Q

Secondary muscles of respiration?

A

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

20
Q

What makes a typical rib typical?

A

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

21
Q

What is the difference bt head and tubercle of rib?

A

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

22
Q

Typical ribs?

A

3-10

23
Q

Atypical ribs?

A

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

24
Q

Reason why rib 1 is atypical?

A

Articulates only with T1 and has no angle

25
Q

Reason why rib 2 is atypical?

A

Has large tuberosity on shaft for serratus anterior

26
Q

Reason why ribs 11 and 12 are atypical?

A

They articulate only with corresponding vertebrae and lack tubercles

27
Q

Reason why rib 10 may be atypical?

A

May articulate only with T10

28
Q

True ribs?

A

1-7 (attach to sternum thru costal cartilages)

29
Q

False ribs?

A

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

30
Q

Floating ribs?

A

11, 12

31

33
Q

Move primarily in bucket handle?

A

Ribs 6-10

34
Q

Move primarily in caliper?

A

Ribs 11 and 12

35
Q

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

A

37
Q

Rib elevated anteriorly?

A

Pump handle inhalation dysfunction (depressed anteriorly for exhalation dysfunction)

38
Q

Rib elevated laterally?

A

Bucket handle inhalation dysfunction (depressed laterally for exhalation dysfunction)

39
Q

Anterior narrowing of intercostal space above dysfunctional rib?

A

Pump handle inhalation dysfunction (opposite for exhalation dysfunction)

40
Q

Lateral narrowing of intercostal space above dysfunctional rib?

A

Bucket handle inhalation dysfunction (opposite for exhalation dysfunction)

41
Q

Superior edge of posterior rib angle is prominent?

A

Pump handle inhalation dysfunction (opposite for exhalation dysfunction)

42
Q

Lower edge of rib shaft is prominent?

A

Bucket handle inhalation dysfunction

43

A

Lowest rib

44
Q

What is the key rib responsible for group exhalation dysfunction?

A

Uppermost rib

45
Q

Where is tx directed for a group dysfunction?
