1

What does the clavicle do?

acts as a strut to keep upper limp in lateral position, connects upper limp to axial skeleton

2

What is significant about the suprascapular notch?

superior transverse scapular ligament spans the notch to form a foramen for the passage of the suprascapular nerve

3

What does the glenoid cavity articulate with?

the humerus

4

What is found in the intertubercular groove (bicipital groove)?

the tendon of the long head of biceps brachii

5

Where is the radial groove? What does it contain?

it is located on the posterior shaft of the humerus, radial nerve and deep artery of the arm run through it

6

Sternoclavicular (SC) joint

synovial joint between the clavicle and the manubrium of the sternum

allows the clavicle and the manubrium to move anterior and posterior and allows for elevation and depression

7

Acromioclavicular AC joint

synovial joint between the clavicle and the acromion of the scapula

8

scapulothoracic (ST) joint

not a true anatomic joint

a functional joint, permitting movement of the scapula on the thoracic wall

9

What joints allow movement of the scapula?

SC joint

AC joint

ST joint

10

What are the movements of the scapula?

elevation, depression, retraction, protraction, upward rotation, downward rotation

11

Glenohumeral (GH) Joint

head of the humerus articulates with the glenoid cavity of the scapula, ball and socket joint with wide ROM

12

What are the movements of the glenohumeral joint?

Flexion/Extension

Abduction/Adduction

Medial Rotation/Lateral Rotation

13

What is meant by scapulohumeral rhythm?

for every 2 degrees of glenohumeral movement there is 1 degree of scapulothoracic movement

14

Elbow Joint

where the distal humerus articulates with the proximal radius and ulna

a hinge synovial joint

15

What movements occur at the elbow joint?

Flexion/Extension

16

Proximal and Distal Radioulnar Joints

synovial joints, ulna is stable and radius rotates

17

What movement occurs at the proximal and distal radioulnar joints?

Supination and Pronation

18

Wrist (radiocarpal) joint

synovial joint between the distal radius, articular discs and proximal carpals (scaphoid, lunate and triquetrum)

19

What movements occur at the wrist (radiocarpal) joint?

Extension/Flexion

Abduction/Adduction

20

What are the movements of the CMC joint of the pollex?

Extension/Flexion

Abduction/Adduction

Opposition/Reposition

21

Metacarpophalangeal (MCP) joints

synovial joints between the metacarpals and the proximal phalanges

22

What movements occur at the MCP joints?

Flexion/Extension

Abduction/Adduction

23

IP joints, what movements occur here?

hinge synovial joints between phalanges

Flexion/Extension

24

Function of flexor and extensor retinacula

keep tendons in place

25

What are the superficial veins of the UE?

dorsal venous network

cephalic vein

basilic vein

medial cubital vein

26

cephalic vein

arises from the lateral aspect of the dorsal venous network

travels along lateral aspect of forearm and arm and enters the deltopectoral triangle

27

Where does the cephalic vein drain into?

the axillary vein

28

Basilic vein

Arises from medial aspect of the dorsal venous network, courses along medial side of forearm and arm

joins brachial veins to form axillary vein

29

Median cubital vein

site of venipuncture

arises from the cephalic vein

30

What is a common variation of the median cubital vein?

median antebrachial vein which divides into median cephalic and median basilic veins
