Thorax 3 Flashcards
where does the right pulmonary artery pass
posterior to the ascending aorta and SVC before entering the root of right lung
in relation to the aortic arch and descending thoracic aorta where does the left pulmonary artery run
below aortic arch and anterior to descending thoracic aorta
what level is the transthoracic plane
T4 - divides the superior and inferior mediastinum
what is the ligamentum arteriosum
band of fibrous tissue connecting top of pulmonary bifurcation to bottom of arch of aorta
where does the thoracic aorta start
T4/T5
where is the aortic hiatus
T12
where does the azygos vein drain
right side into back of SVC
what does the azygos vein drain
right posterior thoracic wall
what does the hemiazygous vein drain
inferior left posterior thoracic wall
what does the accessory hemiazygous vein drain
superior left posterior thoracic wall
what level does the hemiazygous veins joint the azygos vein
T7
where does the right recurrent laryngeal loop
loops around the right subclavian artery
where does the left recurrent laryngeal nerve run
loops behind the arch of aorta and in the tracheal-esophageal groove
where does the right phrenic vein descend to
right brachiocephalic vein and SVC
anterior to the root of the right lung, across pericardium to the diaphragm
where does the left phrenic nerve descend
along the left side of the left subclavian
crosses left vagus nerve superficially as it approaches the aortic arch
crosses anterior to the root of the left lung
