Muscle Contractions And Cardiac Muscles

Striations marked by transverse dark and light bands created by the overlapping patterns in cytoplasmic protein filaments can be seen in skeletal and cardiac muscle which differ from smooth muscle which are non-striated. This striations cause muscle contractions in the heart and skeletal muscle.
Skeletal muscle is voluntary which differs from smooth and cardiac muscle which are both involuntary muscle meaning the tissue cannot be controlled consciously which is why people can’t control how the heart beats or respiration in the lungs but you can control body movements.
Cardiac muscle tissue differs from smooth and skeletal muscle by the presence of intercalated discs; junctions that allow electrical impulses to travel efficiently from one cell
