The axillary cavity, also known as the armpit or underarm, is a space located under the shoulder joint, between the upper part of the arm and the side of the chest. It houses various structures including lymph nodes, blood vessels, and nerves. This area is important in medicine and health due to its role in lymphatic drainage and close proximity to important vascular and nervous structures.
