At what location does the Larnygeal prominence occur?

A

C5

34
Q

At what location does the cricoid cartilage occur and the trachea begin?

A

Describe the lobed structure of the left lung

A

Superior lobe, oblique fissure, inferior lobe, cardiac notch, lingula

37
Q

What is the lingula?

A

The homologue structure of the middle lobe on the left lung

38
Q

What is the lung hilum?

A

The area located on the medial/mediastinal surface of the lung

39
Q

What is the root of the lung?

A

Is the group of structures (bronchus, artery, veins, lymphatics, nerves) that enter or leave the lung hilum

40
Q

What are the pleura of the lungs?

A

Membranes that surround the lungs

41
Q

What pleura adheres to the interior of the rib cage?

A

Parietal pleura

42
Q

What pleura adheres to the the lungs themselves?

A

Visceral pleura

43
Q

What fills the pleural cavity?

A

Pleural fluid (approx. 3ml)

44
Q

What is the region of space between the left and right lung called?

A

Mediastinum

45
Q

The root of the right lung has an additional structure, what is this?

A

An additional bronchus called the eparietal bronchus (the right primary bronchus is called the hyparietal bronchus)
