Branches
The axillary artery has several smaller branches. The branches can be remembered, in order, when traveling from the heart, with the mnemonic "Screw The Lawyers Save A Patient", "Summertime: The Lakers Schedule Another Parade", or "She Tastes Like Sweet Apple Pie." The origin of these branches is highly variable (e.g. the posterior and anterior circumflex arteries often have a common trunk). An arterial branch is named for its course, not its origin.
- First part (1 branch)
- Superior thoracic artery (Supreme thoracic artery)
- Second part (2 branches)
- Thoraco-acromial artery
- Lateral thoracic artery. If the lateral thoracic artery is not branching from the axillary artery, will most likely branch from the following (in order of likelihood): (1) thoracoacrominal, (2) third part of axillary artery, (3) suprascapular artery, (4) subscapular artery
- Third part (3 branches)
- Subscapular artery
- Anterior humeral circumflex artery
- Posterior humeral circumflex artery
Continues as the brachial artery past the inferior border of the teres major.
