24
Q

internal intercostals

A

superiomedially
perpendicular to external
expiration

innermost is the same

25
Q

transversus thoracis

A

along the sternum and costal cartilage
attach the rib body
depress the rib in expiration

26
Q

subclavius

A

aid the clavicle to lift inferiorly

27
Q

order and location of the neuromuscular bundle

A

in the costal groove between the internal and innermost intercostals
vein, artery, nerve

28
Q

why won’t you see a single rib in a cross section

A

as they slope down
so will see a few intermittent ribs

29
Q

categories of ribs

A

true
false
floating

30
Q

true ribs

A

directly attach the costal cartilage to the sternum
1-7

31
Q

false ribs

A

indirectly attach the costal cartilage to the sternum
fused with costal cartilage of other ribs
8-10

32
Q

floating ribs

A

aren’t connected to the sternum
ribs 11 and 12

33
Q

types of vertebrae

A

cervical
thoracic
lumbar

34
Q

what do cervical vertebrae look like

A

elephants

35
Q

what do thoracic vertebrae look like

A

a giraffe
they have demifacets for rib articulation

36
Q

what do lumbar vertebrae look like

A

moose
cow
rhino

37
Q

why is the sternal angle used as a landmark k

A

as the second rib can be located laterally
count the ribs in order to correctly intubate

38
Q

how does the rib anteriorly articulate

A

via costal cartilage

39
Q

how does the rib posteriorly articulate

A

head with the body of the vertebrae and the transverse process
2 facets

40
Q

muscles involved in the chest wall

A

pectorals major, anterior= clavicle (bone) and medially= sternum (bone), fibres travel inferiorly, laterally and superiorlaterally, converge at the humerus

pectoralis minor: scapula and thoracic cage
external abdominal oblique
latissimus dorsi
serratus anterior

41
Q

accessory muscles of expiration

A

sternocleidomastoid
serratus anterior
scalene

42
Q

accessory muscles of inspiration

A

abdominals
recti obliques
transverse abdominus

43
Q

what does phrenic relate to

A

the diaphragm

44
