Question 6

Compare Visceral pleura vs. Parietal pleura [2]

Answer 6

[Visceral Pleura] adheres to lung tissue & is only continuous with Parietal Pleura at Lung’s HILUM

vs.

Parietal Pleura is continuous with [Visceral Pleura] at Lung’s HILUM AND has 3 surfaces < Costal vs. Diaphragmatic vs. Mediastinal >

Question 7

Name the 6 surface projections of the Parietal Pleura

Answer 7

[Parietal Pleura]
rib 2-reaches midline
rib 4(L) - Bare

Rib 6 = reflects along costal arch
Rib 8 = mid-clavicular line

Rib 10 = mid-axillary line

rib 12 = Behind pleura

Question 8

Name the 5 surface projections of the VISCERAL Pleura

Answer 8

[VISCERAL Pleura]
rib 2-reaches midline
rib 4(L) - CARDIAC NOTCH

Rib 6 = mid-clavicular line
Rib 8 = mid-axillary line

Rib 10 = Behind pleura
