In the absence of joint spaces (cavities) and bones fused together, body movements would be null or reduced.
Explanation:
The joints are the spaces where two bones meet, with cartilaginous tissue - articular cartilage and ligaments - to allow elasticity and body movements.
The articular cavities are spaces where bone union occurs through ligaments, surrounded by an articular capsule and upholstered inside by a membrane that produces liquid, the membrane and synovial fluid, respectively. These joints are usually found in the mobile body segments.
