Flashcards in UL Deck (35):
1

What makes up the pectoral girdle?

scapula and clavicle

2

What is the only joint to connect the upper limb to axial skeleton?

sternoclavicular joint

3

Why is there only one joint between the UL and axial skeleton?

want maximum range of motion

4

Does the scapula articulate with the axial skeleton?

no

5

Is the clavicle part of the axial skeleton?

no

6

What is the ball and socket join of the shoulder?

glenohumeral joint

7

What type of joint is the elbow?

hinge joint w/ 3 bones

8

What are the three main areas of transition in the UL?

axilla
cubital fossa
carpal tunnel

9

What must the vasculature of the UL cross?

must go up and over the 1st rib

10

Where would you check to see if C6 was damaged?

thumb

11

Where would you check to see if C7 was damaged?

index finger

12

Where would you check to see if C8 was damaged?

pinky finger

13

Where would you check to see if T1 was damaged?

medial forearm

14

Where would you check to see if T2 was damaged?

axilla

15

What are the superficial veins of the UL?

cephalic v.
basilic v.
median cubital v.
dorsal venous arch.

16

What does the cephalic vein drain?

dorsal posterior/later UL

17

Where does the cephalic vein run?

in deltopectoral groove, pierces deep fascia and goes through clavicular-pectoral triangle

18

What does the basilic vein drain?

anterior/medial UL

19

What is the cephalic vein a tributary to?

axillary v.

20

What is the basilic vein a tributary to?

brachial v.

21

Where is the median cubital vein?

connects the cephalic and basilic veins in the cubital fossa region

22

What vein is most used for IVs?

median cubital v.

23

Why is the dorsal venous arch of the hand important?

it creates medial/later and anterior/posterior anastomoses of all supply to UL

24

What is the deep fascia of the arm?

brachial fascia

25

How is the brachial fascia connected to the humerus?

2 septa, medial and lateral

26

Why is the deep fascia of the arm important?

Divides arm into anterior and posterior compartments

advantage: infection borders
disadvantage: increased pressure can affect circulation

27

Is the anterior compartment smaller or larger than the posterior compartment in the proximal UL?

smaller

28

Is the anterior compartment smaller or larger than the posterior compartment in the middle and distal UL?

neither, the compartments are about the same size

29

What muscles are contained in the anterior compartment?

biceps brachii m.
coracobrachialis m.
brachialis m.

30

What nerves and vessels are contained in the anterior compartment?

brachial vessels

5 brachial plexus nerves

31

What are the motor nerves contained in the anterior compartment?

musculocutaneous n.
median n.
ulnar n.

32

What are the cutaneous nerves contained in the anterior compartment?

medial brachial n.
median antibrachial cutaneous n.

33

What muscle(s) is contained in the posterior compartment?

triceps brachii m.

3 heads: long, lateral, medial

34

What nerve is contained in the posterior compartment?

radial n.

35

What major vessel is contained in the posterior compartment?

deep brachial a.
