Answer 2

Answer:

• A nerve impulse is the way nerve cells (neurons) communicate with one another. Nerve impulses are mostly electrical signals along the dendrites to produce a nerve impulse or action potential.

• The action potential is the result of ions moving in and out of the cell. Specifically, it involves potassium (K+) and sodium (Na+) ions. The ions are moved in and out of the cell by potassium channels, sodium channels and the sodium -potassium pump.

In simple words,

• The signal that travels along the length of a nerve fiber and ends in the release of neurotransmitters. Nerve impulses are the means by which information is transmitted along the neuron and throughout the nervous system.
