A sarcomere (Greek sarx flesh, meros part) is the basic unit of striated muscle tissue. Skeletal muscles are composed of tubular muscle cells (myocytes called muscle fibers) which are formed in a process known as myogenesis. Muscle fibers are composed of tubular myofibrils.he myosin head also binds to ATP, which is the source of energy for muscle movement. Myosin can only bind to actin when the binding sites on actin are exposed by calcium ions. Actin molecules are bound to the Z line, which forms the borders of the sarcomere. Other bands appear when the sarcomere is relaxed.
A sarcomere is the most basic functional unit of a muscle fiber, which makes up striated muscle.op 10 facts about the world. A sarcomere is the basic functional unit of striated muscle, which is to say, itâs the basic building block of most muscle cells. In the human body, each muscle is made up of multiple bundles of muscle fibers.
