Uberon definition : the three-lobed cloverleaf-shaped aponeurosis situated at the center of the diaphragm;
the central tendon is fused with the fibrous pericardium that provides attachment
for the muscle fibers;
Uberon synonym : central tendon; centrum tendineum;
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
