Multiple Choice

The posterior apex of the lung is at which vertebral level?

Explanation:
The lung apex projects into the neck and sits high behind the clavicle. On the posterior side, the highest point of the apex lines up with the seventh cervical vertebra. This location reflects how the pleural cupula extends into the thoracic inlet and how the spine’s cervical-to-thoracic transition places the posterior apex at that level, rather than at higher cervical levels or lower thoracic levels. So, the posterior apex corresponds to the seventh cervical vertebra.
