Figures 323 & 324 from Chapter 13 (Cilia and Flagella) of 'The Cell' by Don W. Fawcett M.D. The outer segments of the rods and cones of the vertebrate retina and many photoreceptors of invertebrates b...

High resolution image of a tangential section of basal body pair (dikinetid) showing a connecting fiber linking the BBs as well as attachments to a kinetodesmal fiber, to postciliary microtubules, an...

Cilia arise out of shallow depressions in the cell surface. Accessory microtubules, the transverse microtubules and postciliary microtubules splay out from the sides of the basal bodies of a dikinetid...
