TY - JOUR AU1 - GRIMSTONE, A. V. AB - CILIA AND FLAGELLA A. V. Grimstone 1. Structure of Cilia and Flagella The essential uniformity of flagellar structure was demon- strated before the advent of methods of thin sectioning by Manton's careful reconstructions from fragmented material (see, for example, Manton & Clarke, 1952). There are apparently no exceptions to the rule that all vibratile cilia and flagpiia contain eleven longitudinal fibres, nine of which form a cylinder around a central pair. The outer fibres are duplex A. V. GRIMSTONE M.A. PhJD. structures, each composed of two subfibres, while the central Department of Zoology pair are single. All the fibres appear hollow in cross-section University of Cambridge (Plate 27: B, C, F). Both central fibres and outer subfibres are about 240 k in diameter and all apparently run straight along the length of the cilium or flagellum. Structure of cilia and flagella Basal bodies These fibres, immersed in a homogeneous matrix and sur- Sperm tails rounded by a membrane continuous with that of the rest of Modified cilia and flagella the cytoplasm, were until recently regarded as the sole struc- Development and function tural components of the ordinary cilium or flagellum.
