Q

Which intermediate posterior muscle plays a principle role in respiration?

A

Pec major and minor
Deltoid
Serratus anterior

21
Q

Which joint is also known as the Angle of Louis?

A

Sternomanubrial Joint

Sternal angle - rib 2

22
Q 
\_\_\_\_\_\_\_\_\_\_\_\_\_\_ is the angle between the 12th rib and
lumbar vertebae (location of Murphy’s punch sign for perinephritic abscess)
A

Costovertebral angle

23
Q

Where does the superior border of the scapula correspond to?

24
Q

Where does the root of the scapular spine correspond to?

25
Where does the inferior border of the scapula correspond to?
T7
26
Where are pump handle motions most prominent?
Upper costal segments
27
Where are bucket handle motions most prominent?
Mid/lower costal segments
28
Wait, but if it isn't bucket handle or pump handle motion, what is happening at ribs 11 and 12?!
Caliper
29
Torsional motion (internal/external) occurs in all costal segments however is most dominant in the ...
mid/lower ribs
30
Ribs follow a (convex/ concave) rule
Convex
31
When you go into thoracic flexion, you have an over all ________ torsion of the ribs.
Internal
32
Bony architecture plays a larger role in rib motions during (flexion/ extension)
Extension
33
The normal response of the ribs to thoracic extension is ...
External torsion
34
When i rotate to the left, the rib on the right will go into _________ torsion and the rib on the left will go into _________ torsion.
Rotate left Right rib- internal torsion Left rib- external torsion
35
When I side bend to the right, my right rib goes into _______ torsion while my left rib goes into________.
Side bend right Right rib- internal Left rib- external
36
A dysfunctional key rib during inhalation is the (top/ bottom) rib, and during exhalation is the (top/ bottom) rib that is stuck in place.
Inhalation- top | Exhalation- bottom
37
As you progress down the spine, rib angles grow more ...
Lateral
38
What is the mechanism or injury for superior first rib subluxation? What are its symptoms?
``` Mechanism of Injury: Traumatic lateral neck flexion • 5-6 mm higher • Marked tenderness • Diminished depression upon exhalation • Scalene hypertonicity ```
39
What is the mechanism or injury for anterior rib subluxation? What are its symptoms?
Mechanism of Injury: Traumatic force to posterior rib angle * More prominent anteriorly * Less prominent rib angle * Tender iliocostalis muscle * Limits inhalation/exhalation
40
What is the mechanism or injury for posterior rib subluxation? What are its symptoms?
Mechanism of Injury: Traumatic force to anterior extremity of the rib * More prominent Rib Angle * Less prominent anteriorly * Tender iliocostalis muscle * Limits inhalation/exhalation
41
What is the mechanism or injury for anterior-posterior rib compression? What are its symptoms?
Mechanism of Injury: Traumatic A-P compression of the costal cage * Mid-axillary line prominence * Diminished A/P prominence * Tender iliocostalis muscle * Limits inhalation/exhalation
42
What is the mechanism or injury for lateral rib compression? What are its symptoms?
Mechanism of Injury: Traumatic lateral compression of the costal cage ``` • Diminished mid-axillary line prominence • A/P prominence • Tender iliocostalis muscle • Limits inhalation/exhalation ```
43
What is the mechanism or injury for internal rib torsion? What are its symptoms?
Mechanism of Injury: Combined flexion/rotation injury (FRS) * Inferior border more prominent posteriorly * Superior border less prominent posteriorly * Tender iliocostalis muscle * Limits primarily inhalation
44
What is the mechanism or injury for external rib torsion? What are its symptoms?
Mechanism of Injury: Combined extension/rotation injury (ERS) ``` • Superior border more prominent posteriorly • Inferior border less prominent posteriorly • Tender iliocostalis muscle • Limits primarily exhalation ```
45
What is the mechanism or injury for a laterally flexed rib? What are its symptoms?
Mechanism of Injury: Traumatic lateral trunk flexion * Mid-axillary prominence of rib shaft * Intercostal space asymmetry above/below rib shaft * Tender iliocostalis muscle * Limits primarily exhalation
