Block 2 Thoracic Wall, Pleura Lungs, Diaphragm Flashcards
this is more spacious than thoracic inlet and is inferior near 12th rib
thoracic outlet
3 parts of sternum
manubrium, body, xiphoid process
midline superior notch of sternum
jugular notch
manubrium articulates with sternum at blank
sternal angle (angle of louis)
body of sternum has attachment of these
costal cartilage 2-7
costal cartilage 2-7 articulations are blank type joints
gliding
ribs 8-10 attach to blank so they are blank ribs
superior costal cartilages, false
ribs 11,12 are blank
floating
head and neck is closer to the blank
vertebrae
typical rib articulates with blank vertebra and the vertebra superior to it
same numbered
strongest rib
1
neurovascular bundles are located blank to the rib
inferior
three muscles of intercostal spaces
external, internal, innermost
ribs 7-10 move in a blank manner which increases blank diameter of chest
pump handle, a-p
ribs 8-10 move in a blank manner increasing the blank dimension
bucket handle, M-L
two main sources of arterial supply
intercostal vessels, branches of subclavian/axillary arteries
blank intercostal arteries arise from the thoracic aorta for the lower 9 intercostal spaces
posterior
the upper two intercostal spaces are supplied by the blank intercostal artery
superior
posterior intercostal artery ambiguously becomes blank
anterior intercostal artery
anterior intercostal artery anastamoses with the
internal thoracic artery
external oblique fiber orientation
superolateral
internal oblique fiber orientation
superomedial
all intercostal muscles help with blank
inspiration/expiration
two terminal branches of itnernal thoracic artery
musculophrenic, superior epigastric
external intercostal becomes a membrane in the blank
anterior
internal intercostal muscle becomes membrane in blank
posterior
innermost intercostals are locatted only at blank
midaxillary line (laterally)
posterior to sternum, this muscle runs transversely from posterior sternum to rib and is in the same plane as innermost intercostals
transversus thoracis
larger ramus of spinal nerve
ventral
intercostal nerve is simply a continuation of a blank
ventral ramus
lymph nodes that drain thoracic wall
internal thoracic group
pleural sac has visceral and parietal layer just like blank
peritoneum
pleural cavity is just like blank
peritoneal cavity
there is blank in pleural cavity
serous fluid
top of lung that goes into neck region
cupula
blood in pleural cavity
hemothorax
air in pleural cavity
pneumothorax
parietal pleura reflects off the diaphragm and onto the inner chest wall in a recess termed the blank
costodiaphragmatic recess
clavicles, sternum, first ribs, vertebral column forms this
thoracic inlet
oblique fissure of lung is aka blank fissure
major
horizontal fissure of lung separates the blank and blank lobe and is aka blank
superior, middle, minor
left lung only has blank fissure
oblique
lung extends to blank rib in order of anterior, lateral, posterior
6,8,10
superior to inferior in lung
pulmonary artery, bronchus, pulmonary vein
pleura of the lung extends to blank rib in order of anterior, lateral, posterior
8,10,12
rule of 2’s is important when performing a blank
pleural tap
superior surface of diaphragm is arterial supplied by blank
musculophrenic, pericardiophrenic
inferior surface of diaphragm is arterial supplied by blank
inferior phrenics
periphery of diaphragm is arterial supplied by blank
intercostals
inferior vena cava passes through the diaphragm via the blank at t8
central tendon
esophagus passes through the blank at t10
esophageal hiatus
aorta passes blank to the diaphragm at t12
posterior
phrenic nerve does motor supply to blank and sensory supply to blank
diaphragm, central tendon
