1

thoracic segments considered typical

T2-T8 segments

2

thoracic segments considered atypical

T1, T9-T12

3

features allowing discrimination b/w T2-T4 and T5-T8 segmental groups

vertebral body, transverse process, articular process and spinous process

4

the outline of the vertebral body of a typical thoracic from superior view

triangular

5

on cranial view, what is the outline of the vertebral body for T5-T8 group

left side of vertebral body flattened, right side convex

6

name given to the left side appearance of the vertebral body of T5-T8

aortic impression

7

part of the vertebral body most influenced by the aorta @ T5-T8

left side superior and inferior epiphyseal rims

8

height pattern of the typical thoracic vertebral body

posterior height greater than the anterior height by 1-2mm

9

height pattern of intervertebral discs in the typical thoracic region

intervertebral discs are rather planar or flat with no apparent height difference between anterior and posterior heights

10

principal cause of the posterior curve of the thoracic spine

vertebral body height differences

11

terms of the anterior-posterior curves of the vertebral column, what direction will the thoracic spine face

posterior

12

another way of naming a posterior curve pattern

kyphotic curve

13

joint classification ID at the vertebral body of a typical thoracic

fibrous (amphiarthrosis) syndesmosis, cartilaginous (amphiarthorosis) symphysis and synovial plane (diarthrosis arthrodia)

14

# synovial joints formed @ the vertebral body of a typical thoracic

4

15

# of symphysis joints formed with the vertebral body of a typical thoracic

2

16

# of Syndesmosis joints formed at the vertebral body of a typical thoracic

typically 4 ID'ed (as many as 8 if the costocentral stellate/radiate ligaments are included)

17

name given to the joint formed between the vertebral body and rib

costocentral joint

18

# of costocentral joints formed at the vertebral body of typical thoracic

4

19

which demi-facets on the vertebral body of a typical thoracic is larger

superior costal demi-facet

20

what feature will provide assistance in maintaining the stability of the intervertebral foramen in the typical thoracics

costocentral joint or ribs

21

ligaments that support costocentral joint

costocentral stellate/radiate ligament and the costocentral interarticular or intra-articular ligament

22

costocentral stellate/radiate ligament will attach to which segments at the T3 spinal nerve intervertebral foramen

vertebral body of T3 and the vertebral body of T4

23

what does the costocentral intra-articular ligament connect to

interarticular or intra-articular crest of the head of the rib and the intervertebral disc

24

size relationship between the articulating surface of the head of the rib and the costal demo-facet surface

the rib surface is greater than the costal demo-facet surface

25

muscle(s) attached to the vertebral body of T2 or T3

longus colli

26

position and direction of the pedicle from the typical thoracic vertebral body

pedicle arises from the upper third of the vertebral body and projects posterior and slightly lateral

27

angulation of the pedicle in the typical thoracic region

10-15* posterolateral from the sagittal plane

28

X-ray view used to see into the intervertebral foramen of a typical thoracic

lateral view

29

overlap of the lamina in the typical thoracic region is called

shingling

30

outline of the vertebral foramen in the typical thoracic region

oval to circular
