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)
