Thin and thick filaments are organized into repeating units called sarcomeres. Dark lines called Z-lines mark off the boundaries of each sarcomere. Thin filaments attach to the Z-lines at both ends of the sarcomere, while thick filaments are unattached. Each myofibril contains thousands of sarcomeres.
A sarcomere is the most basic functional unit of a muscle fiber, which makes up striated muscle.uscle movement happens when the filaments slide across each other within the muscular bands. The sliding filament model is made possible by the interaction of the actin and myosin proteins within the filaments.
