기능

The primary muscle of respiration. Contraction flattens the dome-shaped muscle, increasing thoracic volume and creating negative pressure to draw air into the lungs during inspiration.

임상적 의의

Diaphragmatic hernias allow abdominal organs to enter the thoracic cavity. Phrenic nerve paralysis causes diaphragmatic elevation. Hiccups result from involuntary diaphragmatic spasms.
