Uberon Homology note : In mammals, the diaphragm muscle divides the thoracoabdominal cavity into thorax and abdomen. In most mammals, the diaphragm is a flat sheet with muscle fibers radiating outward from a central tendon, and the diaphragm's apposition to the cranial surface of the liver gives it a dome-shape. Muscle fiber contraction reduces the curvature of the dome, thereby expanding the thoracic cavity and aspirating air into the lungs.[well established][VHOG];
