Thoracic Diaphragm: The thoracic diaphragm is a muscle that divides the thoracic cavity from the abdominal cavity and is a vital component of the act of breathing or respiration. The thoracic diaphragm contracts during inhalation, pulling air into the lungs. Exhalation occurs when the diaphragm relaxes, helping to force air out of the lungs. The thoracic diaphragm originates on the xiphoid process of the sternum, the lower six ribs, and the upper two to three lumbar vertebrae. It inserts on the central tendon of the diaphragm. It is innervated by the phrenic nerve and lower intercostal nerves.
Conditions that can afflict the thoracic diaphragm include diaphragmatic hernia, phrenic nerve injury, hiccups, rupture, tears, strains, myopathy, atrophy, infectious myositis, neuromuscular diseases, lacerations and contusions.
