The video tutorial explains the axillary artery, its origin from the subclavian artery, and its transition to the brachial artery. It details the three parts of the axillary artery, each with specific branches, and their relation to the brachial plexus. The video also covers the muscles supplied by these branches and the transition of the axillary artery into the brachial artery, highlighting the profunda brachii artery's role in supplying the triceps brachii.
