Thoracic Wall Flashcards
stages of clinical exam
inspection, palpation, percussion, auscultation
aortic valve heard at
2nd intercostal, R
pulm valve heard at
2 intercostal, L
tricuspid heard
5th intercostal, L
mitral valve heard
5th intercostal, L mid clavicular
thoracic cage features
semi ridged, muscle attachment, projection, help with breathing
t2/t3
pulm A and branch divide
t4/T5
sternal angle, divide superior and inferior mediastinum, 2nd ribs join, bifurcation of trachea and pulm trunk
true ribs
1-7
false ribs
8-10
floating ribs
11-12
which are movable joints in thoracic
costovertebral, costotransverse
rib dislocation
costal cart detach from sternum
rib separation
rib detach from costal cart
flail chest
mult farctures, ribs detach from chest wall, section moves inward on inspiration
cervical rib
extra, on 7th vertebrae, thoracic outlet syndrome
pointy chest is called
pectus carinatum
the three intercostal muscles
external, internal, innermost
intercostal membranes
anterior (external), posterior (internal)
anterior intercostal A splits into
muscular phrenic and superior epigastric
aorta gives off
posterior intercostal artery, > dorsal posterior
internal thoracic artery gives off
anterior intercostal
coarctation of aorta
narrowing, increases collateral flow, leads to rib notching
intercostal vessel main order
VAN
intercostal colorerai order
NAV
what part of intervertebral space do you aim thoracocentesis
MIDDLE/ just above upper border of ribs to miss main
anterior intercost vs posterior veins drain into what?
anterior> internal thoracic, posterior>azygous
accessory inspiration muscles
external intercostal, pecs, serratus
compartments of thoracic cavity
2 pulm (lung and pleura), central (mediastinum)
expiratory muscles
oblique, abs, scalènes
right lung
3 lobes, 2 fissures
left lung
2 lobes, one fissure, lingual, cardiac notch
parietal pleura lung
cercival and costal (intercostal n), mediation and diaper (phrenic)
visceral pleura of the lung (innervation )
autonomic n
pleursiy
inflamed pleura, rub, sharp pain,
what ribs join at sternal angle
2nd
intercostal nerve functions
innervate intercostal muscles, supply skin sensation, innervate costal parietal pleura, from venral rami
where is cardiac notch
left lung
where will aspirated food most likely go
right main stem bronchi
where does LLL drain?
R side trachea lymph nodes
hilar lymph nodes are called
bronchomediastinal
where do lungs extend
ribs 6, 8, 10
pleural reflection extends to
rib 8, 10.12
bare area
left 5th intercostal space left of sternum
pulmonary bleb
weekend outpourings, can rupture and cause spont pneumonia
vagus nerve functions
bronchoconstrict, promote secretion, relax blood vessels
sympa fiber functions
bronchodilator, inhibiting mucus, constrict blood vessels
phrenic nerve functions
motor diaphragm, sensory diaphragm and mediastinal pleura
Pulm embolism
block of pulm ARTERY of branch.
how are intercostal spaces numbered?
superior riv
which rib facet does not articulate with same vert number
superior- vertebrae above!
