Question 19

What is the intrinsic ligament of the TMJ?

Answer 19

Question 20

what does the lateral ligament of the TMJ do?

Answer 20

• Intrinsic ligament
  
  • Is a thickening of the lateral joint capsule
  • Strengthens the TMJ laterally
  • Helps prevent posterior dislocation of the joint

Answer 22

• Extrinsic ligament
  
  • From the spine of the sphenoid to the lingula of the lingula of the mandible
    Acts as a fulcrum for movement of the TMJs and helps limit the amount of movement occurring at the joints
