root
visceral and parietal
Regions of the parietal pleura?
costal pleura, diaphragmatic pleura, mediastinal pleura, cervical pleura
What lines the interior of the thoracic wall/ribs?
costal pleura
What lines the superior surface of the diaphragm?
diaphragmatic pleura
What lines the mediastinum?
mediastinal pleura
What extends superior to the 1st rib?
cervical pleura
What is between the ribs and the diaphragm?
costodiaphragmatic recess
The costal pleura and the diaphragmatic pleura are ____ and make a sharp angle ____. The space at this acute angle below the inferior border of the lung is called the ______ ____ and the angle is sharp enough to allow the two ____ ____ to touch.
continuous, inferiorly
costodiaphragmatic recess
parietal pleurae
Where is the mediastinal parietal pleura and visceral pleura continuous?
the pleural sleeve (which encloses the root)
-between the lung and heart
Right lung: through the pleurae it abuts the thoracic wall
costal surface
Right lung: through the pleurae it abuts the mediastinum and pericardium
mediastinal surface
Right lung: through the pleurae it abuts the superior surface of the diaphragm
diaphragmatic surface
Right lung: the most superior area of the superior lobe that extends superior to the first rib into the neck region
apex
Right lung: superior to the oblique and horizontal fissures, more anterior
superior lobe
Right lung: inferior to the horizontal fissure, superior to the oblique fissure, homologous to the lingula of the left lung, MOST anterior
middle lobe
Right lung: inferior to the oblique fissure, more posterior
inferior lobe
Separates the inferior lobe from the other two lobes, this is the ____ border of the _____ lobe.
oblique fissure
superior border of the inferior lobe
Separates the superior and middle lobes, minor or transverse fissure
horizontal fissure
The oblique fissure is generally found deep to the ____ laterally and the _____ anteriorly. The horizontal fissure is found deep to the _____ anteriorly..
5th rib laterally
6th cartilage anteriorly
4th rib and costal cartilage
Through the thin sheet of mediastinal pleura, the ____ encloses the heart between the two lungs.
pericardium
What passes anterior to the root of the lung within the surface of the pericardium?
phrenic nerve and pericardiacophrenic vessels
What passes posterior to the root of the lung?
vagus nerve
The lung is curved ____ around the ____ shaped mediastinum.
concave
convex-shaped
The structures of the root of the right lung have a directly _____ trajectory while the structures of the root of the left lung have a slightly _____ trajectory. The root of the left lung is more ____ and covered by the _____.
lateral
posterolateral
posterior
heart/mediastinum
Right lung: sharp, aims into the narrow costomediastinal recess
anterior border
Right lung: broad, fills int he paravertebral gutter
posterior border
Right lung: sharp, aims into the narrow costodiaphragmatic recess
inferior border
Right lung: anterioinferior to hilum
cardiac impression
Right lung: vertical, posterior to hilum down to inferior border
esophageal impression
Right lung: arches over the hilum to enter the superior vena cava
arch of the azygos vein impression
Right lung: anterior to hilum, from anterior border superiorly
superior vena cava impression
Left lung: sharp, aims into the narrow costomediastinal recess
anterior border
Left lung: dip in the anterior border, accommodates the presence of heart and forms the obvious lingula
cardiac notch
Left lung: tongue-like extension of the superior lobe, shape is enhanced by the cardiac notch
lingula
Left lung: broad, fills in the paravertebral gutter
posterior border
Left lung: sharp, aims into the narrow costodiaphragmatic recess
inferior border
Left lung: much deeper than the right, anterinferior to hilum
cardiac impression
Left lung: arches over the hilum superiorly
aortic arch impression
Left lung: inferior continuation of the arch posterior and inferior to the hilum
thoracic aorta impression
Thick walled, cartilaginous, in the hila of the lung
primary (main) bronchus
inferior point of the hilum, lower than arteries
inferior pulmonary vein
along the anterior edge of the hilum, anterior to arteries
superior pulmonary vein
What is found sitting on the surface of the bronchus?
bronchial artery
