A neuron is analogous to an electric wire. If you look at an electric wire going from a lamp to a wall plug, you do not see the actual wire. Instead, you see the insulation. If you would scrape off the insulation, you would see two wires. If those two wires touched you would hear a loud pop. Then a circuit breaker would throw. The wire would be just as good as it was before you removed the insulation. The wire carried the electricity. The insulation protected the wire and let it do its job. Without the insulation, the bulb would not work.
The Myelin sheath protects the nerve from outside forces. It lets it carry its signal free from outside influence. It is a piece of insulation.

When the nerve impulse encounters a myelin-covered section of neuron?
it jumps over the myelin
It insulates the axon of the neuron?
An insulating layer that surrounds the axon is a myelin sheath.
The Schwann cell forms a myelin sheath around the?
axon of a neuron in the peripheral nervous system.Schwann cells form a myelin sheath around the Axon.
What structure insulates neurons?
Myelin Sheath is the structure that insulates most part of neuron
This structure of the neuron plays a role similar to the rubber coating?
Myelin sheath, comprised of glial cells wrapped around an axon one after another (oligodendrocytes in the CNS, schwann cells in the PNS).
What is a part of a neuron affected by multiple sclerosis?
the myelin sheaths. The disease is classified as demyelinating , which is also known as the degeneration of the myelin structures in the neuron.
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.
What is the many layered covering surrounding the neuron?
Myelin
What is the insulating material found around a neuron?
myelin, although it is really only around the AXON of the neuron, not the whole neuron.
When the nerve impulse encounters a myelin-covered section of neuron?
it jumps over the myelin
What would happen if the neuron did not have a myelin sheath?
if neurons didn't have myelin sheath then the transmission of nerve impulses is slowed or stopped
What are the two types of fibers that project from a neuron's cell body?
The two fibers that a neuron has are the nerve and the myelin fibers
In a neuron the myelin sheath serves to insulate?
This insulation acts to increase the rate of transmission of signals. The Myelin Sheath of a neuron consists of fat-containing cells that insulate the axon from electrical activity.
It insulates the axon of the neuron?
An insulating layer that surrounds the axon is a myelin sheath.
In a typical neuron sheaths of fatty tissue are called?
In a typical neuron, sheaths of fatty tissue are called the Myelin sheath. The myelin sheath surrounds parts of the axon of a nerve cell which speeds up neurotransmitters.
What keeps the neuron in working order and has specialized extensions that arise from it?
Myelin sheath
What part of a neuron is often encased by a fatty myelin sheath?
It is located on the axon
