Anatomy: Blood Vessels and Lymphatics of the Upper Limb

Question 1

How does the brachial artery terminate?

Answer 1

Bifuricates into the radial and ulnar arteries as it moves through the cubital fossa

Question 2

What does the ulnar artery supply?

Answer 2

The anteromedial aspect of the forearm, gives rise to the anterior and posterior interosseous arteries

Question 3

Where are the deep lymphatic vessels of the upper limb located?

Answer 3

Follow the major deep veins (i.e. radial, ulnar and brachial veins)

Question 4

Which apical lymph node receives much lymph from the breast?

Answer 4

Pectoral node

Question 5

When does the subclavian artery become the axillary artery?

Answer 5

At the lateral border of the first rib

Question 6

Where do the cubital lymph nodes drain into?

Answer 6

Continue up the arm, terminating in the lateral axillary lymph nodes

Question 7

What is the profunda brachii?

Answer 7

Deep artery given off by the brachial artery which travels in the radial groove of the humerus and supplies structures in the posterior aspect of the upper arm (e.g. triceps brachii)

Question 8

Where do the superficial lymphatic vessels of the upper limb initially arise from?

Answer 8

Lymphatic plexuses in the skin of the hand

Question 9

Which apical lymph node receives lymph from the scapular region?

Answer 9

Subscapular node

Question 10

Name the deep veins of the upper limb

Answer 10

Ulnar veins, radial veins, brachial veins, axillary vein

Question 11

Where are the majority of the upper extremity lymph nodes located?

Answer 11

In the axilla

Question 12

Where does the brachial vein become the axillary vein?

Answer 12

At the lower border of teres major

Question 13

What does the radial artery supply?

Answer 13

The posterolateral aspect of the forearm

Question 14

Where do the central lymph nodes drain into?

Answer 14

Apical nodes

Question 15

Where do the basal lymph nodes drain into?

Answer 15

Central nodes

Question 16

What is the median cubital vein?

Answer 16

Connection between the cephalic and basilic veins within the cubital fossa

Question 17

Where does the axillary artery become the brachial artery?

Answer 17

At the lower border of the teres major muscle

Question 18

Where do lymph vessels shadowing the basilic vein drain into?

Answer 18

Cubital lymph nodes

Question 19

Where are the basal pectoral lymph nodes located?

Answer 19

Along the lateral border of pectoralis minor

Question 20

What are the proper digital arteries?

Answer 20

As the common digital arteries travel from the palm toward the fingers, they split near the finger web spaces to become the proper digital arteries

Question 21

How many neurovascular bundles supply each finger?

Answer 21

4

Question 22

Where does the cephalic vein drain into?

Answer 22

Axillary vein

Question 23

Where do lymph vessels shadowing the cephalic vein drain into?

Answer 23

Generally cross the proximal part of the arm and shoulder to enter the apical axillary lymph nodes, some enter the deltopectoral lymph nodes

Question 24

The radial and ulnar arteries anastomose in the hand by forming which structures?

Answer 24

The superficial palmar arch, and the deep palmar arch

Question 25

The arterial supply to the upper limb begins as which artery?

Answer 25

Subclavian artery

Question 26

Where can pulsations of the subclavian artery be palpated?

Answer 26

Where the artery crosses the first rib

Question 27

Where does the basilic vein arise from?

Answer 27

Dorsal venous network

Question 28

Where does the cephalic vein arise from?

Answer 28

Dorsal venous network

Question 29

Where do the deep lymphatic vessels of the upper limb terminate?

Answer 29

Humeral axillary lymph nodes

Question 30

Where does the axillary vein become the subclavian vein?

Answer 30

At the lateral border of rib 1

Question 31

Where are the apical lymph nodes located?

Answer 31

In the apex of the axilla, close to the axillary vein and 1st part of the axillary artery

Question 32

What are the common digital arteries?

Answer 32

Branches which emerge from the palmar arches to supply the fingers

Question 33

Where does the basilic vein drain into?

Answer 33

Combines with the brachial veins (deep veins) to form the axillary vein

Question 34

Describe the structure of the deep venous system of the upper limb

Answer 34

Formed by paired veins, which accompany and lie either side of an artery

Question 35

Where do the apical lymph nodes drain into?

Answer 35

Towards the right lymphatic duct/thoracic duct
