Thin filaments in muscle cells attach to the Z-discs, which are structures that anchor the filaments and help in muscle contraction. The Z-discs are located at the ends of the sarcomere, which is the basic contractile unit in muscle fibers. The attachment of thin filaments to the Z-discs allows for the sliding mechanism that is essential for muscle contraction.
