Where does the axillary artery begin and terminate?

The axillary artery begins at the lateral border of the first rib, where it is a continuation of the subclavian artery. It supplies blood to the upper limb and is an important vessel in the circulatory system of the arm. This artery then terminates at the inferior border of the teres major muscle, where it changes its name to the brachial artery.

This specific anatomical pathway is crucial for understanding vascular supply in the upper limb, particularly during medical procedures or in the context of trauma, as knowing the precise locations can significantly impact surgical approaches or interventions. The understanding of these landmarks aids in proper identification and management of vascular issues.

The other options suggest different anatomical landmarks that do not accurately describe the correct beginning and termination points of the axillary artery, which are essential in ensuring a robust understanding of human anatomy, particularly in medical and clinical settings.
