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.
Which state of matter does conduction work the best?
Conduction works best with a solid.
When does saltatory conduction occur?
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
Why cant energy travel by conduction through empty space?
Conduction requires the presence of matter. The way conduction works, one atom or molecule bumps into another one, transferring heat energy.
Does conduction work best in gas?
No, conduction works via contact between molecules - as gas molecules are more spaced out from one another, they are less likely to come into contact than molecules in liquids or solids
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.
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 is rapid conduction from node to node?
saltatory propagation
Saltatory conduction is made possible by?
the myelin sheath
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 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
Does saltatory conduction only occur in CNS?
Saltory conduction only occurs in the myelinated axons.
What type of axon allows saltatory conduction?
A myelinated axon
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.....
When current leaps across an insulating myelin sheath from node to node the type of impulse conduction is called what?
Saltatory Conduction
