| Anatomical terminology | |
The central tendon of the diaphragm is a thin but strong aponeurosis situated slightly anterior to the vault formed by the muscle, resulting in longer posterior muscle fibers.
It is inferior to the fibrous pericardium, which fuses with the central tendon of the diaphragm via the pericardiacophrenic ligament.
The caval opening (at the level of the T8 vertebra) passes through the central tendon. This transmits the inferior vena cava[1] and right phrenic nerve.
