Pleura and Mediastinum Flashcards
list the 15 major structures in the superior mediastinum
4 arteries- arch of aorta, brachiocephalic, L common carotid, L subclavian
4 nerves- vagus and phrenic
3 veins- SVC, R and L brachiocephalic
2 tubes- trachea and esophagus
1 gland- thymus
1 duct- thoracic duct
when the vagus nerve loops, what does it turn into?
recurrent laryngeal nerve
which part of the serosal pleuarl membrane has pain sensation?
parietal
what is the recess regarding the lungs?
areas where the lung doesn’t go all the way down
the cardiac plexus is _________ innervation and ________ bronchioles and vessels
sympathetic
dilates
the vagus nerve is ______________ innervation and _________ bronchioles
PS
constricts
this is where vessels enter and leave the lung and where the primary bronchus is located
hilum
this condition occurs when the posterior cardinal vein fails to migrate over the apex of the lung and penetrates it instead
azygos lobe
this condition includes a bell shaped thorax, reduced lung volume, fine granular appearance, and air periphery bronchograms
respiratory distress syndrome (RDS)
in fetal circulation, this structure is between the right and left atria
foramen ovale
in fetal circulation, this structure is between the pulmonary arteries and the aorta
ductus arteriosus
in fetal circulation, this vessel sends oxygenated blood from the placenta to the heart
umbilical vein
in fetal circulation, this vessel is a connection between the umbilical vein and the IVC
ductus venosus
this is incomplete closure of the foramen ovale, leading to a L–> R shunt of oxygenated blood
atrial septal defect
this is the MC cause of cardiac defects and causes severe pulmonary HTN
ventricular septal defect
