The axon, both in the vertebrates and invertebrates are often covered with a sheath called the myelin sheath such fibers are called myelinated fiber while those which are not covered are called non-myelinated fiber. Dendrites are always non-myelinated. The myelin surrounding the neurons protects the axon and aids in the speed of transmission.

25 Jun 2008 The nerve diagram should include the cell body, nucleus, dendrites, axon, axon terminals, Schwann cells, and myelin sheath. Tell students that Neurons contain a dendrite, a soma, and an axon. Some axons are covered with a fatty substance known as the myelin sheath, which surrounds the axon, acting Often axons are wrapped by myelin sheaths, leaving exposed sections (node of Ranvier) between Bipolar cells have two processes, the axon and a dendrite.
