The auxiliary region of the body, commonly referred to as the axillary region, is located under the arm, where the upper limb meets the torso. It contains important structures such as lymph nodes, blood vessels, and nerves, including the brachial plexus. The axilla plays a crucial role in the function and mobility of the shoulder and upper arm, as well as in the immune response due to its lymphatic tissues.
