmal fibers and postciliary microtubules are also cross sectioned and are seen to come to lie near each other in the lateral ridges. A linkage would provide additional strength to the kineties. The observer is looking at a cross section of the cell from the posterior toward the anterior of the cell. TEM taken on 6/28/69 by R. Allen with Philips 300 operating at 60kV. Neg. 36,500X.
