What structure within a synovial joint is continuous with the periosteum of the articulating bones?

The fibrous capsule is an important structure within a synovial joint that is continuous with the periosteum of the articulating bones. The periosteum is a dense layer of vascular connective tissue that covers the outer surface of bones. The fibrous capsule consists of a tough layer of connective tissue that not only encloses the joint but also provides stability and support to the joint structure.

The continuity between the fibrous capsule and the periosteum ensures that the joint is well-integrated with the bone it articulates with, allowing for efficient load transfer during movement. This is crucial for maintaining joint stability and functionality during various activities.

The synovial membrane, on the other hand, lines the inside of the fibrous capsule and produces synovial fluid, which lubricates the joint. The joint cavity refers to the space between the articulating bones that is filled with synovial fluid, while hyaline cartilage covers the ends of the bones that make up the joint. While all of these structures play significant roles in the function of synovial joints, none of them establish the same direct connection to the periosteum that the fibrous capsule does.
