Pleura ( Handout ) Flashcards
Inner membrane of the lung
A. Parietal
B. Visceral
B. Visceral
Outer membrane of the lung
A. Visceral
B. Parietal
B. Parietal
Insensitive to pain because it receives no nerves of general sensation
Visceral pleura
Visceral pleura receives an autonomic nerve supply from
Pulmonary plexus
3 compartments of the thoracic cavity
R pulmo cavity
L pulmo cavity
Mediastinum
Closely covers the lungs including the fissures
Visceral pleura
Adheres firmly to the lungs and provides the lungs with smooth slippery surface
Visceral pleura
Lines the pulmonary cavities
Parietal pleura
Pleura that is thicker than the other
Parietal thicker than visceral
Continuous with the parietal pleura at the hilum of the lung
Visceral pleura
Sensitive to pain, touch, and pressure
Parietal pleura
Nerves of the parietal pleura
Intercostal nerves
Phrenic nerve
Innervates the costal pleura and the peripheral part of the diaphragmatic pleura
Intercostal nerves
Innervates the mediastinal pleura and the central part of the diaphragmatic pleura
Phrenic nerve
Parts of the parietal pleura
Costal
Mediastinal
Diaphragmatic
Cervical
Parietal pleura: covers the internal surfaces of the thoracic wall A. Costal B. Mediastinal C. Diaphragmatic D. Cervical
A. Costal
The costal pleura is separated from the internal surfaces of the thoracic wall by?
Endothoracic fascia
Parietal Pleura: covers and forms the lateral boundary of the mediastinum A. Costal B. Mediastinal C. Diaphragmatic D. Cervical
B. Mediastinal
Parietal Pleura: continuous with the visceral pleura at the hilum of the lung A. Costal B. Mediastinal C. Diaphragmatic D. Cervical
B. Mediastinal
Parietal Pleura: covers the thoracic surface of the diaphragm A. Costal B. Mediastinal C. Diaphragmatic D. Cervical
C. Diaphragmatic
Connects the diaphragmatic pleura with the muscle fibers of the diaphragm
Phrenicopleural fascia
Parietal Pleura: dome-shaped cap that covers the apex of the lungs A. Costal B. Mediastinal C. Diaphragmatic D. Cervical
D. Cervical
The summit of the cervical pleura is ________ inches superior to the level of medial third of clavicle
1-1.5 inches
The cervical pleura is reinforced by
Sibson’s fascia or suprapleural membrane
Where the parietal pleura abruptly changes direction
Lines of pleural reflection
What are the lines of pleural reflection?
Anterior / sternal
Inferior / costal
Posterior / vertebral
