Because the A-delta fiber is thicker than the C fiber, and is thinly sheathed in an electrically insulating material ( myelin ), it carries its signal faster (5–30 m/s ) than the unmyelinated C fiber (0.5–2 m/s). Source: Internet

Function Action potential propagation in myelinated neurons is faster than in unmyelinated neurons because of Saltatory conduction. Source: Internet

There are two types of axons occurring in the peripheral nervous system and the central nervous system: unmyelinated and myelinated axons. Source: Internet

Thus in a myelinated axon, action potentials effectively "jump" from node to node, bypassing the myelinated stretches in between, resulting in a propagation speed much faster than even the fastest unmyelinated axon can sustain. Source: Internet

Initial segment The axon initial segment — the thick, unmyelinated part of an axon that connects directly to the cell body — consists of a specialized complex of proteins. Source: Internet

The sheath enables action potentials to travel faster than in unmyelinated axons of the same diameter, whilst using less energy. Source: Internet
