1

ribs 1-7 8-10 11-12

true false - continuous costal margin floating

1

pectus excavatum

overgrowth of costal cartilage pushes sternum inward = caved in chest

3

ventilation mechanics of ribs and sternum

sternum - pump handle effect costovertebral joints - bucket handle effect

4

where to run chest tube

lateral upper chest wall on top of a rib to avoid intercostal VAN

5

ectopia cordis

heart is located outside of chest wall

6

great vessels exiting heart are posterior to

sternal angle of louis (at 2nd rib)

6

what innervates diaphragm?

phrenic nerves

6

coarctation of aorta

stenosis of aorta collateralization --> notching of the ribs

7

where does intercostal neurovascular bundle lay?

between internal and innermost intercostal muscles

9

pleura covering the lung apex?

cupola

10

if the pleural space is broken

air is drawn in due to negative pressure =pneumothorax - air collapses lung

11

how to treat cardiac tamponade?

pericardiocentesis

11

pectus carinatum

pigeon chest - sternum and ribs protrude due to overgrowth of cartilage

13

diaphragm is HIGH at what intercostal space?

4th, level of nipples

14

abnormally widened mediastinum

trauma! produces hemorrhage from lacerated great vessels torn aorta?! or malignant lymphoma/hypertrophic heart can also widen it

15

lung apex is above

clavicle

17

poland syndrome

abcense of sternocostal head of pec major + shortened upper extremities and digit anomalies

18

phrenic nerve injury

paralysis of the injured side diaphragm paralyzed side will ascend during inhalation since it is pushed by organs displaced by the other descending side paralyzed side descends in exhalation due to positive pressure in lungs
