They are more or less equally spaced. The size of the nodes span from 1–2 µm whereas the internodes can be up to (and occasionally even greater than)1.5 millimeters long, depending on the axon diameter and fiber type.

∙ 8y agoNo. Large axons are surrounded by a myelin sheath produced by many layers of Schwann Cells. Interruptions in the myelin sheath between Schwann cells are called Nodes of Ranvier. Small axons do not have a myelin sheath. However, all axons peripheral nervous system are associated with Schwann cells. None of the axons in the central nervous system have Schwann cells nor the Nodes.

Gaps between segments of oligodendrocytes or between individual schwann cells are called?
The spaces along the axon and between the myelin sheath are known as the nodes of Ranvier. They are responsible for speeding up the signals that are transmitted along the axon of the nerve. While the myelin sheath consists of many layers that protect the axon, the nodes of Ranvier are uncovered, giving them the ability to produce an electrical charge.
What are the tiny gaps between adjacent schwann cells called?
Remember that the Schwann cells are made of myelin sheath which insulate the impulse, but also block the sodium ion/potassium ion channels. Therefore there has to be a point where the action potential 'jumps' to, and these are the gaps between the Schwann cells, they are called the Nodes of Ranvier.
What is the difference between an internode and node of ranvier?
A Node of Ranvier is the space between two myelinated segments on an axon, while an internode is the space between two Nodes of Ranvier (alternativenly, the myelinated segment).
What are the different types of lying?
there are no different types of lying. A lie is in fact what it is. The people that make excuses for their wrong doing, are ones that say... Oh its just a whit lie. etc. When in fact we SHOULD NOT lie at all...Be blessed.
What are the 2 major functions of the lymph nodes?
To return to the circulatory system the fluid that leaked out from the capillaries and that wasn't returned to the veins.To filter out any bacteria/viruses by leaving them in the lymph nodes, where an immune response is mounted and they're killed.

What are the gaps between the myelin sheath along an axon?
Node of Ranvier
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.
When did Nodes of Ranvier - band - end?
Nodes of Ranvier - band - ended in 2007.
When was Nodes of Ranvier - band - created?
Nodes of Ranvier - band - was created in 2000.
What is the naked axon between the schwann cell?
Nodes of Ranvier
What is the difference between an internode and node of ranvier?
A Node of Ranvier is the space between two myelinated segments on an axon, while an internode is the space between two Nodes of Ranvier (alternativenly, the myelinated segment).
The gap between schwarm cells in the peripheral system is called a?
Nodes of Ranvier
True or false Nodes of Ranvier occur between adjacent neurons?
True
Where are action potentials regenerated as they propagate along a myelinated axon?
First at the axon hillock where the neural impulse is initially triggered, and then at the nodes of Ranvier as the impulse continues to travel along the axon.(Note that the impulse travels as electrotonic conduction between the nodes of Ranvier, underneath the glial cells which myelinate the axon.)
Are all the gated calcium channels concentrated at the nodes of ranvier of myelinated axons?
no, most gated mandiable channels are concentrated at the nodes of ranvier of myelinated axons.
