No, internodes are not the gaps in myelin along the axon; they refer to the segments of the axon that are covered by myelin sheaths. The gaps between these myelinated segments are called nodes of Ranvier. These nodes play a crucial role in the conduction of nerve impulses, allowing for faster transmission through a process called saltatory conduction.
What else can I help you with?
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 surrounds a single long axon that leaves many gaps?
The single long axon is surrounded by myelin sheath, which is a fatty substance produced by Schwann cells in the peripheral nervous system. The gaps along the axon are called nodes of Ranvier, where the axon is exposed and allows for faster nerve impulse transmission known as saltatory conduction.
What is the layer of fat cells that helps electrical impluses travel faster along the axon of a neuron?
The layer of fat cells that helps electrical impulses travel faster along the axon of a neuron is called the myelin sheath. Myelin is a fatty substance that insulates the axon, allowing for quicker transmission of electrical signals through a process called saltatory conduction, where impulses jump between the gaps in the myelin known as the nodes of Ranvier. This enhances the speed and efficiency of neuronal communication.
What are gaps in myelin sheath that allow nerve impulses to quickly move down the axon by jumping from section to section?
The gaps in the myelin sheath are called Nodes of Ranvier. These nodes are crucial for a process known as saltatory conduction, where nerve impulses jump from one node to the next, significantly increasing the speed of transmission along the axon. This jumping occurs because the myelin sheath insulates the axon, allowing the electrical signal to travel more efficiently. As a result, the presence of these nodes enhances the overall speed and efficiency of neural communication.
What coats an axon?
An axon is coated with a myelin sheath, which is composed of fatty substances produced by glial cells. This sheath insulates the axon and facilitates the rapid transmission of electrical impulses along the nerve fiber. In the central nervous system, oligodendrocytes form the myelin, while in the peripheral nervous system, Schwann cells are responsible for its formation. The gaps in the myelin sheath, called nodes of Ranvier, allow for efficient signal propagation through a process known as saltatory conduction.
What are the gaps between the myelin sheath along an axon?
Node of Ranvier
Where is the axon not insulated with myelin?
The axon is not insulated with myelin at the nodes of Ranvier. These are small gaps along the axon where the myelin sheath is absent and allow for faster propagation of action potentials by saltatory conduction.

What are the gaps in the myelin sheath that create non-insulated areas along an axon?
nodes (:I do not disagree with that answer, but I just want to point out that the nodes have a special name. They are called Nodes of Ranvier, named after the man that discovered them (so Ranvier is capitalized). C:

What are specialized coverings of the axon?
Specialized coverings of the axon include the myelin sheath, which is formed by oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. The myelin sheath acts as an insulating layer that speeds up the conduction of nerve impulses along the axon. Nodes of Ranvier are gaps in the myelin sheath where action potentials are regenerated, allowing for saltatory conduction.
The material surrounding the axon that increases the speed of the nerve impulse is?
The material surrounding the axon that increases the speed of the nerve impulse is the myelin sheath. It is made of fatty substances and acts as an insulator, allowing for faster conduction of the electrical signal along the axon. Nodes of Ranvier are the gaps in the myelin sheath where the signal jumps between to speed up transmission.

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.
Which structure of a neuron increases the speed of impulse transmission?
The structure of a neuron that increases the speed of impulse transmission is the myelin sheath. This fatty insulating layer surrounds the axon and allows electrical impulses to jump between the nodes of Ranvier, which are gaps in the myelin. This process, known as saltatory conduction, significantly enhances the speed of signal transmission along the axon.
