Parasternal lymph nodes

The parasternal lymph nodes (or sternal glands) are placed at the anterior ends of the intercostal spaces, by the side of the internal thoracic artery.

They derive afferents from the mamma; from the deeper structures of the anterior abdominal wall above the level of the umbilicus; from the upper surface of the liver through a small group of glands which lie behind the xiphoid process; and from the deeper parts of the anterior portion of the thoracic wall.
