Saltatory conduction refers to the process by which action potentials jump between the nodes of Ranvier along myelinated axons. This occurs because the myelin sheath, produced by oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system, insulates the axon, allowing electrical impulses to travel faster. As the action potential reaches a node, it triggers depolarization, which then rapidly propagates to the next node, enhancing the speed and efficiency of signal transmission in neurons.

Why is action potential self regenerating?
By self regenerating, they mean that when you start an action potential, it continues in proximal (nearby) tissue (e.g., nerve). The depolarization of the action potential continues along the nerve.
What does psychologist mean when they say that the action potential follows an all or none law?
When psychologists say that the action potential follows an all-or-none law, they mean that once a neuron's membrane reaches a certain threshold of depolarization, it will fire an action potential at full strength. This means that the action potential either occurs completely or not at all; there is no partial firing. The intensity of the stimulus affects the frequency of action potentials but not their strength. Essentially, it underscores the binary nature of neural signaling.
What will stop conduction once an scr breaks into conduction?
What does "the following"mean ?
What does propogation of an action potential mean?
Propagation of an action potential refers to the transmission of the electrical signal along the length of a neuron's axon. This is achieved through a series of depolarization and repolarization events that allow the action potential to travel in a rapid and coordinated manner from the cell body to the axon terminals. The propagation process ensures that information is effectively communicated from one part of the neuron to another.
Why don't the terms depolarization and action potential mean the same thing?
Depolarization occurs when a stimulus opens sodium channels which allow more sodium to go into the membrane making it less negative and more positive (toward reaching threshold). An action potential can only occur once the membrane reaches threshold which means it has reached the level needed through depolarization. An action potential is a brief reversal in polarity of the membrane making the inside more positive and the outside more negative, the reverse occurs again once the membrane reaches resting potential.
Why is action potential self regenerating?
By self regenerating, they mean that when you start an action potential, it continues in proximal (nearby) tissue (e.g., nerve). The depolarization of the action potential continues along the nerve.
Why is action potential self-regenerating?
By self regenerating, they mean that when you start an action potential, it continues in proximal (nearby) tissue (e.g., nerve). The depolarization of the action potential continues along the nerve.

What Energy Caused The Action?
You will have to specify what action? If you mean movement, a moving object has kinetic energy and energy could have been transferred from a release of chemical or potential energy.
What does 'as useful as' mean?
as useful as " is conduction or what part of speech it is?
What do you mean by conduction of heat?
the transfer of heat from one end of body to another end of body is called conduction of heat

What does conduction cells mean?
It may mean cells that conduct impulses like nerve cells.
