  Anterior ligament, posterior ligament, oblique ligament.
- B.
  
  Anterior bundle, transverse ligament, posterior bundle.
- C.
  
  Transverse ligament, medial bundle, annular ligament (lateral portion).
2.

The radius articulates with the Trochlea of the Humerus.
- A.
  
  True
- B.
  
  False
3.

The radius is a major forearm bone contributing to the wrist joint. When the radius moves, the wrist moves with it.
- A.
  
  True
- B.
  
  False
4.

Statement: The annular ligament of radius is attached to the anterior and posterior margins of the notch.The ligament is more “cup-shaped” than “ring-shaped”, therefore the head of the radius cannot slip upwards.
- A.
  
  True
- B.
  
  False
5.

Which bundle tightens in extension? (MCL-complex)
- A.
  
  Anterior
- B.
  
  Posterior
- C.
  
  Transverse
6.

The radial head is considered a second stabilizer in the elbow with an intact MCL complex.
- A.
  
  True
- B.
  
  False
7.

In extension: resistance to valgus stress is shared equally by MCL, capsule and joint articulation
- A.
  
  True
- B.
  
  False
8.

For resisting varus stress in extension, the main stabilizer is the LCL.
- A.
  
  True
- B.
  
  False
9.

11.

A triangular articular disc is attached to the styloid process of the radius (with its apex), and to the ulna (with its base).
- A.
  
  True
- B.
  
  False
12.

In supination, the ulna and radius are:
- A.
  
  Parallel
- B.
  
  Crossed
- C.
  
  In 50 degrees supination, 50 degrees pronation
13.

When the bones of the forearm are crossed, it means that the arm is pronated.
- A.
  
  True
- B.
  
  False
14.

Most activities are accomplished within the functional range of 50 degrees pronation, and 50 degrees of supination.
- A.
  
  True
- B.
  
  False
15.

Clinically patients can tolerate up to 40 degrees of flexion contractures. More than this, significantly increases complaints.
- A.
  
  True
- B.
  
  False
16.
