Flashcards in 8/25 Questions Exam 2 Deck (24):
1

What is the size relationship between the articulating surface of the head of the rib and the costal demi-facet surface?

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

2

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

the longus colli

3

What is the position and direction of the pedicle from the typical thoracic vertebral body?

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

4

What is the angulation of the pedicle in the typical thoracic region?

ten to fifteen degrees posterolateral from the sagittal plane

5

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

the lateral view

6

What is overlap of the lamina called in the typical thoracic region?

shingling

7

What is the outline of vertebral foramen in the typical thoracic region?

oval to circular

8

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

the transverse plane, the vertebral transverse diameter

9

What is the direction of the transverse process in the typical thoracics?

the transverse process projects more posterior with each inferior vertebra

10

What is present at the tip of the transverse process of a typical thoracic?

the transverse tubercle

11

What are the osseous parts of the costotransverse joint?

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

12

What ligaments support the costotransverse joint of a typical thoracic?

the superior costotransverse, inferior costotransverse, and lateral costotransverse ligaments
