Fill in the Blank QuestionFill in the blank question.A joint consists of the convex surface of one bone fitting into the concave surface of another.

The correct term to fill in the blank is "synovial joint."

Explanation

A synovial joint is a highly mobile joint characterized by a fluid-filled cavity known as the synovial cavity. In these joints, the convex surface of one bone fits into the concave surface of another, allowing for a greater range of motion. Examples include the shoulder joint, hip joint, and knee joint.

Synovial joints are supported by various structures such as ligaments, which connect bones to other bones, and tendons, which attach muscles to bones. Additionally, they are lubricated by synovial fluid, which reduces friction during movement and nourishes the cartilage. Because of their structure and function, synovial joints are essential for facilitating movement in the body, enabling activities such as walking, running, and other physical activities.
