Skeletal muscle tissue is attached to our bones. It is striated; that is, the fibers (cells) contain alternating light and dark bands (striations) that are perpendicular to the long axes of the fibers. Skeletal muscle tissue can be made to contract or relax by conscious control (voluntary).nd how do we know what type of muscle fibers we have in the muscle we are training; by knowing what muscle fibers a specific muscle has, can take the guess work out of what type of training that specific muscle requires.
