Joint Anatomy and Stability Quiz

The shoulder joint allows for a wide range of motion due to its ball-and-socket structure.

A bursa is a small fluid-filled sac near a joint that helps reduce friction and cushion the joint.

The elbow joint is formed by the articulation of the humerus, radius, and ulna bones.

Ligaments connect bone to bone in a joint and help stabilize the joint.

The glenoid fossa is the bony prominence on the shoulder blade that forms the socket of the shoulder joint.

The rotator cuff muscles stabilize the shoulder joint and facilitate various arm movements.

The ACL connects the femur to the tibia and is often injured during sports that involve sudden stops or changes in direction.

Cartilage in joints does not produce synovial fluid; instead, it provides a smooth surface for joint movement and absorbs shock.

Cartilaginous joints are not synovial joints; they are connected by cartilage and do not have a synovial cavity.
