actin
The outer boundaries of the sarcomere are defined by the Z-discs or Z-lines, which mark the ends of the sarcomere unit. These Z-discs separate one sarcomere from the next and provide attachment points for actin filaments.
The sarcomere is the basic unit of muscle structure, located between two Z discs. It is composed of actin and myosin filaments arranged in a highly organized pattern, giving muscle its striated appearance. During muscle contraction, the sarcomere shortens as the actin and myosin filaments slide past each other.
The sarcomere is the basic unit of muscle structure and is located within the myofibrils of skeletal muscle cells. It runs from one Z disc to the next Z disc and is responsible for muscle contraction by sliding the actin and myosin filaments past each other.
It is a section of the Sarcomere that stretches from one end of the Myosin filament to the other, and also includes parts of the Actin filaments that overlaps it.
The two main filaments composing the sarcomere are action and myocin.
Yes, sarcomere thick filaments are linked laterally by proteins of the M line, not the Z line. The Z line anchors the thin filaments and separates one sarcomere from the next.
The outer boundaries of the sarcomere are defined by the Z-discs or Z-lines, which mark the ends of the sarcomere unit. These Z-discs separate one sarcomere from the next and provide attachment points for actin filaments.

One of the functional units of a myofibril is the sarcomere. The word sarcomere comes from the Greek words sarx, meaning flesh, and meros, meaning part.
