Q

The costomediastinal recess is a reflection of parietal pleura at the junction of _ and _ pleura.

A

costal and mediastinal

23
Q

The costomediastinal recess is filled by the _ border of the lung during strenuous breathing.

A

anterior

24
Q

The costodiaphragmic recess is a reflection of the parietal pleura at the junction of _ and _ pleura.

A

costal and diaphragmic

25
Q

The costodiaphragmic recess is filled by the _ border of the lung during strenuous breathing.

A

inferior

26
Q

The pleural cavity is the space between the _ and _ pleura.

A

Visceral
Parietal

27
Q

The pleural cavity is maintained at a state of continuous _ pressure

A

negative

28
Q

T/F The pleural space lacks capillaries and is filled with air.

A

False, it is filled with a thin fluid and is capillary dense

29
Q

The negative pressure in the pleural cavity keeps the _ pleura and the lung adjacent to the _ pleura ( and thus to the thoracic wall and diaphragm)

A

visceral pleura
parietal pleura

30
Q

Due to negative pressure in the pleural cavity, any movement in the _ _ and _ will result in corresponding movement of the lung

A

thoracic wall and diaphragm

31
Q

If negative pressure is lost in the pleural cavity the lung would collapse due to its inherent _ ( causing internal _ fibers to shorten).

A

elasticity
elastic

32
Q

Collapse of a lung is called _ and the presence of air in the pleural cavity is called _.

A

atelectasis
pneumothorax

33

Q

The mediastinum extends from the level of the _ _ superiorly to the _ inferiorly.

A

Thoracic Inlet
Diaphragm
