1 These fibers are the thickest and fastest conducting. 2  They are myelinated. 3  They have a diameter of 1.5-20 micron. 4  Their speed of conduction is 4-120 m/sec, which shows that they have a really fast conduction of impulse. 5  Examples of type A fibers are skeletomotor fibers, fusimotor fibers and afferent fibers to skin.
