What else can I help you with?
What does the sheath do in the nerve cell?
The myelin sheath acts as a covering on the axon of a neuron just as the covering on the cord you plug into an electrical socket. If it is damaged, the current can be "short circuited" and the neuron and the axon will not function. This sheath allows impulses to travel rapidly. MS is a disease where these sheaths are damaged.
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.
What is the name for the insulation covering many neurons?
Myelin sheath. This is the insulating sheath which covers most of the axon, between the Axon Hillock and Collateral branches of the 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.
Where are the nodes of a neuron located?
Between myelin segments surrounding the axon The axon of a neuron is the single long fibre which caries impulses away from the cell body. It is surrounded by a fatty layer, the myelin sheath, produced by Schwann cells arranged along the length of the axon. The gaps between the myelin sheath cells are called nodes of Ranvier. See http://en.wikipedia.org/wiki/Axon for more information and a diagram. easy answer between the myelin segments surrounding the axon b. between myelin segments surrounding the axon
What is the many layered covering surrounding the neuron?
Myelin
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 insulating material found around a neuron?
myelin, although it is really only around the AXON of the neuron, not the whole neuron.
What cell produces the myelin in peripheral nerves?
Schwann cells produce myelin in peripheral nerves. Schwann cells wrap around the axon of a neuron to form the myelin sheath, which helps to insulate and speed up the conduction of nerve impulses.
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 is the covering of a fatty material that speeds up the passage of a nerve impulse?
The covering of a fatty material that speeds up the passage of a nerve impulse is called the myelin sheath. It is made of lipids and proteins and acts as an insulating layer around the axon of a neuron, allowing for faster transmission of electrical signals.
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.
