Synovial joints, the lubricated cavity that lets the bones in our shoulders, knees, and elbows slide smoothly against each other, provide freedom of movement to all vertebrates. Scientists have known ...

Synovial joints have synovial fluid in the joint cavity that lubricates or 'oils' the joint so it moves smoothly. Synovial fluid is made by the synovial membrane. In synovial joints, the ends of ...

A synovial joint allows bones or cartilage to slide past each other with the aid of a lubricated cavity between them. These joints are present in land vertebrates and bony fish, suggesting this ...

Among them, synovial joints—characterized by a fluid-filled cavity that allows smooth articulation—are crucial for mobility in all tetrapods, including humans. Fossil evidence shows that early ...
