Cards in this deck (19)
- 1Thoracic cavity borderssternum, ribs, vertebrae, diaphragm
- 2Diaphragm origin, insertionxiphoid process, bottom 6 costal cartilages, median arcuate ligament
- 3Right and left cruaL1/L2: left crua
L2/L3: right crua
bodies of vertebrae - 4Things that pass through the diaphragmdescenting aorta, esophagus, inferior vena cava
- 5diaphragm blood supply and innervationinternal thoracic artery
phrenic nerve, C3, 4, 5 - 6visceral and parietal pleuraParietal (parental) on outside
visceral on lungs - 7Visceral pleuraMicrovili that release HA to lubricate
HA binds water to increase lubrication and tension - 8Parietal pleura blood supply and innervationblood supply: visceral and intercostal branches - descending aorta
nerve: phrenic nerve or intercostal nerves - 9Where does liquid fill in thoracic cavity?Costodiaphragmatic, costomediastinal spaces
above 8th rib to drain liquid - pleural tap - 10oblique and horizontal fissuresoblique: divides upper and lower lobe
horizontal: in right lung divides upper and middle - 11Lingula, cardiac notchboth on left lung, where the upper lobe extends, and where the lung makes room for heart
- 12Segments of the lung10 per lung, function separate of each other, one can be blocked off/ removed
- 13Hilum of left lungaortic arch sulcus, esophageal sulcus
- 14Right lung hilumsulcus for azygos, esophagus, superior & inferior vena cava, subclavian artery
- 15secondary and tertiary bronchi carina10 tertiary in each lung, 2 secondary in left lung, 3 in right
carina where bronchi split, innervated and aggressive coughing if touched - 16bronchi to bronchiolesdecrease in cartilage
increase in smooth muscle - 17blood supply to lungsbronchial arteries : from the descending aorta
- 18Parasympa lung innervationvagus nerve (CN X)
bronchioconstrictors - 19sympa lung innervation3rd and 4th ganglia of trunk
