What happens in a nerve impulse?

The transmission of a nerve impulse along a neuron from one end to the other occurs as a result of electrical changes across the membrane of the neuron. The membrane of an unstimulated neuron is polarized—that is, there is a difference in electrical charge between the outside and inside of the membrane.

Likewise, how does a nerve impulse works?

Neurons, or nerve cells that carry nerve impulses, are made up of the cell body, the axon, and several dendrites. Signals move across the synapse, the place where the axon of one neuron meets the dendrite of another, using chemicals called neurotransmitters.

What is a nerve impulse and how is it generated?

cell neuron ions membrane. When a stimulus is strong enough, a nerve impulse is generated in an "all or none" response which means that a stimulus strong enough to generate a nerve impulse has been given. The stimulus triggers chemical and electrical changes in the neuron.

Is a nerve impulse the same thing as an action potential?

An action potential is the change in voltage across a cell membrane as a nerve impulse is transmitted. So basically as a nerve impulse is transmitted the voltage will change.and this change is called the action potential. Whereas nerve impulses are messages which are sent to the brain or muscles.
