Boundaries and Branches of the Axillary Artery

The video tutorial provides an in-depth look at the axillary artery, detailing its start and end points, divisions, and branches. It begins with the transition from the subclavian artery and ends as the brachial artery. The axillary artery is divided into three parts, each with specific branches: the superior thoracic artery from the first part, the thoracoacromial and lateral thoracic arteries from the second, and the subscapular and circumflex humeral arteries from the third. The tutorial also highlights the anatomical landmarks and associated nerves.

Where does the axillary artery begin?

• At the clavicle

• At the coracoid process

• At the lower border of teres major

• At the lateral edge of the first rib

• Into five parts

• Into four parts

• Into three parts

• Into two parts
