Q

Where do the external intercostals run?

A
  • run lat. -> med
  • becomes membranous ant.
20
Q

Where do the internal intercostals run?

A
  • run med. -> lat
  • becomes membranous post.
  • covers outside costal groove
21
Q

What is located mostly laterally and covers the inside costal groove?

A

innermost intercostals

22
Q

What are the transversus thoracic & subcostalis?

A

incomplete layers deep to everything

23
Q

What muscles are responsible for inspiration?

A
  • int. intercostals
  • ext. intercostals
  • diaphragm
24
Q

What muscles are responsible for expiration?

A
  • int. intercostals
  • transversus spinalis
  • subcostalis
25
Q

The diaphragm is responsible for what percentage of breathing?

A

75%

26
Q

What does the phrenic nerve innervate (C 3/4/5)?

A

diaphragm & lungs

27
Q

What does the diaphragm do during inspiration & expiration?

A
  • inspiration -> contracts & lowers
  • expiration -> relaxes & raises
28
Q

What are the structures that pass through the diaphragm?

A
  • IVC -> 8th vertebrae
  • esophagus -> 10th vertebrae
  • aorta -> 12th vertebrae
29
Q

What lines the thoracic cavity?

A

parietal pleura (superficial to visceral pleura)

30
Q

What covers the lungs?

A

visceral pleura (deep to parietal pleura)

31
Q

What is the pulmonary ligament?

A

folded double layer of pleura

32
Q

What are recesses in the lungs?

A

when the pleura extends below the lungs; fluid can pool here

33
Q

What are the 3 lobes of the right lung?

A

superior, middle, & inferior

34
Q

What is the oblique fissure in the right lung?

A

separates sup. & inf. lobe

35
Q

What is the transverse fissure in the right lung?

A

separates upper & middle lobe

36
Q

What is the hilum of the right lung?

A
  • connects the lung to bronchi
  • contains pulmonary art. + veins
37
Q

What are the impressions of the right lung from anterior to posterior?

A
  • brachiocephalic vein
  • trachea
  • esophagus
  • arch of Azygos
38
Q

What is the lingula on the left lung?

A
  • on sup. lobe
  • remnant of missing 3rd lobe
39
Q

What are the 2 lobes of the left lung?

A

sup & inf

40
Q

What is the function of the hilum of the left lung?

A
  • connects the lung to the bronchi
  • contains pulmonary art & veins
41
Q

What are the impressions of the left lung from anterior to posterior?

A
  • cardiac notch
  • subclavian art.
  • aorta
42
Q

How do the pulmonary veins of the lungs enter?

A

via hilium

43
Q

What is the arterial supply of the lung? (RALS)

A
  • right pulmonary art. = ant
  • left pulmonary art. = sup
44
Q

What is the bronchopulmonary segment?

A

where bronchi split with own arterial branch to supply a specific lung area

45
Q

What is the flow of bronchis?

A

trachea -> primary bronchi -> secondary bronchi -> tertiary bronchi
