Multiple Choice

Imagine you're a doctor and a patient comes to you because of pain in their knee joint. You find that there is not enough synovial fluid present in their knee's synovial cavity, leading to friction when the knee moves. Which of the following structures in the knee joint is not functioning correctly?

Bursae.

Articular cartilage.

Articular capsule.

Synovial membrane.

Verified step by step guidance

Begin by understanding the role of synovial fluid in the knee joint. Synovial fluid is a viscous liquid that lubricates the joint, reducing friction between the articular cartilage of synovial joints during movement.

Identify the structures involved in the production and maintenance of synovial fluid. The synovial membrane is responsible for secreting synovial fluid into the synovial cavity.

Evaluate the function of each structure listed in the options: Bursae, Articular cartilage, Articular capsule, and Synovial membrane. Determine which structure directly affects the presence of synovial fluid.

Recognize that the synovial membrane lines the inner surface of the articular capsule and is crucial for producing synovial fluid. If there is insufficient synovial fluid, the synovial membrane may not be functioning properly.

Conclude that the synovial membrane is the structure not functioning correctly, as it is directly responsible for the secretion of synovial fluid, which is lacking in the patient's knee joint.
