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.

What is demyelinating processes?
Demyelination is the process that erodes the sheath that normally protects nerve cells. This causes a reduction in the nerve impulse conduction. One of the diseases that causes this is multiple sclerosis.
The special mode of impulse travel is called?
Propagation
What is impulse propagation?
It is the traveling of the electrical signal down the length of a neuron.
Which of the following types of nerve fiber possesses the fastest speed of impulse propagation?
Type A
Which of the following does not factor into the rate of impulse propagation?
Whether or not the impulse begins in the CNS influences the time necessary for a nerve impulse to be transmitted.
How exitatory and inhibitory interact in normal nerve function?
propagation of impulse pre synaptic to post synaptic
The primary function of the myocardial working cell include a automaticit b regeneration contraction and relaxation impulse propagation?
CONTRACTION
A factor that determines the rate of impulse propagation or conduction velocity along an axon?
The speed at which neural impulses are transmitted. Diameter of the axon Degree of myelination of the axon
How does movement of electrical impulse relate to the contraction of the chambers of the heart?
The impulse shocks the left and right atria of the heart. This pumps blood into the left and right ventricle. The ventricles then receive the impulse and pump the blood. The movement of the electrical impulse allows the blood to move through multiple areas of the heart with only one impulse.
Does nerve conduction use ATP?
True- it is a multifunctional nucleoside triphosphate that is used in cells as a coenzyme, and serves as a substrate in nerve impulse propagation.
What is meaningful sentence of impulse?
impulse is impulse
What are expressions for impulse?
Impulse = mv Impulse = Fmv
