1

What is the shape of the body of T4

Heart shaped

2

The left sides of the upper 4-Tspine are flattened for ____

The aorta

3

What is generally the stiffest segments of the spine?

T1-T6

4

Are pedicles in the L-Spine different then T-Spine?

The pedicles in the T-spine face more posterior

5

What is different about the lamina in the T-Spine vs. the L-Spine?

They are wider and overlap

6

What's the importance of the inferior and superior articulating process?

They determine movement based on the orientation of the facets

7

What is the orientation of the facets in the T-Spine?

Superior = posterior and lateral
Inferior = anterior and medial

8

What movement is facilitated or guided by the orientation of the facets in the T-spine?

Side bending and rotation

9

What restricts side bending and rotation at the T-Spine?

Ribs

10

What is different about the SP's in the thoracic region?

Longer
Thinner – less muscle attachment and/or muscle aren't create as much force as in the lumbar spine
Pointing inferiorly – so much so in the lower portion that they begin to overlap

11

Why is the fact that the SP's in the t-spine overlap important for palpation purposes?

They will be found below the level of the vertebral body, so won't be placed where you think they are
Also the space between the SP's is extremely small

12

What is important about the tp's in the t-spine?

-still stout and thick because they articulate with the ribs
-ribs attach on the anterior aspect of the TP

13

How many regions is the t-spine broken into

3

14

what do the ribs articulate with in the t-spine

vertebral body
disc
anterior aspect of TP's

15

If you have a vertebrae in disfunction what can this cause with regard to breathing?

a vertebrae in disfunction will ALWAYS cause a rib disfunction, which will negatively impact your breathing

16

if you have a rib injury what would you also what to treat

the thoracic vertebrae that the rib corresponds with

17

what happens to the vertebrae of the t-spine as you go lower down, specifically with regard to SP's

they are no longer overlapping and are a lot like the lumbar spine at this point

18

What is different between T1 and T2 with respect to the rib articulation?

The rib at that level articulates with one full rib and a bit of rib 2

19

Thoracic vertebrae of T1 is an ___ vertebrae

atypical

20

A typical vertebrae has articulation with part of _ ribs

2

21

Rib 1 articulates solely with ____

T1

22

If the rib does not articulate with the TP, it is _____

free floating

23

What ribs in the t-spine have the most mobility

9-12
9-10 variable
11-12 on everybody

24

Where do you get the most rotation in the T-spine and why?

-Lower t-spine due to the fact the ribs are not articulating with the TP's
-Ribs restrict side bending and rotation and because they do not attach in the lower t-spine you get more rotation through this area

25

What movement is restricted in the lumbar spine because of the orientation of the facets?

Rotation

26

If you get a person to rotate where should you see most of the movement occurring?

Lower t-spine

27

If you have restriction through T9-T12 what could this cause?

If you don’t get rotation during normal walking then you are going to get more stress on the SI joint and hips. Therefore restriction at 9-12 can cause huge complications elsewhere

28

The head of the rib articulates with the.....

posterior aspect of the vertebral body, a larger facet on the superior aspect and a smaller facet on the inferior portion of the body along with the intervertebral disc

29

What is a consequence of the head of the rib articulating right into the vertebral disc in the t-spine?

Decrease mobility of the disc

30

T2-T8 have a _______ body with the transverse and anteroposterior dimensions being almost _____

T2-8 have a cylindrical body with the transverse and anteroposterior dimensions being almost equal
