Smooth muscle is composed of far smaller fibers – usually 1 to 5 micrometers in diameter and only 20 to 500 micrometers in length. | Smooth muscle is composed of far smaller fibers – usually 1 to 5 micrometers in diameter and only 20 to 500 micrometers in length. | ||
In contrast, skeletal muscle fibers are as much as 30 times greater in diameter and a hundred times longer. | In contrast, skeletal muscle fibers are as much as 30 times greater in diameter and a hundred times longer. | ||
The fundamental principles of contraction are almost the same in skeletal muscles and smooth muscles. However the structural arrangement is different in both groups.<ref>Guyton, | The fundamental principles of contraction are almost the same in skeletal muscles and smooth muscles.
