Question

Quizplus · Accepted Answer

Microtubules are the largest of the three types of cytoskeleton fibers. They are made up of protein subunits called tubulin and have a diameter of 25 nanometers, whereas microfilaments are made up of actin and have a diameter of 7 nanometers. Neurofilaments and tau proteins are subtypes of intermediate filaments and are smaller than microtubules.
