Flashcards in Pleurae and Pleural Cavities Deck (20):
1

What are the three (3) subdivisions of the thoracic cavity?

1) 2 Pleural cavities
2) Mediastinum

2

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

3

What is the thin membrane that lines the inner surface of the thoracic cavity and covers the surface of the lungs?

Pleura

4

Which layer of the plerua will line the inner surface of the thorax?

Parietal Pleura

5

Which layer of the pleura will invest the lung?

Visceral Pleura

6

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

7

What is the potential space between the parietal and visceral pleurae?

Pleural Cavity

8

What is the function of the pleural fluid?

To lubricate the pleurae to minimize friction between the parietal and visceral pleurae

9

Whe function of the pleura fluid will allow for what?

Movement of the Lungs

10

What is the largest part of the parietal pleura?

Think back to lab :)

Costal

11

The layer of the partial pleura that will be a dome over the thorax at the base of the neck?

Cervical

12

Where are the pleura cavities found?

Between the two folds of the parietal pleura

13

What do the pleural recesses allow for?

Expansion of the lungs during inspiration

14

What is the space where the costal and diaphragmatic pleurae meet along the mid-axillary line?

Costodiaphragmatic Recess

15

What is the space formed where the costal and mediastinal pleurae meet?

Costomediastinal Recess

16

When fluid accumulates in the costodiaphragmatic recess, what is performed to remove the fluid and where is this done?

Thoracentesis

-Performed in the 9th intercostal space during expiration (with an 18-gauge spinal needle-little emergency medicine note)

17

What is the blood supply to the parietal pleura?

1) Intercostal Arteries
2) Internal Thoracic Artery
3) Phrenic Artery

18

What is the blood supply to the visceral pleura?

Bronchial Artery

19

What is the innervation to the parietal pleura?

1) Intercostal nerves
2) Subcostal Nerve
3) Phrenic Nerve

20

What is the innervation to the visceral pleura?

Trick question, the visceral pleura has no sensory innervation
