24
Q

What type of joint is the sternoclavicular joint?

25
What type of joint is the Acromioclavicular Joint?
Plane joint
26
What ligaments help form the sternoclavicular joint?
Anterior Sternoclavicular ligament, Posterior SC, Interclavicular & Costoclavicular
27
AC joint is weak and is easily injured by a direct blow. True or false?
True
28
What happens with a Dislocation of AC joint?
When both AC and coracoclavicular ligaments are torn, the shoulder separates (falls away) from the clavicle because of the weight of the upper limb
29
Where is the Glenohumeral Joint?
Attached medially to margin of glenoid cavity & laterally to anatomical neck of humerus Encloses proximal attachment of long head of biceps brachii (supraglenoid tubercle)
30
Where are the bursa's on the Glenohumeral Joint?
Subscapular bursa Between tendon of subscapularis and neck of scapula Communicates with cavity of shoulder joint Extension of glenohumeral joint cavity Subacromial bursa (Subdeltoid bursa) Large bursa inferior to acromion, coracoacromial ligament & deltoid muscle Facilitates movement of supraspinatus tendon under coracoacromial arch and of the deltoid over the capsule of glenohumeral joint and greater tubercle of humerus
31
What are the muscles of the rotator cuff?
Supraspinatus, Infraspinatus, teres minor and subscapularis.
32
In a dislocation of the GH joint, Due to coracoacromial arch & rotator cuff (superior stability), most dislocations of humeral head are...?
Downward
33
Where is the weakest part of the clavicle?
junction of its middle & lateral thirds
34
What is the ligament at the Proximal Radioulnar Joint?
Annular
35
What ligaments are at the Distal Radioulnar Joint?
Anterior and Posterior
36
What ligaments are in the wrist joint?
Palmar radiocarpal Dorsal radiocarpal Ulna Collateral Radial Collateral
37
What type of joint is the wrist?
Condyloid joint
38
What ligaments are in the intercarpal joints?
Anterior Posterior Interosseous
39
What ligaments are in the carpometacarpal and intermetacarpal joints?
Anterior and Posterior Carpometacarpal Anterior and Posterior Metacarpal Posterior Interosseous
40
What ligaments are in the metacarpophalangeal and interphalangeal joints?
Collateral, Palmar and Transverse Metacarpal
41
What is superficial fascia?
composed of loose fatty highly variable connective tissue Is a thermal regulator and provides protection for the skin from boney prominences
42
What is deep fascia?
Dense, organised connective tissue layer that invests deep structures such as the muscles E.g. Medial and lateral intermuscular septa divides the arm into the anterior (flexor) and posterior (extensor) fascial compartments
43
Where is the Apex of the Axilla?
Between first rib, clavicle and superior edge of subscapularis
44
Where is the base of the Axilla?
Skin, subcutaneous tissue and axillary fascia
45
Where is the anterior wall of the Axilla?
Pectoralis major and minor and associated fascia
46
Where is the posterior wall of the Axilla?
Scapula and subscapularis, and inferiorly by teres major and latissimus dorsi
47
Where is the medial wall of the Axilla?
Thoracic wall (1st-4th ribs and intercostal muscles), serratus anterior
48
Where is the lateral wall of the Axilla?
Intertubercular groove of humerus
49
What are the 5 axillary lymph nodes?
pectoral (anterior) lateral posterior central apical
50
What is the branch from the first part of the Axillary artery?
Superior Thoracic
51
What are the branches from the second part of the Axillary artery?
thoracoacromial lateral thoracic
52
What are the branches from the third part of the Axillary artery?
subscapular anterior humeral circumflex posterior humeral circumflex
