Mediastinum and Heart Sanjaya Adikari Department of Anatomy
Thoracic cavity Thoracic cavity communicates –with the neck through the superior thoracic aperture –with the abdominal cavity through the inferior thoracic aperture (closed by the diaphragm)
What is thoracic outlet syndrome ? Thoracic inlet/ Superior thoracic aperture Inferior thoracic aperture
What are the structures that enter or leave the thoracic cavity?
