Q1. Which part of the radial head articulates with the radial notch of the ulna?
- Superior articular fovea only
- Articular circumference
- Radial tuberosity
- Styloid process
Q2. Which ligament encircles the head of the radius and holds it against the radial notch of the ulna?
- Transverse humeral ligament
- Ulnar collateral ligament of the wrist
- Annular ligament
- Coracoacromial ligament
Q3. Which muscle inserts onto the lateral surface of the distal radius near the styloid process?
- Triceps brachii
- Flexor carpi ulnaris
- Brachioradialis
- Biceps brachii
Q4. Which muscle inserts onto the lateral surface of the radius near the middle of the shaft and acts as a pronator?
- Pronator teres
- Supinator
- Brachialis
- Flexor carpi ulnaris
Q5. Which muscle wraps around and inserts onto the proximal third of the radius?
- Supinator
- Pronator quadratus
- Palmaris longus
- Flexor digitorum superficialis
Q6. Which muscle attaches to the anterior surface of the distal radius and is a major pronator of the forearm?
- Biceps brachii
- Supinator
- Pronator quadratus
- Anconeus
Q7. Which landmark on the posterior distal radius acts as a pulley for the extensor pollicis longus tendon?
- Dorsal tubercle
- Ulnar notch
- Radial tuberosity
- Styloid process
Q8. At which joint does the ulnar notch of the radius articulate with the head of the ulna?
- Humeroulnar joint
- Proximal radioulnar joint
- Acromioclavicular joint
- Distal radioulnar joint
Q9. During pronation, what happens to the radius relative to the ulna?
- The radius fuses with the ulna
- The radius crosses over the ulna
- The radius remains fixed while the ulna circles it
- The radius moves completely behind the humerus
Q10. Which sequence correctly identifies the major articulations of the radius from proximal to distal?
- Capitulum and proximal ulna, then distal ulna and proximal carpal bones
- Olecranon proximally, then metacarpals distally
- Trochlea and proximal ulna, then distal humerus and carpal bones
- Glenoid cavity proximally, then ulna distally
