Also asked, what rib level is the diaphragm?

The diaphragm is a double-domed sheet of skeletal muscle, located at the inferior-most aspect of the rib cage. It serves two main functions: Separates the thoracic cavity from the abdominal cavity (the word diaphragm is derived from the Greek 'diáphragma', meaning partition).

Likewise, what goes through the diaphragm? Three important structures pass through the diaphragm: the esophagus, and the two main blood vessels of the lower half of the body, the inferior vena cava, and the descending aorta. This is the opening for the inferior vena cava, the vena caval foramen. This is the opening for the esophagus, the esophageal hiatus.

Likewise, people ask, where does the diaphragm insert?

Embryology

  • Diaphragm Formation.
  • Insertion. The diaphragm inserts into a central tendon. The top surface of the tendon is partially connected to the lower surface of the fibrous pericardium.
  • Origin of Diaphragm. Sternal. The sternal part originates as 2 fleshy slips from the back of the xiphoid process.

What does the central tendon of the diaphragm attached to?

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.
