The sliding filament model explains how muscle contraction occurs at the microscopic level. Within each sarcomere, thin actin filaments slide past thick myosin filaments. When stimulated, myosin heads bind to actin and pull them inward, shortening the sarcomere. This process is powered by ATP and regulated by calcium ions. As many sarcomeres shorten simultaneously, the entire muscle fiber contracts. Sliding Filament Model Muscle Ultrastructure Diagram - Chart - diagrams and charts with labels.
