Flashcards in Arteries, Veins, & Nerves of Limbs Deck (22):
1

What is the main arterial supply to the upper limb?

- the subclavian artery

2

What is the old traditional name for the brachiocephalic artery?

- the innominate artery

3

What is another name for the internal thoracic artery?

- the internal mammary

4

What are the 4 branches of the subclavian artery?

- the vertebral artery, internal thoracic artery, thyrocervical trunk, and costocervical trunk

5

At what point does the subclavian artery become the axillary artery?

- at the outer edge of the 1st rib

6

At what point does the axillary artery become the brachial artery?

- at the lower border of the teres major muscle (the lower border of the axilla)

7

What do we find in the cubital fossa going from lateral to medial?

- the tendon of the biceps brachii, the brachial artery, and the median nerve

8

At what point does the brachial artery become the radial and ulnar arteries?

- at the level of the neck of the radius

9

The ______ artery forms the deep palmar arch (coming from the ______ side of the hand), while the ______ artery forms the superficial palmar arch (coming from the ______ side).

- radial forms deep, comes from the posterior side
- ulnar forms superficial, comes from the anterior side

10

The palmar arches give rise to which arteries? How many of these arteries does each finger get?

- the digital arteries
- each finger gets 4 digital arteries

11

Which 5 major veins drain the upper limb?

- the subclavian, axillary, brachial, basilic, and cephalic veins
- (subclavian dumps into the brachiocephalic vein)

12

The basilic vein runs MEDIAL/LATERAL to the brachial vein.

- medial

13

Name the branches of the popliteal artery in the proper order.

- branches into the anterior tibial artery and then the fibular artery before continuing on as the posterior tibial artery

14

What are the two main bifurications for deep vein thromboses to occur?

- the bifurication of the common femoral into the superficial and deep branches
- the bifurication of the popliteal into the posterior tibial and fibular arteries

15

The _________ artery becomes the dorsalis pedis artery, while the ________ artery becomes the ________ arteries.

- anterior tibial becomes dorsalis pedis
- posterior tibial becomes (medial & lateral) plantar arteries

16

The dorsalis pedis branches off into the:

- the arcuate artery and then the deep plantar artery

17

Which arteries form the plantar arch?

- the deep plantar artery (from the dorsalis pedis) and the plantar arteries (from the posterior tibial)

18

The plantar arch gives rise to which arteries? These, in turn, give rise to which arteries?

- the plantar metatarsal arteries, which give rise to the plantar digital arteries

19

The arcuate artery gives rise to which arteries? These, in turn, give rise to which arteries?

- the dorsal metatarsal arteries, which give rise to the dorsal digital arteries

20

What are the three mechanisms that allow venous flow against gravity?

- musculo-venous pump, arterial inflow, and respiratory pressure changes

21

Which major vein runs anteriorly up the lower limb? What about posteriorly?

- anterior: great saphenous vein (joins the femoral vein right near the external iliac vein)
- posterior: lesser saphenous vein (joins the femoral vein around the knee area)

22

The junction where the great saphenous and the femoral veins join is known as:

- the saphenofemoral junction
