Question 7

List the bony points on the scapula

Answer 7

3 borders (medial, lateral and superior), 2 angles (superior and inferior), 2 surfaces (anterior and posterior), 3 processes (coracoid, acromion, spine), 3 fossa (supraspinatus, infraspinatus and subscapularis), 1 cavity (glenoid)

Question 8

Answer 8

Manubrium, xiphoid process, body, jugular notch and sternal angle

Question 9

What type of joint is the acromioclavicular and what are the movements available here?

Answer 9

Synovial plane joint with small glides of acromion on clavicle

Question 10

What are the articulations of the acromioclavicular joint?

Answer 10

Small oval facets on lateral clavicle and medial acromion, covered with fibrocartilage and an intra-articular disc

Question 11

Describe the joint capsule and ligaments of the acromioclavicular joint

Answer 11

Capsule attached to articular margins and strengthened by fibres above and below. Ligaments are acromioclavicular and coracoclavicular (trapeziod and conoid)

Answer 12

Synovial saddle joint with small glides

Question 13

Answer 13

Convex clavicle that’s larger and covered with fibrocartilage articulating with concave manubrium covered with hyaline cartilage (and costal cartilage of first rib), also an intra-articular disc

Question 14

Describe the joint capsule and ligaments of the sternoclavicular joint

Answer 14

Capsule surrounds joint and is strengthened by anterior and posterior sternoclavicular ligaments and interclavicular ligament. Extracapsule ligament - costoclavicular
