Thoracic plane (mnemonic)
A handy mnemonic to remember the structures found at the level of the thoracic plane (also known as the plane of Ludwig) is:
- CLAPTRAP
- RAT PLANT
Mnemonic
CLAPTRAP
- C: cardiac plexus
- L: ligamentum arteriosum
- A: aortic arch (inner concavity)
- P: pulmonary trunk
- T: tracheal bifurcation (carina)
- R: right-to-left movement of the thoracic duct (posterior to the esophagus)
- A: azygos vein drains into SVC
- P: pre-vertebral fascia and pre-tracheal fascia end
RAT PLANT
- R: rib 2
- A: aortic arch
- T: tracheal bifurcation
- P: pulmonary trunk
- L: ligamentum arteriosum
- A: azygos vein drains into SVC
-
N: nerves
- loop of recurrent laryngeal nerve
- parasympathetic: contributions to the cardiopulmonary plexuses
- sympathetic: branches of the cardiopulmonary splanchnic nerves
- T: right-to-left movement of the thoracic duct
