What are 4 characteristics of rib angle?

1) posteriolateral aspect
2) lateral to spinous process
3) illiocostalis muscle attachments
4) key landmark for rib dysfunction -tender / soft tissue restrictions

62

The superior facet articulates with. V. body above:

T6

63

Inferior facet articulates with superior facet of v. body below

T7
* articulation occurs at the ribs own numbered vertebrae- Rib 7

64

Atypical thoracic rib articulations include:

-T1 and T10-T12 and ribs 1, 10-12

65

T1 is full costal face superiorly that accepts the entire head of the ______ rib. Demifacet inferiorly to accept part of the head of the ______ rib.

1st
2nd

66

T10-12 may have full:

costal facet (pedicles)

67

T11-12 typically lack _______________ joints

costotransverse joints

68

Kinematics or the ribs: upper 1-6 =

motion occurs in the sagittal plane

69

Kinematics or the upper ribs: During inspiration, upper ribs and sternum increase the AP diameter =

pump-handle motion

70

Kinematics or the ribs: lower 7-12 =

frontal plane

71

Kinematics or the lower ribs: During inspiration, lower ribs increase the transverse diameter =

bucket-handle motion

72

What are the 3 parts of the diaphragm?

1) costal part
2) sternal part
3) crural part

73

The costal part of the diaphragm =

upper margins of the lower 6 ribs

74

The sternal part of the diaphragm =

posterior side of the xiphoid process

75

The crural part of the diaphragm =

attached to the bodies of the upper 3 lumbar vertebrae - R & L crus

76

Action of the diaphragm during inspiration is caused by the ________ nerve.

phrenic

77

What is the most important muscle of the inspiration?

diaphragm

78

As the dome (of the diaphragm) lowers and flattens:

increases the vertical diameter of the thorax
** inhale = pressure decreases

79

As the diaphragm descends, the central tendon moves _________ and becomes _________.

inferiorly
static

80

The diaphragm continues to contract resulting in lower 6 ribs __________ and rotate ________.

elevate
postseriorly
**interabdominal pressure increases

81

__________ intrathoracic volume __________ intrathoracic pressure, and __________ abdominal pressure

Increase in
decreases
increases

82

Quiet expiration is _______ process. Elastic recoil of the ________, ________ and __________

passive
thorax, lungs and diaphragm

83

Forced expiration =

activation of abdominals and intercostals

84

What are the primary muscles of inspiration?

diaphragm, intercostals, scalene muscles

85

What muscles are active during forced inspiration?

-serratus posterior
-sternocleoidmastoid
-lattismus dorsi
-iliocostalis thoracis
-pectoralis muscles
-quadratus lumborum

86

Expiratory muscles include:

-4 abdominal muscles
- Internal intercostals
-Transverse thoracis

87

During forward bending (flexion) of the ribs the osteokinematics include _________ rotation of T3-T7. Arthrokinematics include ___________ glide and _________ roll.

anterior
superior
anterior

88

During backward bending (extension) of the ribs the osteokinematics include _________ rotation of T3-T7. Arthrokinematics include ___________ glide and _________ roll.

posterior
inferior
posterior
