- A.
Saddle joints
- B.
Hinge joints
- C.
Condyloid
- D.
Elipsoid
- 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.ROM of pronation / supination is =
- A.
140 - 150 degrees in total.
- B.
155 - 165 degrees in total.
- C.
170 – 185 degrees in total.
- 17.The pronator quadratus is the strongest pronator.
- A.
True
- B.
False
- 18.The supinators are stronger than the pronators.
- A.
True
- B.
False
- 19.The wrist joint is an example of:
- A.
Hinge joint
- B.
Ball and socket joint
- C.
Ellipsoid joint
- D.
Saddle joint

Option 4
- 22.In the anatomical position the scaphoid is opposite the lateral area of the radius, and the lunate opposite the medial area + disc.
- A.
True
- B.
False
- 23.The radial collateral ligament extends from the radial styloid process to the;
- A.
Lunate.
- B.
Trapezoid.
- C.
Scaphoid.
- 24.Which ligament extends from the ulnar styloid process to the triquetrum and pisiform.
- A.
