Striated muscle tissue, such as the tissue of the human biceps muscle, consists of long fine fibres, each of which is in effect a bundle of finer myofibrils. ... Within each myofibril are filaments of the proteins myosin and actin; these filaments slide past one another as the muscle contracts and expands.
