Understand the definition of a symphysis: A symphysis is a type of cartilaginous joint where the bones are joined by fibrocartilage. It allows for slight movement and acts as a shock absorber.
Identify the characteristics of the knee joint: The knee joint is a synovial joint, specifically a hinge joint, which allows for movement such as flexion and extension. It is not joined by fibrocartilage.
Examine the sutures in the skull: Sutures are fibrous joints that connect the bones of the skull. They are immovable and are not joined by fibrocartilage.
Consider the elbow joint: The elbow joint is another synovial joint, specifically a hinge joint, allowing for flexion and extension. It is not a symphysis.
Analyze the intervertebral discs between vertebrae: These discs are composed of fibrocartilage and connect the vertebrae, allowing for slight movement and acting as shock absorbers. This is a classic example of a symphysis joint.
