Describe at least three distinguishing features of synovial joints.

Synovial fluid

ligaments

Explanation:

1) the ends of the bones of the synovial joints are covered with a connective tissue filled with synovial fluid

2) the outer surface of the joints contains ligaments that strengthen the joint and holds it in position thereby increasing flexibility

3) the synovial fluid present in the synovial cavity, lubricates the ends of the bones and reduces friction
