2nd rib, level of T4

11
Q

What is the main motion of the thoracic spine?

A

Rotation

12
Q

Upper and middle thoracic spine motion?

A

Rotation > flexion/extension > SB

13
Q

Lower thoracic spine motion?

A

Flexion/extension > SB > rotation

14
Q

Primary muscles of respiration?

A

Diaphragm, intercostals

15

Ribs 6-12 b/l

16
Q

Vertebral attachments for diaphragm?

A

L1-3

17
Q

Anterior attachment for diaphragm?

A

Xiphoid

18
Q

Action of intercostal muscles?

A

Elevate ribs during inspiration and prevent retractions during inspiration

19
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

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
