|
|
|
what is the stroma/framework of the lungs
|
fibroelastic tissue
|
|
|
the uppermost portion of the lung
|
Apex-cupula-cupola
It projects outward through the superior thoracic aperture into the base of the neck |
|
|
Where does the apex of the lung sit
|
about 1 inch above superior throacic aperture and posterior to the medial 1/3 of the clavicle
|
|
|
what is the lowermost portion of the lung
|
the base- it sits on the diaphragm and is concave in shape
|
|
|
3 external surfaces associated with the lungs
|
Costal Surface
Medistinal Surface Diaphragmatic Surface |
|
|
Costal surface
|
portion of the lung lying adjacent to the rib cage(entire lateral aspect)
|
|
|
Mediastinal Surface
(medial surface) |
portion lying adajacent to the mediastinum (the medial surface)of the lung
|
|
|
Diaphragmatic Surface
|
portion that rests on top of the diaphragm- concave in shape to accommodate the dome-shaped diaphragm
|
|
|
3 borders associated with the lungs
|
Anterior border

|
|
Anterior Border of lung
|
thin narrow wedge-shaped peice of lung tissue foundalong anterior medial edge located where costal surface and medial surface meete anteriorly- extends from apex to base of lung
|
|
|
Posterior Border of lung
|
Broad rounded area along the posterior medial edge located where costal surface and mediastinal surface meet posteriorly- extends from apex to the base of the lung
|
|
|
Inferior Border
|
A thin wedge-shaped piece of lung tissue located along the base of the lung where diaphragmatic surface meets costal and mediastinal surface - it curves and follows along with the shape of the lung base
|
|
|
