What pierces the central tendon of the diaphragm?
The vena caval foramen passes through the tendon at the level of the T8 vertebra, posterior to the 6th costal cartilage and to the right of the midline 1. The inferior vena cava and right phrenic nerve pass through this opening.
What 3 holes are in the diaphragm?
The diaphragm has three “holes”, one each for the aorta, the esophagus and the vena cava.
What are the 3 holes openings in the diaphragm for?
Anatomically, you can define hiatus as an opening, slit, or gap that allows structures to pass. These openings in the diaphragm allow the inferior vena cava, esophagus, vagus nerves, descending aorta, and other structures to pass through.
What forms the central tendon of the diaphragm?
The muscle and its associated connective tissue and central tendon develop from three sources: the septum transversum, the pleuroperitoneal folds, and the somites.
What are the openings of the diaphragm?
There are a number of openings in the diaphragm through which structures pass between the thorax and abdomen. There are three large openings — one for the aorta, one for the esophagus, and one for the inferior vena cava (the caval opening), plus a series of smaller ones.
What Aponeurosis means?
aponeurosis, a flat sheet or ribbon of tendonlike material that anchors a muscle or connects it with the part that the muscle moves. The aponeurosis is composed of dense fibrous connective tissue containing fibroblasts (collagen-secreting spindle-shaped cells) and bundles of collagenous fibres in ordered arrays.

What is the function of central tendon of the diaphragm?
When it contracts, it flattens, increasing the intrathoracic volume and thereby allowing air to enter the lungs. The central tendon is an aponeurosis which forms the top of the dome-shaped diaphragm. It blends with the fibrous pericardium above, helping to maintain it in place.
