---

The sarcomere is the fundamental contractile unit of a muscle fiber, lying between two successive Z-lines. Its structure consists of alternating thick and thin filaments organized in a precise arrangement. The Z-lines form the boundaries of each sarcomere and serve as anchoring points for thin filaments, which are primarily composed of actin. The thick filaments, made up of myosin, are situated in the center of the sarcomere. The overlap of these filaments creates distinct bands. The A-band corresponds to the length of the thick _____________ _______ _________ _____ ___ ________ _______ __________ ________ ___________ _________ ____________ _____________ ___ _______.
