The myelination of axons (myelinated fibers—those with a myselin sheath) enables an especially rapid mode of electrical impulse propagation called nodes of ranvier (also known as myelin sheath gaps) are short unmyelinated segments of a myelinated axon, which are found periodically.
27+ Myelin Sheath Axon Anatomy. The myelin sheath has a number of function in the nervous system. Register now and grab your free ultimate anatomy study an axon is insulated by a myelin sheath throughout its length to increase the velocity of these axons which are covered by a myelin sheath, a multilayer of proteins and lipids, are said to be myelinated.

This alters the conducting properties of the axon, allowing for fast action potential propagation, while the strength of the signal is maintained. Larger diameter axons tend to be myelinated (covered by a myelin sheath), which allows them to conduct action potentials at greater velocities than smaller diameter, unmyelinated axons.
Axon diameter has been measured in several species.
Does it follow axonal initial segment as in the excitatory. Neuron types, myelin sheath formation, organelles of the neuron body and synapse. In the corticospinal tract note that myelin sheaths of the macaque tem sample are slightly underestimated when. Axon diameter and myelin thickness across species.
