Diaphragm function was graded by a senior radiology resident, as either “paralyzed” or “non-paralyzed,” based on appearance/shape of elevated hemidiaphragm on PA and lateral radiograph. The diaphragm position and shape for all patients were determined using measurements relating to skeletal structures and radius of curvature, respectively.

Conjunctiva This is the clear, thin membrane that lines the inside of the eyelids and the white of the eye. It helps to keep the eye moist and lubricated, and protect it from debris and infection. The conjunctiva also contains tiny blood vessels to supply oxygen and nutrients to the eye and eyelids. Cornea

Coincidentally, the vocal cords and glottis snap shut a fraction of second after the diaphragm spasms. This causes the air to hit the closed structure.
