Underarm - Definition

Definition


The underarm is the anatomical zone in the form of a pyramid that describes the hollow situated under the shoulder between the internal side of the arm and the side of the torso. It's a zone which contains hair and is extremely vascular and sensitive. This region, called the axillary region, also contains a large quantity of sweat glands, responsible for the production of sweat, and lymphatic ganglions, which play a role in the immune system by draining the lymph that comes from the arm. Doctors may examine this area if a patient has immunity problems, an infectious disease, or breast cancer.
