The subclavian fossa is the depression between the collarbone and the first rib on the front surface of the chest. It is part of the deltoid-pectoral triangle, which is formed between the deltoid muscle, collarbone and sternum.
The subclavian fossa is important for human anatomy and physiology. This fossa contains the subclavian vessels, nerves and lymph nodes, which provide blood supply and innervation to the upper body. Lymphatic vessels are also located here, which drain lymph from tissues located in the neck, head and upper back.
In addition, the subclavian fossa is an important site for surgical procedures on the upper body, such as breast, thyroid, and vascular and nerve operations.
Overall, the subclavian fossa plays an important role in the anatomy and physiology of the upper body and is an important area for surgical procedures.
