Description:[edit | edit source]

The axillary region (also known as the arm pit) is a pyramid-shaped area located between the shoulder girdle and thorax. It serves as a space for neurovascular and lymphatic structures to travel through to reach the upper extremity from the neck[1].

Structure/Borders:[edit | edit source]

  • Apex: (also known as cervicoaxillary margin, axillary inlet) region of entrance/exit of the axillary neurovascular bundle
    • 1st rib (lateral)
    • Scapula (superior portion and coracoid process)
    • Clavicle (posterior)[1][2]
  • Base:
    • Axillary skin
    • Fascia Axillaris
  • Anterior Wall:
  • Posterior Wall:
  • Medial Wall:
    • Ribs 1-4
    • Intercostal muscles of ribs 1-4
    • Serratus anterior
  • Lateral Wall:

The structure of the axilla is dependent upon the position of the upper extremity - an expansive region when the arm is elevated and minimized when adducted[2].

Contents:[edit | edit source]

  • Axillary artery
  • Axillary vein

  • Axillary lymph vessels and nodes
