Final answer:
The central fibrous domain is flanked on each side by fibrous connective tissues, muscle fiber organization, or cellular components.
Step-by-step explanation:
The central fibrous domain mentioned in the question is likely referring to a part of a molecular structure that is flanked by various other components. Without a direct reference to a specific molecular complex, the information provided relates to different aspects of fibrous connective tissue and the organization of muscle fibers as well as to the structural arrangement in immune receptors like the T cell receptor.
In the context of connective tissue, structures such as the interosseous membrane, which connects bones or the arrangement of collagen in tendons could be considered alongside the organization of fibrous proteins in other structures such as centrosomes or intermediate filaments in cells.
