Why is the axillary lymph nodes important?
Collectively, they drain the wall of the thorax, breast, arm, and upper abdominal wall above the umbilicus. The axillary lymph nodes are of particular clinical significance as they are often the first site of breast cancer metastasis.
What is the axilla in anatomy?
The axilla is an anatomical region under the shoulder joint where the arm connects to the shoulder. … The primary blood supply to the axilla is the axillary artery, which branches directly off of the subclavian artery.
What does axilla mean in medical terms?
axillary artery and veinMedical Definition of axilla : the cavity beneath the junction of the arm or anterior appendage and shoulder or shoulder girdle containing the axillary artery and vein, a part of the brachial plexus of nerves, many lymph nodes, and fat and areolar tissue especially : armpit.
How many levels of axillary lymph nodes are there?
There are three levels of axillary lymph nodes (the nodes in the underarm or “axilla” area): Level I is the bottom level, below the lower edge of the pectoralis minor muscle. Level II is lying underneath the pectoralis minor muscle. Level III is above the pectoralis minor muscle.
Are there muscles in your armpits?
Your armpits and the surrounding chest and arm area are made up of blood vessels, nerves, and muscles. Like other muscles in your body, you can strain armpit muscles by overdoing things, like lifting something heavy.

Are axillary lymph nodes normal?
The normal axillary lymph node should be oval and should have a smooth, well-defined margin (Fig 16). The cortex should be slightly hypoechoic and uniformly thin, measuring 3 mm or less. Nodes that meet this description have a very high negative predictive value for excluding metastases (9,18).
