The sliding filament theory is the explanation for how muscles produce force (or, usually, shorten). It explains that the thick and thin filaments within the sarcomere slide past one another, shortening the entire length of the sarcomere.

The sliding filament theory describes a process used by muscles to contract. Myosin is a molecular motor that acts like an active ratchet. Chains of actin proteins form high tensile passive 'thin' f...

The sarcomere shortens because the thin filaments slide past the thick filaments. In 3D each thick myofilament is surrounded by six thin myofilaments arranged in a hexagonal pattern. The 3D arrangement of sliding myofilaments is the microscopic basis of muscle contraction...

At the start of contraction, stored calcium ions are released into the cytoplasm. Calcium ions expose binding sites on the actin molecules. Globular heads on the myosin can bind to these Repeated binding and release moves the filaments relative to one another and as this occurs simultaneously in many sarcomeres,

Energy from is used to break the , the cross bridge, and allow the cross bridge to form a new bond with another further down the actin filament. This cycle continues until the muscle is complete. Then ATP is used to cause active to move the calcium ions out of the muscle fiber causing of the muscle.
