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.
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.
Area where action potentials are generated during saltatory conduction?
Nodes of Ranvier.....
What happens during continuous conduction?
In Saltatory conduction, the signal leaps or hops from node of Ranvier to another. It uses less energy and it faster. In continuous conduction, the nerve is bare of myelin, moves in continuous waves and the signal is slower.
What is the relationship between myelin and the propagation speed of action potentials?
Electrical signals travel faster in axons that are insulated with myelin. Myelin, produced by glial support cells, wraps around axons and helps electrical current flow down the axon (just like wrapping tape around a leaky water hose would help water flow down the hose).Myelin insulation does not cover the entire axon. Rather there are breaks in the wrapping. These breaks are called nodes of Ranvier. The distance between these nodes is between 0.2 and 2 mm.Action potentials traveling down the axon "jump" from node to node. This is called saltatory conduction which means "to leap." Saltatory conduction is a faster way to travel down an axon than traveling in an axon without myelin.
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.
Is saltatory conduction made possible by large nerves fibers diphasic impulses myelin sheath or erratic transmission of nerve impulses?
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.
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
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
