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
It occurs because no nerve impulses can not flow through the axonal membrane where there is fatty myelin insulation
Saltatory conduction occurs when nerve impulses are transmitted along the myelinated nerve. In this type of conduction, depolarization is repeated as impulses jump from node to node.
The nodes of ramvier.
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.
Conduction doesn't occur in fluids. Convection currents are the form in which heat travels in fluids.
It can occur through conduction, convection and radiation.
Because, conduction is the transfer of heat flow fro one object to another. So that means they must touch to make conduction occur.
BLA
Saltory conduction only occurs in the myelinated 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.
Saltatory Conduction
It is called saltatory conduction. This describes the "jumping" of an action potential from node to node on a myelinated axon.
saltatory propagation
the myelin sheath
saltatory conduction Saltatory conduction is derived from the Latin word saltare, which means leaping
Saltatory conduction is made possible by myelinated nerve fibers. This is the means through which one node of Ranvier will communicate with the next.
A myelinated axon
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.
It is the "skipping" pattern that impulses follow to travel down nerve axons.
