Arteries of the Axilla

Branches of the Axillary Artery:

First:

• Superior to pectoralis minor muscle (up to first rib).

• The superior thoracic artery.

Second:

• Posterior (deep) to pectoralis minor muscle.

• The thoraco-acromial and lateral thoracic arteries.

Third:

• Inferior to pectoralis minor muscle.

• Subscapular, anterior and posterior circumflex humeral.

Note: the first part of the axillary artery gives off one branch. The second part gives off two branches and the third part gives off three branches. There is an alternate way of specifying the sub-parts of the axillary artery. The results are the same.

Parts of the Axillary Artery:

First:

• From lateral border of first rib to superior border of pectoralis minor.

Second:

• Deep to the pectoralis minor.

Third:

• Inferolateral to pectoralis minor.
