Apex of axilla

Cervico-axillary canal, passageway b/w the neck and axilla. Bounded by the first rib clavicle and superior edge of the scapula

1

Base of Axilla

Concave skin, subcutaneous tissue, and axillary fascia extending from the arm to the thoracic wall forming the axillary fossa(armpit)

2

Anterior wall of axilla

Pectoralis major and minor and the pectoral and clavipectoral fascia associated with them.
The anterior axillary fold is the most inferior part of the anterior wall

3

Posterior wall of axilla

Scapula and subscapularis on anterior suface
Teres major and latissimus doris on inferior surface
Posterior axillary fold is most inferior part that may be grasped

4

Medial wall of axilla

Thoracic wall and overlying serratus anterior

5

Lateral wall of axilla

Intertubercle sulcus of humerus

6

Axilla

Pyramidal space inferior to the glenohumeral joint and superior to the skin and axillary fascia at the junction of the arm and thorax
