What does not belong nodes of ranvier myelin sheath cell body axon?
Cell body.
Do Schwann cells compose the cell body?
Myelin Sheath Cytoplasm Dendrites Cell Body
What role does myelin play in the body?
It acts like an electrical insulator.
It insulates the axon of the neuron?
An insulating layer that surrounds the axon is a myelin sheath.
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 kind of a coating do axons have?
Axons are coated in a fatty substance called myelin - a "myelin sheath". It insulates and protects the cell body of neurones. The myelin doesn't completely coat the axon: there are small gaps between the myelin, called the nodes of Ranvier.
What does not belong nodes of ranvier myelin sheath cell body axon?
Cell body.
Do Schwann cells compose the cell body?
Myelin Sheath Cytoplasm Dendrites Cell Body
What role does myelin play in the body?
It acts like an electrical insulator.
What is the cause of MS?
The Myelin Sheath is damaged and allows ions to escape the axon
What insulates nerve fibers?
Myelin sheaths insulate nerve fibers
Gaps in myelin sheath?
You can have benign tumors of myelin sheath cells, like astrocytoma. Nerve cells do not divide and so you do not get tumors of nerve cells. Also destruction of the myelin sheath is the cause of MS (multiple sclerosis).
What are oligodendrocytes responsible for?
myelination of the axons and the dendrites are responsible for connection between the cell body and myelin
What is a group of axons bundled together coated in myelin that travels together through the body?
A Nerve
What applicants are needed for group work to insulate nerve fibers through an entire body?
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.
What effect will multiple sclerosis a degenerative disorder that cause myelin to disintegrate have on a person's nerve impulses?
They will slow down
