Fig. 3From: Ultrasound imaging of the axillaCadaveric anatomy of the axillary region. Using an anterior approach (A) and lifting the skin and pectoralis major muscle (P Maj), the axillary fat tissue (yellow arrowheads) can be easily observed filling the anatomical space between the upper limb and the trunk. Using an inferior approach B and selectively removing the fat pad, a panoramic view of the axillary cavity can be acquired until its medial border—i.e., the serratus anterior (SA) muscle. Of note, the more superficial vein is the lateral thoracic vein (light blue arrowhead); instead, the axillary vein (AV) is located in the deep portion of the axilla (B). P Min: pectoralis minor muscle; LD: latissimus dorsi muscleBack to article page
