CVS DR2 - Vasculature of Limbs & lymphatic drainage

Question 1

What artery supplies each upper limb?

Answer 1

Subclavian artery

Question 2

What is the difference between the right subclavian artery & the left subclavian artery?

Answer 2

Left subclavian arises from aortic arch

Right subclavian artery arises from the bracheocephalic artery, which arises from the aortic arch

Question 3

What artery is a continuation of the subclavian artery?

Answer 3

Axillary artery

Question 4

Where does the subclavian artery finish?

Answer 4

Lateral border of the first rib

Behind (deep to) the clavicle

Question 5

What artery is a continuation of the axillary artery?

Answer 5

Brachial artery

Question 6

When does the axillary artery finish?

Answer 6

Becomes brachial artery in the same horizontal line as the 4th rib

Question 7

What side of the arm does the axillary/brachial artery run down?

Answer 7

Medial (inner) side of arm

Question 8

What does the brachial artery turn into?

Answer 8

Bifurcates in to the radial and ulnar arteries

Question 9

When do the radial and ulnar arteries begin?

Answer 9

Antecubital fossa

• This is the soft bit on the inside of your elbow

Question 10

Which is more superficial, the radial or ulnar arteries?

Answer 10

Radial artery is more superficial

Question 11

What pulses do we look for on the upper limb?

Answer 11

Brachial pulse

Radial pulse

Question 12

Describe where the Radial pulse is found

Answer 12

Proximal to wrist joint, on the radial side of the flexor surface of the wrist & the lateral to the tendon of the flexor carpi radialis

Question 13

Describe where the brachial pulse is found

Answer 13

Antecubital fossa, medial to the biceps tendon

Question 14

What arteries arise from the bottom of the aorta?

Answer 14

Left & right common iliac

Question 15

What arteries arise from teh common iliac arteries?

Answer 15

Internal & external iliac

Question 16

What artery arises from the external iliac artery?

Answer 16

Common femoral

this splits quickly and is quite short

Question 17

What arteries arise from the common femoral?

Answer 17

Deep & superficial femoral

Question 18

The superficial femoral artery eventually becomes the ________

Answer 18

Popliteal artery

Question 19

What arteries branch off the popliteal artery?

Answer 19

Anterior & posterior tibial

Question 20

What artery gives rise to the Dorsalis pedis artery?

Answer 20

Anterior tibial

Question 21

Describe the course of the Superficial femoral artery down the leg

Answer 21

Runs down the inner thigh before bending and running to the back of the femur

Once it arrives at the femur, it becomes the popliteal artery

Question 22

What group of arteries split off the popliteal artery in the Popliteal fossa (back of the knee)?

Answer 22

Genicular arteries

Question 23

When does the popliteal artery split into the anterior & posterior tibial arteries?

Answer 23

Just below the Popliteal fossa (back of knee)

Question 24

Describe the course of the posterior tibial artery

Answer 24

Runs posterior to the tibia funnily enough

Continues down and enters the sole of the foot inferior to the medial malleolus (malleolus = bony projection on the side of your ankles)

Ie the left PT aa will enter the sole of the foot inferior to the medial (right) malleolus of the left foot

Question 25

What pulses can be palpated on the lower limbs?

Answer 25

Femoral

Popliteal

Posterior tibial

Dorsalis pedis

Question 26

Describe where the femoral pulse is located

Answer 26

Inferior to inguinal ligament, half way between the anterior superior iliac spine and the symphysis pubis (mid inguinal point)

Question 27

Describe where the popliteal pulse is located

Answer 27

Behind the knee joint (popliteal fossa)

Question 28

Describe where the Posterior tibial pulse is located

Answer 28

Behind and about 2cm below the medial malleolus

Question 29

Describe where the dorsalis pedis pulse is located

Answer 29

On the dorsum of the foot, lateral to tendon of the extensor hallucis longus (the tendon to the big toe)

In groove between 1st and 2nd metatarsals
