Flashcards in Typical Thoracic Vertebrae (T2-T8) Deck (37):
1

What features will allow discrimination between T2-T4 and T5-T8 segmental groups

the vertebral body, transverse process, articular process and spinous process

2

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

triangular

3

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

the left side of the vertebral body will be flattened, the right side convex

4

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

the aortic impression

5

What part of the vertebral body is most influenced by the aorta at T5-T8

the left side superior and inferior epiphyseal rims

6

What is the height pattern of the typical thoracic vertebral body

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

7

What is the principal cause of the posterior curve of the thoracic spine

the vertebral body height differences

8

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

posterior

9

What is another way of naming a posterior curve

a kyphotic curve

10

What joint classifications are identified at the vertebral body of a typical thoracic

fibrous (amphiarthrosis) syndesmosis
cartilaginous (amphiarthrosis) symphysis
synovial plane (diarthrosis arthrodia)

4

12

how many symphysis joints are formed with the vertebral body of a typical thoracic

2

13

how many syndesmosis joints are formed at the vertebral body of a typical thorcic

typically four are identified (as many as 8 if the costocentral stellate/radiate ligaments are included)

14

how many joints are formed at the vertebral body of a typical thoracic

typically ten ( fourteen if you include the costocentral stellate/radiate ligaments)

15

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

costocentral joint

16

how many costocentral joints are formed at the vertebral body of a typical thoracic

4

17

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

the superior costal demi-facet

18

What ligaments support the costocentral joint

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

19

the costocentral stellate/radiate ligament will attach to which segment(s) at the T3 spinal nerve intervertebral foramen

the vertebral body of T3 and the vertebral body of T4

oval to circular

24

in which plane will the size of the vertebral foramen of a typical thoracic be the greatest

the transverse plane, the vertebral transverse diameter

25

What are the osseous parts of the costotransverse joint

the transverse costal facet and the articular surface of the tubercle of a rib

26
