What is the primary ligament that resists valgus force at the elbow?

• Annular Ligament

• Radial collateral ligament

• Ulnar collateral ligament

• Interosseous membrane

Which elbow joint allows for both flexion/extension and pronation/supination?

• Humeroulnar

• Humeroradial

• Distal radioulnar
