apex lung (anatomy)
Last reviewed 01/2018
The apex of each lung is its most superior point where both costal and mediastinal surfaces merge. It is sited 2-3cm superior to the medial third of the clavicle where it projects through the superior thoracic inlet.
Superior to the apex are the visceral and parietal layers of pleura deep to the suprapleural membrane. Lung parenchyma is relatively exposed at each apex and particularly, it is exposed to penetrating injuries of the neck.
