Study Notes
Axillary Structures
- The axilla contains many important structures, including:
- Brachial plexus
- Axillary artery and vein
- Axillary lymph nodes
- Long thoracic nerve
- Intercostobrachial nerve
Clinical Importance of Axilla
- The study of axilla is clinically important because it:
- Helps diagnose and treat breast cancer, as axillary lymph nodes are often the first site of metastasis
- Allows for evaluation of lymph node status, which is crucial in cancer staging
- Facilitates identification of axillary vein thrombosis, a complication of central venous catheter placement
Drainage of Axillary Lymph Nodes
- Groups of lymph nodes within the axilla drain:
- The breast, chest wall, and upper limb
- The arm, forearm, and hand, through the cephalic, basilic, and brachial veins
- The skin and superficial tissues of the arm and forearm
