Axilla (Armpit) PART-1

  1. The axilla or armpit is a fat-filled pyramid-shaped space, between the upper part of the arm and the side of the chest wall.

  2. It contains the brachial plexus, axillary vessels, and lymph nodes.

  3. It also acts as a funnel shaped tunnel for neurovascular structures to pass from the root of the neck to the upper limb and vice versa.

  4. Groups of lymph nodes within it drain the upper limb and the breast.

  5. The study of axilla is clinically important because axillary lymph nodes are often enlarged and hence routinely palpated during physical examination of the patient.

  6. Abscess in this region is also common.
