The organization attachment towards the lumbar vertebrae makes sure that the diaphragm remains securely set up, making it possible for it to perform its respiratory and various functions proficiently. This posterior anchorage complements the anterior and lateral attachments, forming a robust assist system to the diaphragm.

In the course of swallowing, the crural diaphragm quickly relaxes to permit food passage, indicating a useful divergence from respiratory activity. This rest allows the esophagus to increase and accommodate food, highlighting the diaphragm’s position in digestion.
The commonest harm to the phrenic nerve is by bronchial most cancers, which ordinarily only affects 1 side in the diaphragm. Other triggers incorporate Guillain–Barré syndrome and systemic lupus erythematosus.[19]
