Q1. Which part of the coracoclavicular ligament is located more medially?
- Superior acromioclavicular ligament
- Trapezoid ligament
- Conoid ligament
- Coracoacromial ligament
Q2. Which part of the coracoclavicular ligament is located more laterally?
- Trapezoid ligament
- Coracoacromial ligament
- Costoclavicular ligament
- Conoid ligament
Q3. The conoid ligament attaches to which landmark on the clavicle?
- Conoid tubercle
- Sternal articular surface
- Deltoid tubercle
- Subclavian groove
Q4. The trapezoid ligament attaches to which landmark on the clavicle?
- Impression for the costoclavicular ligament
- Trapezoid line
- Subclavian groove
- Conoid tubercle only
Q5. Which structure may partially or completely divide the acromioclavicular joint cavity?
- Subacromial bursa
- Articular disc
- Glenoid labrum
- Long head of biceps tendon
Q6. Why is movement at the acromioclavicular joint important during elevation of the upper limb?
- It produces flexion and extension at the elbow
- It locks the scapula completely against the thoracic wall
- It allows the scapula to adjust and rotate relative to the clavicle
- It permits the humeral head to rotate inside the ulna
Q7. Which structure provides major vertical stability to the acromioclavicular region?
- Coracoclavicular ligament
- Coracoacromial ligament
- Transverse humeral ligament
- Annular ligament
Q8. Which ligament is more directly associated with horizontal stability of the acromioclavicular joint?
- Acromioclavicular ligament
- Transverse scapular ligament
- Costoclavicular ligament
- Coracoacromial ligament
Q9. Which muscles attach near and help reinforce the superior aspect of the acromioclavicular region?
- Deltoid and trapezius
- Pronator teres and supinator
- Biceps brachii and brachialis
- Latissimus dorsi and teres major
Q10. Which statement best describes the relationship between the acromioclavicular and sternoclavicular joints during shoulder girdle movement?
- Only the acromioclavicular joint moves during scapular rotation
- They move in coordination to position the scapula during upper limb movement
- Only the sternoclavicular joint moves during arm elevation
- The two joints normally prevent all scapular movement
