29. Arteries, Veins & Lymphatics Of The Upper Limb

Front 1

basic structure of arteries of upper limb

Back 1

subclavian a

axillary a

brachial a

radial & ulnar a

Front 2

shoulder and upper arm supplied by

Back 2

subclavian a

Front 3

it runs behind the

Back 3

clavicle

Front 4

and becomes the

Back 4

axillary a

Front 5

which extends to the

Back 5

pectoralis major muscle

Front 6

and there it becomes the

Back 6

brachial a

Front 7

axillary artery

Back 7

highest thoracic artery

thoracoacromial artery

lateral thoracic artery

subscapular artery

- circumflex scapular artery

- thoracodorsal artery

post circumflex a of the humerus - large branch, travels with axillary nerve

anterior circumflex a of humerus - small branch

Front 8

brachial artery: runs with the

Back 8

median nerve in the median groove of the biceps muscle

Front 9

at the elbow it divides into the

Back 9

radial a and the ulnar a

Front 10

radial artery: runs beneath the

Back 10

brachioradialis muscle (guideline structure) to the thumb side of the hand

Front 11

it then passes through the

Back 11

radial foveola (anatomists snuff box)

Front 12

onto the

Back 12

dorsum of the hand, around 1st metacarpal

Front 13

branches of radial artery

Back 13

1. radial recurrent artery

2. dorsal metacarpal artery

3. principal carpal artery of the thumb

Front 14

1. radial recurrent artery

Back 14

gives small branches to the carpus (wrist) and the superficial palmar arch

Front 15

2. dorsal metacarpal artery

Back 15

goes to the dorsal aspect of the thumb and index finger

Front 16

3. principal carpal artery of the thumb

Back 16

to the palmar aspect of the thumb and index finger

Front 17

ulnar artery: runs beneath the

Back 17

flexor carpi ulnaris, to little finger side of the wrist and ends as the superficial palmar arch

Front 18

branches of the ulnar artery

Back 18

1. recurrent ulnar artery

2. common interosseus artery - post/ant

recurrent interosseus artery

Front 19

posterior interosseus artery

Back 19

runs towards the hand with the deep branch of the radial artery

Front 20

anterior interosseus artery

Back 20

runs along the palmar aspect of the interosseus membrane towards the hand

Front 21

branches of recurrent interosseus artery

Back 21

dorsal and palmar carpal branches

deep palmar branch

Front 22

arteries of the hand:

Back 22

mainly in the muscles of the palm where the metacarpal and finger arteries arise from 2 arterial palmar arches

a weaker dorsal carpal branch gives of arteries to the back of the hand (a branch of the radial a)

Front 23

superficial palmar arch

Back 23

mainly supplied by the ulnar artery

the little finger gets a branch directly from the palmar arch

Front 24

deep palmar arch

Back 24

it's near the base of the metacarpals

it's supplied mainly by the radial artery, but also a deep palmar branch of the ulnar artery

Front 25

veins of upper limb

Back 25

1. Basilic vein

2. Cephalic vein

3. Median cubital veins

other deep veins - ulnar & radial veins

Front 26

1. Basilic vein

Back 26

runs along ulnar (lil finger) side of the forearm towards the brachial vein

Front 27

2. Cephalic vein

Back 27

runs along the radial (thumb) side of the arm and drains into the axillary vein

Front 28

3. Median cubital veins

Back 28

lie in the cubital fossa and run between the basilic and cephalic veins

used for intravenous injections

Front 29

lymphatics of upper limb

Back 29

1. Axillary lymph nodes

2. Superficial and deep cubital lymph nodes

Front 30

1. Axillary lymph nodes

Back 30

drains arm and trunk

Front 31

2. Superficial and deep cubital lymph nodes

Back 31

lie at the elbow

receive subcutaneous lymphatics (even from the hand)

some lymphatics from the thumb bypass them and drain straight into the axillary lymph nodes
