What does the cost essential intraarticular or inter articular ligament connect to
The inter-articular or intra-articular crest of the head of the rib and the intravertebral disc
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 cost of Demi facet surface
Which muscle is attached to the vertebral body of T2 or T3
Longus colli
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 lateral
What is the angulation of the pedicle in the typical thoracic region
10 to 15° posterior lateral from the sagittal plane
Which x-ray view is used to see into the intervertebral foramen of a typical thoracic
The lateral view
What is overlap of the lamina called in the typical thoracic region
Shingling
Which the thoracic segments are considered the typical for thoracics
T2-T8
What is the outline of the vertebral foramen in the typical thoracic region
Oval to circular
In which plane will the size of the vertebral foramen of a typical thoracic be greatest
The transverse plane the vertebral transverse diameter
What is the direction of the transverse process in the typical thoracic’s
The transverse process projects more posterior with each inferior vertebra
What is present at the tip of the transverse process of a typical thoracic
The transverse tubercle
What are the osseous parts of the costotransverse joint
The transverse costal facets in the articular surface of the tubercle of a rib
What ligaments support the costotransverse joint of a typical thoracic
The superior costotransverse
inferior costotransverse
lateral costotransverse

10
How many synovial joints surfaces for ribs are orient on a typical thoracic
6
Identify the synovial joint surfaces for ribs that are present on a typical thoracic
Two superior costal Demi facets
Two inferior costal Demi facets
Two transverse costal facets
What is imbrication
The overlap of the spinous process
Imbrication will be more pronounced for what region of thoracics
T5-T8
Which thoracic has the longest spinous process
T8
What is the angulation of the spinous process in the typical thoracic region
The undersurface of T2-T4 spinous process will angle up to forty degrees from the horizontal plane
The undersurface of T5-T8 spinous process will angle up to sixty degrees from the horizontal plane
How can you distinguish between T2 through T5 word from T5 through T8 segment using the articular process
At T2-T4 for 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 inferior articular processes of that vertebra
