Arteries Of The Arm

Front 1

axillary

Back 1

The subclavian artery passes beneath the clavicle, carrying blood to the arm. It becomes the axillary artery as it passes underneath the armpit.

Front 2

brachial

Back 2

That same vessel becomes known as the brachial artery as it enters the upper arm region.

Front 3

deltoid branch

Back 3

There is also a deltoid branch which, of course, supplies the deltoid muscle.

Front 4

humeral circumflex

Back 4

There is both a posterior and anterior humeral circumflex artery wrapped around the humerus.

Front 5

deep brachial

Back 5

Both the deep brachial and superficial brachial arteries are branches of the brachial artery. They supply blood to the arm.

Front 6

ulnar collateral

Back 6

There are both superior and inferior ulnar collateral arteries. They are branches of the brachial artery. They supply blood to the triceps and elbow.

Front 7

medial collateral

Back 7

This is a branch of the deep brachial artery and also supplies the triceps muscle and elbow joint.

Front 8

radial collateral

Back 8

Also a branch of the deep brachial artery, the radial collateral supplies the brachioradialis and brachialis muscles.

Front 9

ulnar recurrent

Back 9

There are both posterior and anterior branches of the ulnar recurrent artery. These supply the elbow joint region.

Front 10

radial recurrent

Back 10

A branch of the radial artery which supplies the brachioradialis, brachialis, and elbow region.

Front 11

interosseous

Back 11

There are several interosseous arteries, including the common interosseous, posterior interosseous, anterior interosseous, and recurrent interosseous. They distribute blood to various places within the arm. The word means "between bones."

Front 12

radial

Back 12

A fairly major artery off of the brachial artery. It supplies blood to the forearm, wrist, and hand.

Front 13

ulnar

Back 13

Also a fairly major artery off of the brachial artery, the ulnar artery distributes blood to the forearm, wrist, and hand.

Front 14

dorsal carpal branch of ulnar

Back 14

The name describes a specific branch of the ulnar artery. You already are familiar with dorsal and carpal so you should be able to ascertain where the blood supply goes.

Front 15

superficial palmar branch of ulnar

Back 15

The name describes a specific branch of the radial artery. You are already familiar with superficial and palmar so you should be able to ascertain where the blood supply goes.

Front 16

palmar arch

Back 16

There are both deep and superficial palmar arches that supply the hand and specifically the palm.

Front 17

metacarpals

Back 17

There are both palmar and dorsal metacarpal arteries. These supply the metacarpals.

Front 18

common palmar digitals

Back 18

This artery and the following two arteries all supply the digits (fingers).

Front 19

proper palmar digitals

Back 19

Supplies the fingers.

Front 20

dorsal digitals

Back 20

Supplies the fingers.

Front 21

princeps pollicis

Back 21

The principal artery of the thumb.

Front 22

radialis indicis

Back 22

The radial artery of the index finger. It specifically supplies the index finger (first digit).
