Saltatory Conduction is a means by which action potentials are transmitted along myelinated nerve fibers. The cytoplasm of an axon is electrically conduction and because myelin inhibits charge leakage through the membrane, depolarization at one node of Ranvier is sufficient to elevate the voltage at a neighboring node to the threshold for action potential initiation. Therefore in myelinated axons, instead of axon propagating as waves but they occur at successive nodes and 'hop' along the axon. This means of travel is much faster than they would otherwise (120 m/sec compared to 35m/sec in unmyelinated nerve fibers). Another advantage of this is that energy is saved as sodium potassium pumps are only required at specific points along the axon. Sean Sinclair

What is salutatory conduction?
Saltatory conduction refers to the propagation of action potentials along myelinated axons from one node of Ranvier to the next node. It increases the conduction velocity of action potentials.
How does conduction occur in a hot water system?
Conduction doesn't occur in fluids. Convection currents are the form in which heat travels in fluids.
How does heat loss occur?
It can occur through conduction, convection and radiation.
Why must substances be touching in order for conduction occur?
Because, conduction is the transfer of heat flow fro one object to another. So that means they must touch to make conduction occur.
Where do convection and conduction occur in the atmosphere?
BLA
Does saltatory conduction only occur in CNS?
Saltory conduction only occurs in the myelinated axons.
Does saltatory conduction occur on unmyelinated axons?
No. I advise you to look up what saltatory conduction is so you will understand why not rather than coming here to get the answers to your homework.
What type of nervous system conduction occurs in myelinated axons?
Saltatory Conduction
Conduction along a myelinated axon is called?
It is called saltatory conduction. This describes the "jumping" of an action potential from node to node on a myelinated axon.
What is rapid conduction from node to node?
saltatory propagation
Saltatory conduction is made possible by?
the myelin sheath
What is the node-to-node jumping regeneration of an action potential along a myelinated axon called?
saltatory conduction Saltatory conduction is derived from the Latin word saltare, which means leaping
What is Saltatory conduction made possible by?
Saltatory conduction is made possible by myelinated nerve fibers. This is the means through which one node of Ranvier will communicate with the next.
What type of axon allows saltatory conduction?
A myelinated axon
Multiple sclerosis impairs which type of impulse propagation?
Saltatory conduction uses myelinated sheaths around the axon to aide in the efficiency that an action potential passes down the nerve's axon by jumping between nodes of ranvier. The word saltatory is taken from the french word "saltare" meaning leap. Saltatory conduction saves time and improves energy efficiency in the nervous system. In some neurological disorders such as Multiple Sclerosis, demyelination of axons occur, resulting in a block of conduction of the action potential.
Saltatory conduction refers to the conduction of impulses in?
It is the "skipping" pattern that impulses follow to travel down nerve axons.
Area where action potentials are generated during saltatory conduction?
Nodes of Ranvier.....
