Respiratory Flashcards
Lines walls of the thoracic cavity
Parietal pleura
Lines surface of the lung
Visceral pleura
Space between the visceral and parietal pleura
Pleural space
Located inferior to the root of the lung, area of fusion between the parietal and visceral pleura
Pulmonary ligament
What are the 4 parts of the parietal pleura?
Cervical
Costal
Diaphragmatic
Mediastinal
To what landmarks does the parietal pleural layer extend to at mid respiration?
Anterior down to rib 8
Laterally down to rib 10
Posteriorly down to T12
To what landmarks does the visceral pleural layer extend to at mid respiration?
Anterior down to rib 6
Laterally down to rib 8
Posteriorly down to T10
Which nerve(s) innervate the parietal pleura?
Intercostal nerve
Phrenic nerve
What are the lateral inferior corners of the thoracic cavity called?
Costodiaphragmatic recess
Inflammation of the pleural layers
Pleurisy
Build up of fluid in the pleural cavity (give two examples)
Pleural effusion
Ex. Hydrothorax, hemothorax
Between what intercostal spaces should you aim for during a thoracentesis? Why?
Intercostal spaces 8-10 at the midaxillary line in order to avoid hitting lung
What is an sign of a severe pneumothorax that can be seen without imaging?
A shifted trachea from midline
Collapsed lung
Pneumothorax
At what level will you find the horizontal fissure of the right lung?
4th intercostal space
At what level will you find the oblique fissures on the left and right lungs?
T4-T6 intercostal spaces
What does the horizontal fissure separate in the lung?
Superior lobe from middle lobe on RIGHT lung
What does the oblique fissure separate in the lungs?
The inferior lobes from the middle (right lung) or superior (left lung) lobes
