- Answer: A great deal of anatomy lies underneath the ribs. A rib fragment can puncture any of these structures, causing further problems. In the case of a tension pneumothorax, a piece of the fractured rib punctures underlying lung tissue, causing air to escape into the pleural cavity and placing pressure on the lung, causing it to collapse. If a significant portion (30% to 40%) of the lung collapses, it begins to compress the great vessels, impeding blood return to the heart, which causes JVD, as well as pressing against the trachea, which causes tracheal deviation.
- Answer: The spinal nerves originating in the cervical regions C6 and C7 provide nervous stimulation to the intercostal muscles, providing the ability for the thoracic cage to elevate during inspiration.
