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.
  cardiac and skeletal muscles have one thing in common, that is they are both striated in contrast to the smooth muscles commonly found in the GIT. however the main diffe â¦ rence between them is that cardiac muscles function involuntarily while skeletal muscles are under conscious control.keletal muscles are voluntary muscles, meaning that they are used in actions which a person consciously controls, such as lifting a dolphin or biting into a book. Smooth muscles are used in involuntary actions, which a person doesn't consciously control, like digesting food.
