Flagella cross section
http://www.biology.arizona.edu/cell_bio/tutorials/cytoskeleton/page2.html WebAn explanation is advanced for the remarkable constancy of the pattern of 1 + 9 pairs of fibres found in flagella and cilia. The central pair is produced by the property of the centriole to divide when it attains a certain mass. The peripheral pairs, similarly produced, form in the part proximal to the centriole an ellipse with 9 unequal sectors.
