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.
The myelin sheath makes the electrical impulses go more quickly.
it jumps over the myelin
An insulating layer that surrounds the axon is a myelin sheath.
axon of a neuron in the peripheral nervous system.Schwann cells form a myelin sheath around the Axon.
Myelin Sheath is the structure that insulates most part of neuron
Myelin sheath, comprised of glial cells wrapped around an axon one after another (oligodendrocytes in the CNS, schwann cells in the PNS).
the myelin sheaths. The disease is classified as demyelinating , which is also known as the degeneration of the myelin structures in the neuron.
A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.
Myelin
myelin, although it is really only around the AXON of the neuron, not the whole neuron.
it jumps over the myelin
if neurons didn't have myelin sheath then the transmission of nerve impulses is slowed or stopped
The two fibers that a neuron has are the nerve and the myelin fibers
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.
An insulating layer that surrounds the axon is a myelin sheath.
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.
