how would the function of synovial joints be changed if they lacked joint cavities and the bones were united instead? Explain.
Anettt [7]

Answer:

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.

<em><u>If the joint cavities did not exist, and the joints occurred between bone and bone, body mobility would not be possible</u></em>. In the case of the skull bones, they do not have joint space, since their function is the protection of the organs of the central nervous system, not movement.
