Document Summary

Axillary boundaries: axilla: armpit region, pyramidal space, borders: Anterior wall: between 1st rib, clavicle, and superior edge of subscapularis skin and fascia of armpit. Pectoralis major/minor, clavipectoral fascia: anterior axillary fold: Pectoralis major anterior surface of scapula, subscapularis, teres major, Posterior wall: and latissimus dorsi: posterior axillary fold: Axillary contents: axillary sheath contains, axillary artery, axillary vein, cords of brachial plexus. Lateral: axillary lymph nodes: sit just outside of axillary sheath. Lymph drains through series of small lymphatic vessels, which are relatively superficial: lymphatic vessels ultimately drain into lymph nodes, cubital lymph nodes, axillary lymph nodes: : located anterior to medial epicondyle where all lymph, excluding cubital lymph nodes, drains into: made up of 5 sets of lymph nodes, pyramid of the axilla base of pyramid base of pyramid. Apical lymph nodes: base of pyramid middle of pyramid apex of pyramid: all lymph will eventually flow back into the blood stream, through venous system.
