A fibers have the largest diameter among the three types of axons. They are myelinated and transmit signals fastest, making them responsible for conveying sensations of touch and motor control. B fibers are also myelinated, but are smaller in diameter and transmit signals slower than A fibers. C fibers are unmyelinated and have the smallest diameter, transmitting signals slowest among the three types of axons.
