Where is the axillary located in the body?
Axillary Nodes. The axillary nodes are a group of lymph nodes located in the axillary (or armpit) region of the body. They perform the vital function of filtration and conduction of lymph from the upper limbs, pectoral region, and upper back.
The axillary nerve or the circumflex nerve is a nerve of the human body, that originates from the brachial plexus (upper trunk, posterior division, posterior cord) at the level of the axilla (armpit) and carries nerve fibers from C5 and C6.

- The axillary nerve or the circumflex nerve is a nerve of the human body, that originates from the brachial plexus (upper trunk, posterior division, posterior cord) at the level of the axilla (armpit) and carries nerve fibers from C5 and C6.
- It is involved in the external rotation of the shoulder joint. The other muscles composing the rotator cuff are the supraspinatus, infraspinatus, and subscapularis. It connects the scapula to the humerus, along with the teres major and infraspinatus muscles, which lie on either side and overlap the teres minor.
The armpit is also called the axilla. Blood and lymph vessels serving the arm travel through the armpit. There are more than 20 lymph nodes (small lumps of tissue that are part of the body's lymphatic system, which helps fight infection) in the armpit.
- For example, a cyst, infection or fatty growth may feel soft to the touch. However, fibroadenomas and cancerous tumors may feel hard and immobile. Some people may experience pain with an armpit lump. Lymph node infections may also cause painful lumps in the armpit.
- An armpit lump usually refers to the enlargement of at least one of the lymph nodes under your arm. Lymph nodes are small, oval-shaped glands that are located throughout the body. They play an important role in your body's immune system. The lump may feel small.
- In general, cancerous lumps tend to be more irregular in shape. They may also feel firm or solid, and might be fixed to the tissue in the breast. However, in a small percentage of women, a painful breast lump turns out to be cancer. Cysts, which are fluid-filled lumps, are common in the breast and are benign.
The subscapular axillary lymph nodes are located on the lower part of the armpit's posterior (rear) wall. The apical and pectoral nodes are located respectively on the upper and lower parts of the pectoralis minor, a thin, flat muscle of the chest.

- Enlarged lymph nodes.
- Sweating and chills.
- Weight loss.
- Fatigue (extreme tiredness)
- Swollen abdomen (belly)
- Feeling full after only a small amount of food.
- Chest pain or pressure.
- When cancer cells break away from a tumor, they can travel to other areas of the body through either the bloodstream or the lymph system. Cancer cells can travel through the bloodstream to reach distant organs. When cancer grows inside lymph nodes, it usually affects the lymph nodes near the tumor itself.
- axillary lymphadenopathy. A general term for clinically obviously enlargement of lymph nodes in the axillary region, which is a zone of lymphatic drainage from the arm and breast. Aetiology axillary lymphoadenopathy. •
