Who Is Axillary Artery?

The axillary artery is the main artery of the upper extremity and originates as a continuation of the subclavian artery

at the lateral margin of the first rib. The artery has six primary branches and is divided into three parts based on its relation to the pectoralis minor muscle (Fig. 27-7).

Can you feel your axillary artery?

As a result of this attachment, the axillary artery is more easily palpated in the concavity of the axilla when the arm is adducted (close to the midline of the body) and the suspensory ligaments are relaxed, than when it is abducted (away from the midline of the body) and the suspensory ligaments are taut.

What are the 3 parts of the axillary artery?

It has three branches that are variable in their order: the subscapular trunk, the anterior humeral circumflex artery, and the posterior humeral circumflex artery. The subscapular trunk is typically the largest branch of the axillary artery.
