Knee Anatomy

What are the main categories of structures that make up the knee joint?

• Bones, joints, ligaments, tendons, muscles, nerves, and blood vessels

• Bones, cartilage, muscles, and skin

• Ligaments, tendons, and blood vessels only

• Joints, nerves, and muscles

Which bones primarily meet to form the knee joint?

• Femur, Fibula, and Patella

• Femur and Tibia

• Tibia, Fibula, and Patella

• Femur, Tibia, and Patella

What is the primary function of articular cartilage in a joint?

• To connect bones to muscles

• To produce synovial fluid

• To absorb shock and provide a smooth surface for motion

• To provide side-to-side stability

What is the main function of the Anterior Cruciate Ligament (ACL) and Posterior Cruciate Ligament (PCL)?

• To prevent side-to-side motion of the knee

• To connect the patella to the tibia

• To control the front-to-back motion of the knee

• To lubricate the joint

What is the primary function of the menisci in the knee joint?

• To connect bones to bones.

• To spread weight across the tibial surface and protect articular cartilage.

• To attach muscles to bones.

• To increase the force exerted by quadriceps muscles.

What is the primary difference between ligaments and tendons?

• Ligaments connect muscles to bones, while tendons connect bones to bones.

• Ligaments connect bones to bones, while tendons connect muscles to bones.

• Ligaments provide sensation, while tendons provide muscle control.

• Ligaments are found in the knee, while tendons are found in the hip.

Which of the following are components of the extensor mechanism of the knee?

• Tibial nerve, common peroneal nerve, sciatic nerve.

• Popliteal artery, popliteal vein.

• Patella, patellar tendon, quadriceps tendon, quadriceps muscles.

• Hamstring muscles, hamstring tendons.

Which two nerves are the most important around the knee and split from the sciatic nerve?

• Femoral nerve and obturator nerve.

• Tibial nerve and common peroneal nerve.

• Sural nerve and saphenous nerve.

• Radial nerve and ulnar nerve.
