Flashcards in Pleurae and Pleural Cavities Deck (20):
What are the three (3) subdivisions of the thoracic cavity?
1) 2 Pleural cavities
What is the mediastinum?
The area between the two pleura cavities that will house the heart, the great vessels, the esophagus, the trachea, and other mid line strucutres
What is the thin membrane that lines the inner surface of the thoracic cavity and covers the surface of the lungs?
Which layer of the plerua will line the inner surface of the thorax?
Which layer of the pleura will invest the lung?
T/F: The parietal and visceral pleura are one, connected piece of tissue?
True: The parietal pleura reflect back to become the visceral pleura at the root of the lung
What is the potential space between the parietal and visceral pleurae?
What is the function of the pleural fluid?
To lubricate the pleurae to minimize friction between the parietal and visceral pleurae
Whe function of the pleura fluid will allow for what?
Movement of the Lungs
What is the largest part of the parietal pleura?
Think back to lab :)
The layer of the partial pleura that will be a dome over the thorax at the base of the neck?
Where are the pleura cavities found?
Between the two folds of the parietal pleura
What do the pleural recesses allow for?
Expansion of the lungs during inspiration
What is the space where the costal and diaphragmatic pleurae meet along the mid-axillary line?
What is the space formed where the costal and mediastinal pleurae meet?
When fluid accumulates in the costodiaphragmatic recess, what is performed to remove the fluid and where is this done?
-Performed in the 9th intercostal space during expiration (with an 18-gauge spinal needle-little emergency medicine note)
What is the blood supply to the parietal pleura?
1) Intercostal Arteries
2) Internal Thoracic Artery
3) Phrenic Artery
What is the blood supply to the visceral pleura?
What is the innervation to the parietal pleura?
1) Intercostal nerves
2) Subcostal Nerve
3) Phrenic Nerve
