| Question | Answer |
|---|---|
| Acromioclavicular ligament | acromion-->distal clavicle |
| articular disc | sometimes abscent |
| Coracoclavicular ligament | Coracoid process→distal clavicle |
| coracoacromial ligament | Coracoid process→acromion |
| superior transverse scapular ligament | over scapular notch |
| coracohumeral ligament | Superiorly and anteriorly reinforces articular capsule of shoulder joint |
| transverse humeral ligament | Attaches to lesser and greater tubercles, crosses over bicipital groove, helps hold tendon of long head of biceps brachii in bicipital groove |
| ulnar collateral ligament | Attaches to medial epicondyle and proximal ulna; medially reinforces articular capsule of elbow joint |
| radial collateral ligament | Attaches to lateral epicondyle and proximal radius; laterally reinforces articular capsule of elbow joint |
| annular ligament | Attaches to ulna, loops around head of radius; holds radial head in radial notch of ulna |
| interosseous membrane | between radius and ulna |
| palmar radiocarpal ligament | Strengthens capsule on palmar aspect of radiocarpal joint |
| palmar ulnocarpal ligament | Strengthens capsule on palmar aspect of radiocarpal joint |
| dorsal radiocarpal ligament | Strengthens dorsal aspect of radiocarpal joint |
| ulnar collateral ligament (wrst) | medial reinforcement of wrist |
| radial collateral ligament (wrist) | lateral reinforcement of radius |
| articular disc (wrist) | at distal end of ulna |
