∙ 10y ago
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).

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 is the main difference between manet and vanet?
In manet node Mobility is slow. In Manet no Fixed Infrastructure . In Vanet Node Mobility Very high. In Vanet have Fixed Infrastructure . Ex . BTS
Is saltatory conduction faster than conduction on an unmyelinated fiber?
wherever the Schwann cells wrap around the axon, the sodium and potassium ions cannot cross the membrane; the Schwann cells wrap too tightly around the axonal membrane for there to be any extracellular space underneath them. Therefore, the only place that an action potential can occur is at the node of Ranvier-- the space between the Schwann cells. Because of this, the action potential seems to jump from node to node along the axon. "Jumping" is what the word "saltatory" means.
What is node and antinode?
Node is the point on the vibrating string with zero amplitude and antinode is the point where amplitude is the maximum. The distance between successive node will be half of the wavelength.
What is Cardiopulmonary node?
cardiopulmonary node
What is the different between a node and internode?
THE POINT FROM WHERE THE LEAF ARISES IS KNOWN AS NODE. THE DISTANCE between 2 consequitive nodes is known as internode.. from a node leaf arises but from the internode no leaf arises internode is a part of stem as node is not but is a part of leaf
What are the gaps between the myelin sheath along an axon?
Node of Ranvier
What are nodes and internodes?
The node is the part of the stem of the plant from which leaves, branches, and aerial roots emerge. There are many nodes on a plant stem. The distance between each node is called the inter node.
What is the name for the cleft between the internodes of the myelin sheath?
Node of Ranvier
What is the space between nodes called?
The area between two successive nodes is referred to as an internode. The node is the area where a leaf connects to the stem.
What is inter-node?
An internode is a portion of plant stem between nodes. An internodal segment is a portion of nerve fibre.

What are the gaps found along along a myelin sheath?
node of ranvier

How does myelination effect nerve conduction?
Myelination will speed the nerve conduction velocity considerably. Myelin is found in Schwann cells which encircle a given axon. It acts mainly as an insulator so that depolarization in one cell does not set off depolarizations in adjoining cells. When a neural membrane is depolarized, local currents are set up between positive and negative ions causing membrane conduction. In myelinated fibers, the local currents go from one internode (or node of Ranvier) in between two Schwann cells to the next internode. Thus we have "salutatory conduction" where a neural impulse actually jumps from one internode to the next without being conducted down the entire cell membrane.
Movement of impulse from one node of Ranvier to the next node of Ranvier is termed?
It is called as saltatory conduction. The term has come from the Latin word saltare. That means to hop or to leap. The conduction rate is greatly hastened by this method.
The neurolemma and the myelin of the myelinated axons are interrupted at regular intervals along the axon by?
The gap between each myelinated section of an axon is known the node of ranvier.
