Flashcards in Day 7 Deck (21):
1

How can you distinguish between a T2-T4 from T5-T8 segment using the articular process?

at T2-T4 the width between the superior articular processes is greater than the width between the inferior articular processes of that vertebra
at T5-T8 the width between the superior articular processes is equal to or the same as the width between the inferior articular processes of that vertebra

2

What is the angulation of the articular facet of a typical thoracic

about ten to twenty degrees from the coronal plane;
sixty degrees from the horizontal plane

3

What is the orientation of the superior articular facet of a typical thoracic

they face backward, upward, and lateral (BUL)

4

What is the orientation of the inferior articular facet of a typical thoracic?

they face forward, downward, and medial (ForMeD)

5

How many synovial joints are present at a typical thoracic?

ten

6

How many synovial joint surfaces for ribs are present on a typical thoracic?

six

7

What is the angulation of the spinous process in the typical thoracic region?

the undersurface of T2-T4 spinous processes will angle up to forty degrees from the horizontal plane
the undersurface of T5-T8

8

What muscles are associated with the five muscle layers of the true back?

layer one consists of the trapezius and latissimus dorsi
layer two consists of the rhomboids and legator scapulae
layer three consists of the serratus posterior
layer four consists of the erector spinae
layer five consists of the transversospinalis

9

How many synovial joints are formed at the vertebral body of T1?

four normally

10

How many symphysis joints are formed with the vertebral body of T1?

two

11

How many syndesmosis joints are formed at the vertebral body of T1?

typically four are identified (as many as eight if the rib articulation is included)

12

What ligament is absent at the costotransverse joint of T1?

the superior costotransverse ligament

13

What ligaments attach to the transverse process of T1?

intertransverse, capsular costotransverse, superior costotransverse, inferior costotransverse and lateral costotransverse

14

How many synovial joints are formed at the vertebral body of T10?

two

15

How many symphysis joints are formed with the vertebral body of T10?

two

16

How many syndesmosis joints are formed at the vertebral body of T10?

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

17

Which synovial joint surface is absent from the vertebral body of T10?

inferior costal demi-facets

18

How many synovial joints are typically present at T10?

eight

19

How many synovial joints surfaces for ribs are typically present on T10?

four

20

Which rib related facet is absent on T10?

the inferior costal demi-facet

21

What is the topographical indication of the spinous process of T10?

the skin often dimples or is depressed
