The gaps in the myelin sheath, known as Nodes of Ranvier, are necessary for the proper conduction of nerve impulses. They allow for a faster transmission of electrical signals along the axon by allowing the action potential to "jump" from one node to the next, a process called saltatory conduction. This increases the speed and efficiency of nerve impulse transmission.

What is myelin sheath on nerve fibers?
The endoneurium surrounds and protects the 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
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 the sheath of the Schwann Cell also called?
Surrounding the myelin sheath, there is a thin membrane called neurilemmal sheath. This is also called neurilemma or sheath of Schwann. This contains Schwann cells, which have flattened and elongated nuclei. The cytoplasm is thin and modified to form the thin sheath of neurilemma enclosing the myelin sheath. One nucleus is present in each internode of the axon. The nucleus is situated between myelin sheath adn neurilemma. At the node of Ranvier (where myelin sheath is absent), the neurilemma invaginates and runs up to axolemma in the form of a finger like process. In nonmyelinated nerve fiber, the neurilemma continuously surrounds axolemma. Neurilemma is absent in central nervous system. Neurilemma is necessary for the formation of myelin sheath (myelinogeneis).
Where are nodes of ranvier found?
In the fatty myelin sheath there are gaps between the axons. The myelin sheath gaps are referred to as the nodes of Ranvier.
Gaps in myelin sheath?
Gaps in the myelin sheath can result in reduced conduction velocity of nerve impulses, leading to impaired communication between neurons. This can manifest as symptoms such as weakness, numbness, and coordination issues. Conditions like multiple sclerosis can cause damage to the myelin sheath, resulting in these gaps.
What are the gaps between the myelin sheath along an axon?
Node of Ranvier
What are the gaps found along along a myelin sheath?
The gaps found along a myelin sheath are called nodes of Ranvier. These gaps allow for the rapid conduction of nerve impulses by allowing the action potential to jump from one node to the next, a process known as saltatory conduction.

What is the myelin sheath's function?
The function of the myelin sheath is to insulate the axon of the neuron. When there are gaps in the sheath, known as nodes of Ranvier, the nerve impulse can jump from gap to gap, thus increasing greatly the speed of conduction of the nerve impulse. This is known as saltatory conduction.

What is the insulating layer wrapped around nerve cells that increases the speed of nerve impulse transmission?
The insulating layer wrapped around nerve cells is called the myelin sheath. It helps to increase the speed of nerve impulse transmission by reducing the loss of electrical signals that normally occurs as they travel along the nerve cells.
What does myelin sheath wrap around?
The myelin sheath wraps around the axons of neurons in the nervous system. This fatty layer helps to insulate and protect the axon, allowing for faster transmission of electrical signals along the neuron.
