Microtubules are cylindrical tubes, 20-25 nm in diameter. They are composed of subunits of the protein tubulin--these subunits are termed alpha and beta. Microtubules act as a scaffold to determine cell shape, and provide a set of tracks for cell organelles and vesicles to move on.his structure acts as both muscle and skeleton, for movement and stability. The long fibers of the cytoskeleton are polymers of subunits. The primary types of fibers comprising the cytoskeleton are microfilaments, microtubules, and intermediate filaments.
When their results were published in professional journals in 1967, they were widely circulated across mass media in abbreviated form. Because the figures were so easy to remember, most people forgot about what they really meant. Hence, the myth that communication is only 7 percent verbal and 93 percent non-verbal was born. And we have been suffering from it ever since.
