Understanding the Axilla: Anatomy and Function

This certificate course delves into the anatomy and significance of the axilla, commonly known as the armpit. This area plays a crucial role in human physiology, housing sweat glands and contributing to body odor, which some studies suggest may function as pheromones. The course covers the structural boundaries of the axilla, including the posterior and anterior axillary folds, and the vital contents such as the axillary artery, vein, brachial plexus, and lymph nodes. Participants will explore the pathways through which structures exit the axilla, enhancing their understanding of this complex region’s role in the human body.
