Quizplus · Accepted Answer

The joint capsule is the structure that surrounds a diarthrotic or synovial joint. It is composed of a tough fibrous outer layer and a synovial membrane on the inner layer, which produces synovial fluid to lubricate and nourish the joint. The meniscus is a piece of cartilage found in some joints, while a bursa is a small fluid-filled sac that helps reduce friction between tissues. An alveolus is a small air sac found in the lungs.
