---|---|
where is the heart? | middle mediastinum |
structures of superior mediastinum | great vessels - aortic arch - brachiocephalic artery - common carotids - subclavian others - trachea - esophagus - vagus - thoracic duct - brachioceplahic veins |
structures of anterior mediastinum | thymus |
structures of posterior mediastinum | DATES -descending aorta - azygos & hemiazygos veins - thoracic duct - esophagus - sympathetic chain - splanchnic nerves - vagus |
external features of heart | SVC IVC 2 pulmonary arteries 4 pulmonary veins arch of arota |
where does the arch of aorta end | T4/5 - sternal angle |
branches of aorta | brachiocephalic trunk - right common carotid - right subclavian left common carotid left subclavian |
moderator band | seen in prenatal ultrasound to locate RV |
