Saltatory conduction is the propagation of action potentials (nerve signals) along axons that occurs by jumping from one node of Ranvier (gap between myelinated sections of axon) to the next. (Saltare means "to hop" or "to jump")
By jumping from one node to the next, this increases the conduction velocity, allowing the signal to travel faster.
There are a couple of things that happen during saltatory conduction. The main thing is action potentials being propagated from one node of Ranvier to the next node along the myelinated axons.
Travels along the surface of a neuron's plasma membrane. If the traveling impluse encounters a section of membrane covered with insulating myelin, it simply "jumps" around the myelin..
The myelin sheath
Yes.
the myelin sheath
Saltatory conduction is made possible by myelinated nerve fibers. This is the means through which one node of Ranvier will communicate with the next.
Saltatory Conduction
It is called saltatory conduction. This describes the "jumping" of an action potential from node to node on a myelinated axon.
Saltatory conduction is made possible by gaps in the myelin sheath (called nodes of Ranvier) along the axon, which allow for the action potential to "jump" from one node to the other, increasing conduction velocity.
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.
saltatory propagation
saltatory conduction Saltatory conduction is derived from the Latin word saltare, which means leaping
Saltory conduction only occurs in the myelinated axons.
A myelinated axon
It is the "skipping" pattern that impulses follow to travel down nerve axons.
