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.
The sarcomere is the fundamental unit of muscle structure. Its capacity for contraction is the essential trait that makes muscles work.It has two primary components (1) thin filaments (each of which contains two strands of actin and a single strand of regulatory protein); and (2) thick filaments made of myosin (see diagram right).uring muscle contraction the thick filaments quickly slide along the thin filaments to shorten the myofibrils. The myofilaments themselves, however, do not contract. This is the action that give muscles their physical force.
