Myelin is the material that covers the spinal cord. It protects the cord from damage. If the myelin wears away, then a person is said to have Multiple Sclerosis.

Are muscles and glands myelinated?

Muscles and glands are not myelinated. It is the axon of a neuron that is myelinated. The myelin forms a layer called myelin sheath that makes the nervous system function properly.


What is the myelin sheath's function?

The function of the myelin sheath is to insulate the axon of the neuron. When there are gaps in the sheath, known as nodes of Ranvier, the nerve impulse can jump from gap to gap, thus increasing greatly the speed of conduction of the nerve impulse. This is known as saltatory conduction.

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.


How do lipids help nerve function?

Some lipids act as an insulator, similar to the covering on an electrical cord. This is called a myelin sheath.


What is the definition of myelin sheath?

A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.
