A longitudinal section of a sarcomere in a relaxed state and label the Z lines, thin filaments, and thick filaments. Introduction: Sarcomere is the smallest unit of a muscle fiber. The filaments of actin and myosin are constitutively known as a sarcomere. Multiple numbers of sarcomere are joined together to form the structure of a muscle. They join together with each other in the end-to-end direction, resulting in the formation of “myofibril”.
