That is not the fatty 'material'. They are Glial cells derived from the mesoderm. The nerve cells are derived from ectoderm. The neural cells do not divide and so cancer do not arise from them. The malignancy in brain usually arise from these glial cells.

What is The name of the Microscopic nerve fibers in the myocardium?
the microscopic nerve fibers are called chemocytes
Why is the myelin sheath so important to the nervous system?
Myelin is a fatty substance that insulates and protects nerve cells and allows them to transmit electrical signals quickly.
What organ includes sensory receptors protects other tissues and insulates the body against temperature changes?
The skin includes sensory receptors, protects other tissues, and insulates the body against temperature changes.
A bundle of nerve fibers?
The bundle of the nerve fibers is a collection of the threadlike extension of the nerve cell that consists of the myelin sheath and axon in the nervous system. There are nerve fibers in the peripheral nervous system and the central nervous system.
