Movement of impulse from one node of Ranvier to the next node of Ranvier is termed?

It is called as saltatory conduction. The term has come from the Latin word saltare. That means to hop or to leap. The conduction rate is greatly hastened by this method.

What happens when an impulse reaches the end of an axon?
It reaches the synapse and sends neurotransmitters to start a new impulse to the next neuron
List the cellular structures over which an impulse would pass?
In the body, an electrical impulse travels through the neurons, or nerve cells, to send signals to and from the brain. The Dendrites of the neuron accept the impulse, send it through the soma, down the axon, and to the axon terminal, where it'll be sent to the next neuron, almost instantly.
Which ion causes neurotransmitter vesicles to fuse with the axon's membrane during the conduction of a nerve impulse from one neuron to the next?
calcium
What happens at the synapse between two neuron?
At the synapse, the electrical impulse between the two neutrons at synapse set of chain chemical reactions which create a chemical impulse at the synapse.
When you observe a change in the weather from one day to the next it is due to the movement of what?
air masses
What structures cross the synapse to generate the next impulse?
Neurotransmitters.
When was The Next Movement created?
The Next Movement was created in 1999.
What does the axial do?
Carry a nerve impulse to the next nerve OR to an effector cell.
How does a nerve impulse cross the gap between the axon and the next?
Curently unknown...
______ have receptors for the neurotransmitter by which impulse transmits and forward in the next nerve?
Synaptic of dendrite
What does the axial filament do?
Carry a nerve impulse to the next nerve OR to an effector cell.
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.
How does myelin increase the speed of nerve impulse conduction?
The way an action potential propagates is by opening voltage-gated sodium channels which depolarize the cell. Think about how long it would take to conduct an action potential if you had to open channels along the entire length of the axon and wait for sodium influx. In the case of the myelinated nerve fibers, the myelin sheath covers large portions of the axon, leaving uncovered spaces known as nodes of Ranvier. The sodium channels in a myleinated nerve fiber are only at the nodes of Ranvier. So one sodium channel opening depolarizes a much greater length of the axon until it reaches the next node of Ranvier, where the voltage-gated sodium channels open and this cycle continues. In essence the AP "hops" around, covering much greater distance in a shorter amount of time.
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.
What happens when an impulse reaches the end of an axon?
It reaches the synapse and sends neurotransmitters to start a new impulse to the next neuron
What is generation is the offspring of the P or parental generation?
The offspring of the Parental generation are termed the F1 or First filial generation.
State why there is a brief delay in the transmission of an impulse across the synapse?
The impulse must go from one neuron to the next. To do this, it must change from an electrical to a chemical signal, and back to an electrical signal when it reaches the next neuron. Electrical signals are impossibly fast, but neurotransmitters cannot cross a synapse that fast. So, the impulse is at its slowest point when it crosses the synapse.
