Where are the subclavicular nodes located?

The subclavicular nodes, also known as supraclavicular lymph nodes, are located just above the clavicle. This positioning is significant because the subclavicular nodes serve as important collectors for lymphatic drainage from various regions of the body, including the head, neck, and upper limbs. Their location makes them pivotal in assessing the spread of infections or malignancies, particularly in relation to the lungs and breast tissues. Understanding the anatomy and function of these nodes can help in identifying potential health issues during physical examinations and in planning treatment strategies.
