What is the difference between cardiac and skeletal muscle cells?

-The skeletal muscle has long and cylindrical cells. The cardiac muscle cells are short and together they form a branch.

-The heart muscle fibers have only one nucleus in the center. The skeletal muscle fibers are multinucleated.

-The skeletal muscle is voluntary and the cardiac is involuntary.

- Sarcoplasma and glycogen are more abundant in the heart muscle.

-The cardiac muscle is longitudinal striated and the skeletal is transverse striated

its temperature is increasing. this causes molecular vibrations to increase.
