Lungs And Pleura Flashcards
Lines membranes of the lungs
Pleura
Pleural cavity is invaginated by growing lung bud during which week of embryonic development
3rd week
The pleura deviates laterally at the level of which ribs
4th and 5th
Inferior part of parietal pleura at the midclavicular line is at the level of which rib
8th
Pleural surface adherent to all surfaces of the lungs
Visceral pleura
The parietal pleura adheres to these structures
Thoracic wall, mediastinum, diaphragm
The parietal amd visceral pleura are continuous at what structure
Hilus of lung
Empty double layer of pleura which is the apposition of visceral and parietal pleura inferior to root of the lung
Pulmonary ligament
Potential space between pleural layers
Intrathoracic cavity
Lubrication between parietal and visceral pleurae
Thin film of extracellular fluid
Function of extracellular fluid in pleura
Provides surface tension which keeps lungs inflated
Regions of parietal pleura applied at sites of pleural reflection where lung fails to fill pleural cavity
Pleural recess
Pleural recess between costal and diaphragmatic pleura
Costodiaphragmatic recess
Recess where needle is inserted to avoid pneumothorax
Costomediastinal recess
Innervation of parietal pleura
1st to 12th intercostal nerves
Innervation of visceral pleura
Pulmonary plexus
Innervation of peripheral diaphragmatic pleura
Lower intercostal nerves
Innervation of central diaphragmatic pleura/mediastinal pleura
Phrenic nerve
Potential space between visceral and parietal pleura
Pleural cavity
Capillary layer of serous fluids in pleural cavity is produced by?
Mesothelium
What is the effect of excess air entering the pleural cavity
Surface tension adhering visceral and parietal pleura is broken, and lung collapses due to elastic recoil
Air in the pleural cavity
Pneumothorax
Blood in the pleural cavity
Hemothorax
Fluid in the pleural cavity
Hydrothorax
