Left phrenic nerve palsy (right image side) in fluoroscopy: forced inspiration with the closed mouth leads to paradox elevation of the paralytic left diaphragm while the healthy right side moves down. Pain arising from structures supplied by the phrenic nerve is often "referred" to other somatic regions served by spinal nerves C3-C5.
Structure of diaphragm shown using a 3D medical animation still shot. The thoracic diaphragm, or simply the diaphragm (/ ˈ d aɪ ə f r æ m /; [1] Ancient Greek: διάφραγμα, romanized: diáphragma, lit.

The diaphragm typically appears as two separate, curved outlines (hemidiaphragms) on a chest X-ray due to the heart and mediastinum obscuring its central portion. When air accumulates in the mediastinum or peritoneal cavity, it outlines the diaphragm, making its central portion visible and creating the appearance of a continuous line. [4]
The free edge of a ruptured diaphragm may curl and become perpendicular to the chest wall, a sign known as a dangling diaphragm. A herniated organ may constrict at the location of a rupture, a sign known as the collar sign. If the liver herniates through a rupture on the right side, it may produce two signs known as the hump and band signs.
Diaphragmatic paradox or paradoxical diaphragm phenomenon is an abnormal medical sign observed during respiration, in which the diaphragm moves opposite to the normal directions of its movements. The diaphragm normally moves downwards during inspiration and upwards during expiration. But in diaphragmatic paradox, it moves upwards during ...
The number of side effects, complications, and possible permanent effects of pregnancy would fill a book, yet people still try to pretend it’s a perfectly normal and harmless process and women ...
Litten's sign, also known as the diaphragm phenomenon, [1] is a paralyzed hemidiaphragm, the portion of the diaphragm in contact with the parietal pleura during respiration in the base of the pleural cavity.
