Where does axillary artery become brachial artery?

Axillary artery changes its name to the brachial artery at the level of the inferior border of the teres major muscle.

How do you expose axillary arteries?

The axillary artery, which lies superior and posterior to the vein, can be identified by palpation and then exposed using sharp dissection. The exposure can be improved by one or two self-retaining retractors and by gentle downward axillary vein traction. The pectoralis minor is retracted or divided.

What is the brachial artery?

The brachial artery is the extension of the axillary artery starting at the lower margin of the teres major muscle and is the major artery of the upper extremity. The brachial artery courses along the ventral surface of the arm and gives rise to multiple smaller branching arteries before reaching the cubital fossa.

What happens if the brachial artery is cut?

The Brachial artery runs along the inside of your arms. This artery is deep, but severing it will result in unconsciousness in as little as 15 seconds, and death in as little as 90 seconds.
