| The Axillary Artery
|
|
| Extents: |
| Lateral border of first rib as a continuation
of subclavian artery to the lower border of teres major where it continues
as brachial artery |
| |
| Parts: |
| Divided into three by pectoralis minor
muscle.
- Part 1 is proximal to the muscle.
- Part 2 is posterior to the muscle.
- Part 3 is distal to the muscle.

- Located medial to the axillary artery
- Receives tributaries corresponding to the branches
of the axillary artery; and the cephalic vein.
