1. The All-or-None Law states that the impulse is independent of the properties of the stimulus which started it. As long as the nerve cell is stimulated by an impulse of a certain minimal strength, it makes no difference how strong the exciting impulse is - just as a match or a blowtorch produces the same reaction in a fuse. It either fires or does not and there are no shades in between. The nerve impulse remains at the same strength as it travels along the nerve fiber, just as the spark remains at the same intensity as it moves along the fuse. The reason for this is evident in what has been said about a stimulus releasing energy in the fiber. It does not contribute energy.
Impulse size and speed: The nerve impulse varies with the size of the fiber. (It is proportional to the square of the fiber's diameter.
The size of the nerve impulse also depends on the condition of the fiber - being altered if drugged, deprived of oxygen, fatigued or in an abnormal state.
2. The Frequency Principle states that there are more impulses per second with the stronger stimulus than with the weaker stimulus. A stronger stimulus produces impulses more frequently than the weaker stimulus. The frequency of nerve impulses is thus a function of the intensity of the stimulus.

Sodium, potassium, and calcium are the important electrolytes involved in nerve impulses
Where does the spinal nerve take nerve impulses?
the spinal nerve sends nerve impulses away from the CNS

Do fish heads survive decapitation or is it just nerve impulses?
No, that is just nerve impulses
What is a mass of nerve tissue that receives and sends nerve impulses?
Neuron
Do Axons carries impulses toward the nerve cell body?
No, axons carry impulses away from the nerve cell body.
Impulses carried by the olfactory nerve are for the sense of?
Impulses carried by the olfactory nerve are for the sense of smell.
What information do nerve impulses require?
Nerve impulses do not carry information, they only carry impulses. It is the brain and spinal cord that interpret that impulse into information.
What nerve carries impulses from the nose?
Olfactory Nerve
