Definition
Regions of parietal pleura adjacent to other parietal pleura where the lung fails to fill the fleural cavity.
-Pleural cavities are larger than lung volumes.
-during deep inspiration the lung parenchyma expands to, but never completely fills, these recesses. |

Definition
| 1st-12th intercostal nerves. |

Term
| Peripheral diaphragmatic pleura innervation |
|
Definition
Lower intercostal nerves
-pain from irritation may be referred to the lateral throacic & anterior abdominal walls, because lower intercostal nerves innervate those regions. |

Term
| Central Diaphragmatic & Mediastinal Pleura Innervations |
|
Definition
Phrenic nerves
-pain may be referred by the distribution of nerves C 3-5 |

Definition
| Occurs if air enters & leaves the pleural cavity through the wound. This condition is accompanied by hyperexpansion of the chest wall on the normal side & mediastinal flutter, a slight shift of the mediastinal mass toward the normal side during inspiration & toward the injured side during expiration. |

Definition
Occurs if the wound acts as a check valve with air drawn into one pleural cavity during inspiration without expulsion of air from the pleural cavity during expiration.
-resulting increase in intrathoracic pressure permanently forces the mediastinal contents toward the normal side (mediastinal shift), thereby reducing the vital capacity of the normal lung. |

Term
| Glossopharyngeal nerve (CN IX) |
|
Definition
Innervate the carotid bodies & sinuses.
-helps monitor the PO2 in blood & changes its activity accodring to amount of O2 present at any given time.
-also monitors blood pressure & changes acitivity accordingly |

Innervates the aortic bodies & sinuses.
-Monitor changes in PO2 and changes its activity accordingly. |
