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.

BlakeThere 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..

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 type of nervous system conduction occurs in myelinated axons?
Saltatory Conduction
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 the presence of myelin sheaths that cover the axons of neurons. These myelin sheaths act as insulators, allowing for the rapid transmission of nerve impulses by jumping from one node of Ranvier to the next, speeding up the conduction of electrical signals along the neuron.
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.
Why is saltatory conduction relatively rapid compared to continuous conduction?
Saltatory conduction is faster than continuous conduction because in saltatory conduction, the electrical signal jumps between nodes of Ranvier on the myelinated axon, skipping the sections covered by myelin. This allows the signal to travel faster as it doesn't have to travel the entire length of the axon.
How is saltatory conduction different from continuous conduction?
Saltatory conduction occurs in myelinated neurons where the action potential jumps from one node of Ranvier to the next, speeding up the transmission of signals. In comparison, continuous conduction occurs in unmyelinated neurons where the action potential moves along the entire length of the axon, which is slower than saltatory conduction.
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 most related to saltatory conduction dendrites or choroid plexus or nodes or ranvier or astrocytes?
Nodes of Ranvier are most related to saltatory conduction. These are gaps in the myelin sheath along the axon where action potentials are regenerated, allowing for faster conduction of electrical impulses. Saltatory conduction is the rapid jumping of action potentials between these nodes in myelinated neurons.
Does saltatory conduction only occur in CNS?
Saltory conduction only occurs in the myelinated axons.
Saltatory conduction is made possible by?
Saltatory conduction is made possible by the presence of myelin sheaths around axons. These insulating sheaths allow for the rapid propagation of action potentials by forcing the electrical signal to "jump" between nodes of Ranvier. This results in faster and more efficient transmission of nerve impulses along the axon.
What type of axon allows saltatory conduction?
Myelinated axons allow for saltatory conduction, which is a faster method of transmitting action potentials. The myelin sheath insulates the axon and allows the action potential to "jump" from one node of Ranvier to the next, speeding up the process. Unmyelinated axons do not support saltatory conduction.
