1

T1-3 rule of 3's?

SP is located at level of corresponding TP

2

T4-6 rule of 3's?

SP is located one-half a sefment below the corresponding TP

3

T7-9 rule of 3's?

SP is located at level of TP of vertebrae below

4

Follows same rules as T7-9?

T10

5

Follows same rules as T5-7?

T11

6

Follows same rules as T1-3?

T12

7

Spine of scapula is at what level?

T3

8

Inferior angle of scapula corresponds with what?

Spinous process of T7

9

Sternal notch is at what level?

T2

10

Sternal angle (angle of Louis) attaches to which rib and what level is it?

2nd rib, level of T4

11

What is the main motion of the thoracic spine?

Rotation

12

Upper and middle thoracic spine motion?

Rotation > flexion/extension > SB

13

Lower thoracic spine motion?

Flexion/extension > SB > rotation

14

Primary muscles of respiration?

Diaphragm, intercostals

15

Rib attachments for diaphragm?

Ribs 6-12 b/l

16

Vertebral attachments for diaphragm?

L1-3

17

Anterior attachment for diaphragm?

Xiphoid

18

Action of intercostal muscles?

Elevate ribs during inspiration and prevent retractions during inspiration

19

Secondary muscles of respiration?

Scalenes, pec minor, serratus anterior/posteiror, quadratus lumborum, latissimus dorsi

20

What makes a typical rib typical?

Contains Shaft, Head, Angle, Neck, Tubercle (SHANT)

21

What is the difference bt head and tubercle of rib?

Head--articulates with vertebra above and corresponding vertebra; tubercule--articulates with corresponding TP

22

Typical ribs?

3-10

23

Atypical ribs?

1, 2, 11, 12 (ribs with "1" and "2"), sometimes 10

24

Reason why rib 1 is atypical?

Articulates only with T1 and has no angle

25

Reason why rib 2 is atypical?

Has large tuberosity on shaft for serratus anterior

26

Reason why ribs 11 and 12 are atypical?

They articulate only with corresponding vertebrae and lack tubercles

27

Reason why rib 10 may be atypical?

May articulate only with T10

28

True ribs?

1-7 (attach to sternum thru costal cartilages)

29

False ribs?

8-12 (connected by its costal cartilage to the cartilage of the rib superior)

30

Floating ribs?

11, 12

31

Rib motions?

Pump handle, bucket handle, caliper

32

Move primarily in pump handle?

Ribs 1-5

33

Move primarily in bucket handle?

Ribs 6-10

34

Move primarily in caliper?

Ribs 11 and 12

35

Rib appears to be "held up", will not move caudad?

Inhalation dysfunction

36

Rib appears "held down", will not move cephalad?

Exhalation dysfunction

37

Rib elevated anteriorly?

Pump handle inhalation dysfunction (depressed anteriorly for exhalation dysfunction)

38

Rib elevated laterally?

Bucket handle inhalation dysfunction (depressed laterally for exhalation dysfunction)

39

Anterior narrowing of intercostal space above dysfunctional rib?

Pump handle inhalation dysfunction (opposite for exhalation dysfunction)

40

Lateral narrowing of intercostal space above dysfunctional rib?

Bucket handle inhalation dysfunction (opposite for exhalation dysfunction)

41

Superior edge of posterior rib angle is prominent?

Pump handle inhalation dysfunction (opposite for exhalation dysfunction)

42

Lower edge of rib shaft is prominent?

Bucket handle inhalation dysfunction

43

What is the key rib responsible for group inhalation dysfunctions?

Lowest rib

44

What is the key rib responsible for group exhalation dysfunction?

Uppermost rib

45

Where is tx directed for a group dysfunction?

Key rib
