Final answer:
The organization of contractile elements in muscle tissue involves actin and myosin filaments, cross-bridges, and the sliding filament model of muscle contraction. The actin and myosin filaments make up the myofibrils within muscle fibers, while the cross-bridges.
Step-by-step explanation:
The organization of contractile elements in muscle tissue involves actin and myosin filaments, cross-bridges, and the sliding filament model of muscle contraction. The actin and myosin filaments make up the myofibrils within muscle fibers, while the cross-bridges are formed by the binding and detachment of myosin to actin. In the sliding filament model, the actin filaments slide past the myosin filaments, causing the muscle fiber to shorten and generate contractile force. The energy for cross-bridge formation and filament sliding is provided by ATP.
