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 short answer is-no pun intended-muscles shorten when they contract. This begs the question of how muscles shorten and, thus, contract. To answer this question, we must first examine the components of the sarcomere, which is the fundamental functional unit of striated muscle-that is, skeletal and cardiac muscle.To say that the sarcomere is the functional unit means that all the components needed for contraction are contained within each sarcomere.hile each sarcomere is small, several sarcomeres added together span the length of the muscle fiber. Each sarcomere consists of thick and thin bundles of proteins referred to as myofilaments. If we magnify a portion of the myofilaments, we can identify the molecules that compose them.
