2. thoracodorsal nerve
3. lower subscapular nerve

Front 7

Brachial plexus

Back 7

innervates pectoral girdle and upper limb. C5-C8, T1
The 5 nerves from this plexus converge into 3 trunks, superior middle and inferior.

Front 8

Roots of brachial plexus

Back 8

5 nerves; C5, 6, 7, 8 and T1
Collectively form 3 roots

Front 9

Trunks of brachial plexus

Back 9

Upper C5 and C6
Middle C7
Lower C8 and T1

Divide into 6 Divisions, anteriorly and posteriorly

Front 10

Divisions of Brachial Plexus

Back 10

Come off of trunks (upper, middle, and lower). Two divisions per trunk, one anterior and one posterior. Converge to give Cords

Front 11

Cords of Brachial Plexus

Back 11

lateral, posterior, medial

Front 12

lateral cord

Back 12

convergance of anterior divisions of upper(C5-6) and middle(C7) trunks of brachial plexus.

Front 13

posterior cord

Back 13

convergance of posterior divisions of all three trunks of the brachial plexus

Front 14

medial cord

Back 14

a continuance of the lower trunk (like its anterior division, because its posterior goes to the posterior cord)

Front 16

axillary artery

Back 16

offspring of the subclavian artery. upon crossing the teres major at the armpit, becomes the brachial artery.

Front 17

brachial artery

Back 17

supplies the brachial muscles (surprise); offspring of the axillary arery. gives rise to the deep brachial artery, and then continues down the spiral groove of the humerus.

Front 18

deep brachial artery

Back 18

a branch of the brachial artery; supplies blood to the posterior upper arm.

Front 19

ulnar artery

Back 19

a branch of the brachial artery that splits at the elbow joint (cubital fossa). the other branch is the radial

Front 20

radial artery

Back 20

a branch of the brachial artery that splits at the cubital fossa. the other branch is the ulnar

Front 21

superficial palmar arch

Back 21

the fate of the ulnar artery; a loop in the palm of the hand (facing anteriorly in anatomical position). anastomoses with the deep palmar arch.

Front 22

deep palmar arch

Back 22

the fate of the radial artery; anastomoses with the superficial palmer arch; located in the back of the hand (dorsal in anatomical position)

Front 23

Deep veins of the arm

Back 23

correspond to the arteries they run with

Front 24

superficial veins of the arm

Back 24

cephalic, basilic, median cubital

Front 25

Subclavian artery

Back 25

underneath the clavicle, offspring of the brachiocephalic trunk. upon coming out from hiding under the clavicle, becomes the axillary artery in the armpit.
