Diaphragm structures - Lung relations Flashcards
structure perforating diaphragm (an where)
T8: IVC
T10: esophagus vagus
T12: aorta, thoracic duct, azygos vein
esophagus perofrates diaphragm at
T10
azygos vein perforates diaphragm at
T12
ivc perforates diaphragm at
T8
vagus perforates diaphragm at
T10
aorta perforates diaphragm at
T12
thoracic perforates diaphragm at
T12
Diaphragm is innervated by
C3, C4, C5
PHRENIC NERVE
causes of diaphragm irritation (that cause pain)
air or blood in peritoneal cavity
pain from diaphragm irritation can be refereed to (and how)
- shoulder (C5)
2. trapezius ridge (C3, C4)
the common carotid bifurcates at (area by vertebrate)
C4
the trachea bifurcates at
T4
the abdominal aorta bifurcates at
L4
if you aspirate a peanut while upright: it enters
lower portion of right inferior lobe
if you aspirate a peanut while supine: it enters
superior portion of right inferior lobe
Right lung has … lobes
3
Left lung has …. lobes
2 lobes
AND LINGULA
which lung is more common site for inhaled foreign body and why
Right lung because the right main stem bronchus is wider and more vertical than left
left vs right lung
right has 3 lobes
left lung has 2 lobes and lingula
lingula is homolog of right middle lobe
Lingula is homolog to
right middle lobe
right main stem bronchus vs left main stem bronchus
the right stem bronchus os wider and more vertical than left
instead of middle lobe, the left lung has
a space occupied by the heart
the relation of the pulmonary artery to the bronchus at each lung hilum is described by
mnemonic: RALS
- right: anterior
- left: superior
bifurcation at L4
abdominal aorta
bifurcation at T4
trachea
bifurcation at C4
common carotid
