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.
What else can I help you with?
Impulses are conducted rapidly if is present?
Myelin sheath. It is a fatty layer that surrounds the axon of a neuron and helps to speed up the transmission of electrical impulses along the neuron.
When the nerve impulse encounters a myelin-covered section of neuron?
When the nerve impulse encounters a myelin-covered section of a neuron, it jumps between the nodes of Ranvier, allowing for faster transmission speed due to saltatory conduction. Myelin acts as an insulator, preventing the impulse from dissipating and increasing the efficiency of signal transmission along the 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).
The Schwann cell forms a myelin sheath around the?
axons of neurons in the peripheral nervous system. The myelin sheath helps to insulate the axon and improve the speed of electrical signal conduction along the neuron. Schwann cells are also involved in nerve regeneration and support neuron function within the peripheral nervous system.
It insulates the axon of the neuron?
The myelin sheath insulates the axon of a neuron, allowing for faster transmission of electrical signals. This fatty layer helps to speed up the signal conduction by allowing the electrical impulse to jump from one node of Ranvier to the next, a process known as saltatory conduction.
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.
Impulses are conducted rapidly if is present?
Myelin sheath. It is a fatty layer that surrounds the axon of a neuron and helps to speed up the transmission of electrical impulses along the neuron.
When the nerve impulse encounters a myelin-covered section of neuron?
When the nerve impulse encounters a myelin-covered section of a neuron, it jumps between the nodes of Ranvier, allowing for faster transmission speed due to saltatory conduction. Myelin acts as an insulator, preventing the impulse from dissipating and increasing the efficiency of signal transmission along the neuron.
What effect will the destruction of myelin have on the signalling capability of a neuron?
I think that with the destruction of myelin (produced by Oligodendrites in the CNS or the Schwann cells in the PNS that are glial cells that speed up the signal), the signal will be slower or even lost.
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.
What is the fatty substance that speeds up transmission of impulses and surrounds the axon of a neuron?
The fatty substance that surrounds the axon of a neuron and speeds up the transmission of impulses is called myelin. Myelin acts as an insulating layer that helps to maintain the electrical signal within the neuron, allowing for faster and more efficient communication between cells.
What part of a neuron is often encased by a fatty myelin sheath?
It is located on the axon
