The space between two Z lines in a muscle fiber constitutes a sarcomere. A sarcomere is the functional unit of a muscle fiber and is responsible for muscle contraction. It is defined as the segment between two Z lines, which are structures that anchor the actin filaments. Within a sarcomere, there are various components, including actin and myosin filaments, as well as regulatory proteins like tropomyosin and troponin. Contraction of the sarcomere occurs when the actin and myosin filaments slide past each other, resulting in the shortening of the sarcomere and overall muscle contraction.
