Skeletal muscle fibers are highly specialized cells designed for contraction and movement. At the molecular level, each fiber is composed of myofibrils, which are cylindrical structures running parallel along the length of the cell. Myofibrils are made up of repeating units called sarcomeres, which are the functional contractile units of muscle. Sarcomeres contain an organized arrangement of thick and thin filaments. Thick filaments are primarily composed of myosin, a motor protein with heads that interact with actin to generate force. Thin filaments consist mainly of actin, along with regulatory
