Diagram of cardiac muscle
WebCardiac excitation-contraction coupling (Cardiac EC coupling) describes the series of events, from the production of an electrical impulse (action potential) to the contraction of muscles in the heart. This process is of vital importance as it allows for the heart to beat in a controlled manner, without the need for conscious input. EC coupling results in the … WebCardiac muscles are found in the heart and they contract to pump blood. Skeletal muscle fibres are long and thin, ranging from 10 to 100 micrometres wide. Cardiac muscle fibres are thicker, ranging from 20 to 200 micrometres wide. Skeletal muscle is also arranged in bundles called fascicles, while the cardiac muscle is not.
