WebMyosin and actin filaments are laid side by side to form the cylindrical sarcomere. Sarcomeres are positioned end to end to form a myofibril.Each myofibril is surrounded by the sarcoplasmic reticulum, the specialized endoplasmic reticulum of the myocyte.The lumen of the sarcoplasmic reticulum is filled with Ca 2+ ions. Lodged between the … WebMyofilament. Myofilaments are the three protein filaments of myofibrils in muscle cells. The main proteins involved are myosin, actin, and titin. Myosin and actin are the contractile proteins and titin is an elastic protein.
