Answer 6

acromioclavicular joint

Question 7

which end is bulbous

Answer 7

sternal end

Question 8

which end is flattened

Answer 8

acromial end

Question 9

conoid tubercle

Answer 9

clavicle
- useful landmark for inferior side
- attachment for conoid ligament
- near acromial end
- posterior side of inferior surface
- small stuck out lump

Question 10

impression for the costoclavicular ligament

Answer 10

• attachment of clavicle to costal cartilage of first rib
• sometimes not really visible, look for rough patch near sternal end

Question 11

trapezoid line

Answer 11

• runs obliquely from conoid tubercle to lateral/acromial end
• attachment of trapezoid ligament

Question 12

subclavian groove

Answer 12

• indentation between conoid tubercle and impression for costoclavicular ligament
• subclavius muscle attachment
• on inferior surface

Question 13

subscapular fossa

Answer 13

indentation/pit in the centre of the anterior surface below scapular notch

Question 14

coracoid process

Answer 14

curved hook like projection above lateral angle
protrudes anteriorly and slightly laterally

Question 15

scapular notch

Answer 15

groove medial to coracoid process
location of the suprascapular nerve
small notch above subscapular fossa

Question 16

glenoid cavity/fossa

Answer 16

shallow hollow for articulation with the humerus
located on lateral end
visible from side on in median plane

Question 17

spine of scapula

Answer 17

posterior protrusion links to acromion

fossa above spine
appears to protrude cranially

Question 19

infraspinous fossa

Answer 19

fossa below spine

Question 20

acromion

Answer 20

widened flat part lateral to spine
moves slightly cranially and laterally from spine

intertubercular/bicipital groove

Answer 28

groove/pit between the two tubercles

Question 29

humeral shaft

Answer 29

main body of humerus
