Action Potential for Heart Muscle Compared to Skeletal Muscle: A Detailed Comparison
The action potential is a fundamental electrical event that drives muscle contraction, with distinct differences between heart and skeletal muscle that reflect their unique functions. This diagram compares the cardiac muscle action potential and skeletal muscle action potential, highlighting variations in duration, ion involvement, and refractory periods that support the heart’s rhythmic pumping versus skeletal muscle’s voluntary action. Exploring this image offers valuable insights into the electrophysiological adaptations of these muscle types.
