What does the axillary artery become?

What is the lateral thoracic artery?
The lateral thoracic artery is a highly variable vessel in terms of origin and distribution. Occasionally, the lateral thoracic artery can be absent. When that occurs, this artery is replaced by branches of the intercostal arteries. The lateral thoracic artery can originate from the thoracoacromial artery or subscapular artery.
Is the lateral thoracic vein visible from the front?
