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
- Base:
- Axillary skin
- Fascia Axillaris
- Anterior Wall:
- Pectoralis major
- Pectoralis minor
- Posterior Wall:
- Subscapularis
- Latissimus dorsi
- Teres major
- 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].
