Heart Excitation. Heart Excitation. Cardiac muscle cells are excitable (with electrical stimulation they will contract, leading to the contraction of the heart) Contraction of heart leads to pumping of blood.

Muscle excitation. The excitation of muscles depend on the arrival of a stimulus to the muscle cell membrane to generate an excitation ( action potential ) in the muscle membrane.
