Based on diameter and conduction speed, nerve fibres are classified into 3 types:
- Type A Fibres: These are the largest and fastest conducting fibres, divided into Aα, Aβ, Aγ, and Aδ fibres. They include motor neurons and sensory fibers such as those for touch.
- Type B Fibres: These are myelinated fibres with an intermediate diameter and conduction speed. ...
- Type C Fibres: These are the smallest and slowest conducting fibers, and they are unmyelinated. ...

Axon - Wikipedia
An axon (from Greek ἄξων áxōn, axis) or nerve fiber (or nerve fibre: see spelling differences) is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body. The function of the axon is to transmit information to different neurons, muscles, and glands. In certain sensory neurons (pseudounipolar neurons), such as those for touch and warmth, the axons are called afferent nerve fibers
