Q

What muscle directly overlays the ribcage/ what muscles lie inbetween the ribs?

A

Serratus anterior = just anterior to ribcage

External intercostal, internal intercostal, innermost intercostal muscles = between ribs

Q

How do you find the oblique fissure?

A

put their hand on their head and find spine of scapula - go medial to the spine = T4

Then, if you follow the 6th rib from there around the thorax to the sternum = the oblique fissure

Q

How do you find the horizontal fissure of the lung?

A

it arises at the 4th costal cartilage and moves laterally to meet the oblique fissure at the mid-axillary line

Q

Describe the plura surrounding the lungs

A

two types of plura - fibrous externally and serous internally

Serous pleura divided into the parietal and visceral pleura with potential space inbetween

Q

where does the pleura extend from?

A

parietal pleura goes up behind your clavicle ( which is why your clavicle is resonant)

pleura extends down to the 12th rib (about an inch above your pelvis)

Q

On surface anatomy, how do you determine where the pleura is and where the lungs are?

A

From Mid Clavicle, mid axillary, mid scapular lines…

pleura = 8th, 10th and 12th rib

lung = 6th, 8th, 10th rib (always about two inches above pleura

Q

What segment of the lung is vulnerable to collapse in cystic fibrosis?

A

bronchopulmonary segment - area of the lung supplied by a segmental bronchus and branch of pulmonary artery - share tributaries of pulmonary vein and lymphatics

17
Q

What are the bronchopulmonary segments on the right lung?

A

“A PALM AM ALP”

  • apical - posterior - anterior - lateral - medial - apical(superior basal) - medial basal - anterior basal - lateral basal - posterior basal
18
Q

What muscles are accesory on inspiration?

A

external intercostal and pec major

19
Q

what muscles are excessory for exhalation?

A

internal intercostals

20
Q

what are the two layers of plura?

A

parietal/visceral

21
Q

how far inferiorly can you find the plura?

A

plura goes = 8,10,12th ribs from mid clavicle, mid axila, mid scapular respectively

lung goes = 6,8,10th ribs from mid clavicle, mid axila, mid scapular respectively

22
Q

what cuases a pneumothorax?

A

a puncture through the parietal plura (lots of negative pressure that sucks air in and collapses the lung)

23
Q

At what vertebral level can we find the oblique fissure?

A

T4 follow down the 6th rib to the sternum

24
Q

how many lobes does the right and left lung have?

A

right lung = 3 (horizontal fissure at CC4)

left lung = 2

25
Q

where can you find the horizontal fissure?

A

C4 over to mid axillary line

26
Q

describe the strucutres you would find at the root of the righ and left lung?

A
27
Q

what is the ‘root’ of hte lung called?

A

hilum

28
Q

at what level does the trachea bifurcate?

A

T4

29
Q

how many bronchopulmonary segments are on the right/left lungs?

A

10 on right

less than 10 on left

30
Q

what are the right sided pulmonary segments?

A

APALM APALM

upper = apical, posterior, anterior

middle = lateral, medial,

lower= apical basilar, posterior balisar, anterior basilar, lateral basilar, medial basilar
