central tendon of the diaphragm
Other Terms: Central tendon of diaphragm, Centrum tendineum, Centrum tendineum diaphragmatis, Centre phrénique
The central tendon is the large tendinous region forming the top of the dome-shaped diaphragm. This strong aponeurosis appears as three leafs radiating from the center. Projecting forward is a triangular leaf and to each side are rounded leaves that arch posteriorly. Near the center strong collagenous bands cross diagonally as they wrap around the openings for the inferior vena cava and esophagus. Superiorly, the strong central tendon is blended with the fibrous pericardial sac, which it helps anchor in place.
