What are the 2 divisions of the pulmonary cavity
- Right hemi-thorax
2. Left hemi-thorax
What is the function of a serous membrane
It produces a small amount of fluid to lubricate movement of an organ within the cavity
What is the serous membrane called in the pulmonary cavities
Pleura
What are the 2 different types of pleura
- Parietal pleura
2. Visceral pleura
What does the parietal pleura line and what are the 4 different sections/parts
It lines the pulmonary cavity
- Cervical
- Costal
- Diaphragmatic
- Mediastinal
What does the visceral pleura line
It covers the surface of the lung
What is the pulmonary ligament
Sleeve of pleura that hangs down below the lung root
What is endothoracic fascia and what is its function
It is a layer of connective tissue that attaches the costal parietal pleura to the thoracic wall
What is the suprapleural membrane and where does it attach
It is a tough fibrous membrane that attaches to the 1st rib and the transverse process of C7
What is the function of the suprapleural membrane
It stops the lungs inflating beyond their boundary within the pulmonary cavity
Where will parietal pleura always be in relation to visceral pleura
It will always be 2 ribs below
What is created when parietal pleura extends over the dome of the diaphragm
Costodiaphragmatic recesses
Where are costomediastinal recesses found
Posterior to the sternum
What is the superior section of a lung called
The apex
Name the 3 surfaces of the lungs
- Mediastinal
- Diaphragmatic
- Costal
Name the 3 borders of the lungs
- Anterior
- Posterior
- Inferior
