Cervical
What is the costal pleura of the lungs innervated by
intercostal nerves

phrenic
What is the pulmonary ligament
thin fold of reflected pleura that extends inferiorly from the root of the lung
What does the pulmonary ligament allow for
accommodates expansion
What is Sibson’s fascia
supra pleural membrane
thickening of the endothoracic fascia that protects the cupola of the lung
What are the different pleural reflections
sternal
costal
vertebral
What are the two pleural recesses
costomediastinal
costodiaphragmatic
What is the costodiaphragmatic recess
diaphragmatic pleura turning back to costal pleura
Where is the costomediastinal recess found
over the heart
what do the pleural recesses contain
fluid accumulation
What space will most likely collect fluid from the lungs
costodiaphramatic recess

parietal 8
What levels will the visceral and parietal pleura be seen in the scapular line
visceral 10
parietal 12
How many lobes are in the left lung
3
How many loves are in the right lung
2
What level will the oblique fissures of the lungs be found
midclavicular: 6th rib
Midaxillary: 5th rib
Scapular: 4th
What lung has a horizontal fissure and where is it found
right lung
4th rib
Where do you auscultate the right superior love
above 3rd rib midclavicular line
Where do you auscultate the middle lobe
below 4th rib, midclavicular line
Where do you auscultate the inferior lobe of the right lung
below 5th rib on scapular line of posterior chest wall
Where do you auscultate the left superior lobe
above 5th rib midclavicular line
Where do you auscultate the left inferior lob
below 5th rib on posterior chest wall
What structures leave an impression on the left lungs
cardiac impression
aorta
What structures leave an impression on the right lungs
cardiac impression
SVC
IVC
esophagus
What lung will have a cardiac notch
left lung
What does the trachea branch into
right and left primary bronchi
What will the right primary bronchus branch into
3 secondary bronchi
What will the 3 right secondary bronchi branch into
10 tertiary bronchi
What will the left primary bronchus branch into
2 secondary bronchi
What will the 2 left secondary bronchi branch into
10 tertiary bronchi
What portion of the lung does TB typically target
apical segments
What main bronchus is most commonly aspirated into
right
How can you orient yourself when looking at a trachea
flat aspect where cartilage is absent is posterior
What is the cough reflex efferent
vagus, phrenic, and intercostals
What is the cough reflex afferent
vagus
What is the function of pulmonary arteries and veins
gas exchange (carry blood to and from the heart to the lungs and back)
What is the function of bronchial arteries and veins
supply the lung tissue with nutrients and drain the lungs
What are the lymph nodes of the lungs
pulmonary
bonchiopulmonary
inferior and superior trachiobronchial
paratrachial
Where are pulmonary lymph nodes found
in the lung
Where are bronchipulmonavry lymph nodes found
in the hilum
Where are inferior trachiobronchial lymph nodes found
under carina
Where are superior tracheobronchial lymph nodes found
above carina
Where are paratracheal lymph nodes found
along the sides of trachea
Where does the right lung drain lymph wise
to right jugulovenous angle
Where does the left inferior lung drain lymph wise
carinal nodes to right jugulovenous angle
Where does the left superior lung drain lymph wise
left jugulovenous angle
What is suggested by enlarged paratracheal lymph nodes on the left
infection or cancer in left upper lobe
What layers are traversed in thoracocentesis
skin superficial fascia external intercostals internal intercostals innermost intercostals endothoracic fascia parietal pleura
What structures are at risk during thoracocentesis
VAN complex intercostals
lung
liver
diaphragm
What space is thoracocentesis done at
8-9th intercostal space in mid-axillary line
What is pneumothorax
disruption of parietal pleura leading to disruption of vacuum
What is spontaneous penumothorax
pneumothorax with no associated trauma
