Kin chapter 9 Shoulder girdle

Question 1

Shoulder complex

Answer 1

scapula, clavicle, sternum, humerus, and rib cage, sternoclavicular joint, acromioclavicular joint, glenohumeral joint, and scapulothoracic articulation

Question 2

shoulder girdle

Answer 2

basically scapula and clavical

Question 3

shoulder joint

Answer 3

scapula and humerus (glenohumeral joint)

Question 4

superior angle

Answer 4

superior medial aspect, providing attachment for the levator scapula

Question 5

inferior angle

Answer 5

moste inferior point and where vertebral and axillary border meet. This point determines scapular rotation.

Question 6

vertebral border

Answer 6

between superior and inferior angles medially and attachment of the rhomboid and serratus anterior muscles

Question 7

axillary border

Answer 7

the lateral side between glenoid fossa and inferior angle

Question 8

spine of the scapula

Answer 8

projection on posterior surface, running from medial border laterally to acromion process. it provides attachment for the middle and lower trapezius muscles.

Question 9

coracoid process

Answer 9

projection on anterior surface providing attachment for the pectoralis minor muscle

Question 10

acromion process

Answer 10

broad flat area on superior lateral aspect, providing attachment for the upper trapezius muscle.

Question 11

glenoid fossa

Answer 11

slightly concave surface that articulates with humerus on superior lateral side above the axillary border and below the acromion process.

Question 12

clavicle

Answer 12

S shaped bone connects axial skeleton at the steroclavicular joint.

Question 13

sternal end of clavicle

Answer 13

attaches medially to sternum

Question 14

acomial end of clavicle

Answer 14

attaches laterally to scapula and provides attachment for the upper trap muscle

Question 15

body of clavicle

Answer 15

ara between two ends

Question 16

sternum

Answer 16

flat bone located in medline of the anterior thorax

Question 17

manubruim

Answer 17

superior end, providing attachment for the clavicle and the first rib

Question 18

body of sternum

Answer 18

the middle two thirds of the sternum, provide attachments for the remaining ribs

Question 19

xiphoid processq

Answer 19

meaning sword shaped, the inferior tip.

Question 20

sternoclavicular joint

Answer 20

synovial joint that is the shoulder girdles only attachment to the trunk. motion include elevation/depression, protraction/retraction, rotation. occurs in three planes, hence this joint has 3 degrees of freedom. clavicle moves while sternum remains still.

Question 21

how many degrees of freedom does the sternoclavicular joint have?

Answer 21

3.

Question 22

What are the 3 major ligaments around the sternoclavicular joint?

Answer 22

sternoclavicular ligament
costoclavicular ligament
interclavicular ligament

Question 23

sternoclavicular ligament

Answer 23

clavicle<>sternum
anterior and posterior sternoclavicular ligaments
posterior limits anterior movement of the clavicles medial end
anterior limits posterior movement of the clavicles medail end.

Question 24

costoclavicular ligament

Answer 24

short flat, rhomboid shaped liagament
clavicles inferior surface<>superior surface costal cartilage of first rib.
limit amount of clavicular elevation.

Question 25

interclavicular ligament

Answer 25

top of manubrium<>superior sternal ends of clavicle

limit clavicular depression
