shoulder

Question 1

sternoclavicular joint

Answer 1

Synovial saddle joint

Question 2

articular surface

Answer 2

medial end of clavicle covered in fibrocartilage
upper margin of the manubrium sterni covered in hyaline cartilage
costal cartilage of first rib
intra-articular fibrocartilage disc provides conguence

Question 3

capsule

Answer 3

surounds the joint
strengthened by anterior sternoclavicular ligament
posterior sternoclavicular ligament
interclavicular

Question 4

synovial membrane

Answer 4

2 synovial membranes
medial membrane attaches to the articular margins of the sternum and to medial margins of the disc
lateral membrane attaches to the articular margins of the medial end of the clavicle and the lateral intra-articular disc

Question 5

intra-articular disc

Answer 5

flat and circular fibrocartilage disc
acts as a shock absorber
attached to joint capsule

Question 6

anterior sternoclavicular ligament

Answer 6

anterior surface of medial end of clavicle to the anterior superior manubrium and costal cartilage of 1st rib

Question 7

posterior sternoclavicular ligament

Answer 7

posterior surface of medial ed of clavicle to the posterior surface of the superior manubrium

Question 8

intrerclavicular ligament

Answer 8

strengthens the capsule superior-ally

attaches left clavicle to right clavicle spanning the strernal notch

Question 9

costoclavicular ligament

Answer 9

anterior and posterior fibres from first costal cartilage to the medial end of clavicle

compensates for weakness of inferior capsule
limits elevation

Question 10

Acromioclavicular joint

Answer 10

a synovial plane joint

Question 11

articular surface

Answer 11

small oval facet on acromion of scapula facing anteromedialy slightly concave

oval facet on clavicle posterolaterally slightly convex

covered in fibrocartilage

Question 12

capsule

Answer 12

loose fibrous capsule attached to articular margins surround the joint
strengthemed superioolly and inferioally by Acromioclavicular ligament

Question 13

synovial membrane

Answer 13

lines the inner surface of the capsule attached to articular surface

Question 14

Disc

Answer 14

wedges-shaped fibrocartilaginous disc attached to capsule and articular surface

Question 15

acrominoclavicular ligament

Answer 15

superior lateral end of clavicle to superior surface of acromion

Question 16

coracoclaviclar ligament

Answer 16

provides join stabilty

trapezoid part
from the corocoid process to trapizoid line of the infreior surface of the clavicle
limits backwards movement of the scapula

conoid part root of the coracoid process to the conoid tubercle of the infreior surface of the clavicle
limits forward movement of the scapula

Question 17

clavicle

Answer 17

s shaped
medial end convex anteriorally

lateral concave anteriorally

deltoid tubercle 
conoid tubercle
trapezoid line
subclavian groove 
costal tuberosity

Question 18

scapula

Answer 18

medial inferior and lateral border and angle
costal anterior surface 
dorsal posterior surface
spine of the scapula
glenoid process
acromion process
coracoid process
subscapula fossa 
suprascapular notch
infraspinous fossa
supraspinous fossa

Question 19

protraction

Answer 19

lateral movement of the scapula
acromion moves forwards over clavicular facet to limit
clavicule moves backwards over sternal facet medial end of clavicle moves as unit with disc

Question 20

retatracion

Answer 20

medial movement of the scapula
acromion movesbackwards over clavicular facet to limit
clavicule moves forewards over sternal facet medial end of clavicle moves as unit with disc

Question 21

Elevation

Answer 21

sternal end of clavicle moves down over articular disc

Question 22

Depression

Answer 22

sternal end of clavicle moves upwards over articular disc`
