Main arteries of the upper limb

The video tutorial explores the anatomy of the main arteries in the upper limb, starting from the shoulder and scapular region, moving through the arm and forearm, and ending with the wrist and hand. It covers the subclavian, axillary, brachial, radial, and ulnar arteries, as well as the anastomotic networks that ensure continuous blood flow. Clinical notes highlight the importance of the brachial and radial arteries in medical assessments. The tutorial aims to provide a comprehensive understanding of the arterial network in the upper limb.
