b. dendrites
c. myelin
d. astrocytes

A. axons  

Explanation:

The axon is a part of the neuron that is responsible for conducting electrical impulses from the cell body to another, more distant location, such as a muscle or another neuron. The axons are coated with sphingolipids.

Each neuron has a single axon, which is born from the implantation cone, still located in the pericary region of the neuron; the axons do not branch off abundantly, and when they do they give rise to the so-called collaterals.
