Smooth muscles contract very slowly, whereas skeletal muscles can contract at different rates. Skeletal muscles can be composed of fast-contracting fibers, slow-contracting fibers or a mixture of both.
One of the main differences that can be seen is that cardiac muscles are involuntarily controlled, whereas the somatic nervous system controls the ovement of the skeletal muscles. Cardiac muscles and skeletal muscles are also different in their shape.While the cardiac muscles are semi-spindle, the skeletal muscles are cylindrical in shape. Another difference is that the cardiac muscles are short in comparison to skeletal muscles.. Cardiac muscles are involuntarily controlled, whereas the somatic nervous system controls the movement of the skeletal muscles. 2. While the cardiac muscles are semi-spindle, the skeletal muscles are cylindrical in shape. 3.
