WebThe sarcomere is defined as the region of myofilament structures between two Z-lines. The distance between Z-lines (i.e., sarcomere length) ranges from about 1.6 to 2.2 μ in human hearts. The sarcomere is composed of thick and thin filaments – myosin and actin, respectively, along with a titin that anchors the myosin to the Z-lines.
