Reticular fibers are primarily responsible for forming a supportive framework within various tissues and organs. They are composed of collagen and have a branched structure that provides a network-like scaffold. This framework is crucial in maintaining the overall shape and integrity of soft tissues like the liver, spleen, lymph nodes, and bone marrow, ensuring that they can properly support cells and other structures. The supportive role of reticular fibers is especially important in organs that require a significant amount of structural integrity while still needing to allow for the movement and interaction of various cell types.

Other options describe different functions for various types of connective tissues. Connecting muscles to bones typically involves tendons, while elasticity in tissues is associated with elastic fibers. Anchoring epithelial cells pertains to the role of basement membranes or hemidesmosomes, not reticular fibers. Understanding the specific roles of various fiber types in connective tissue can help clarify their unique contributions to tissue architecture and function.
