Which thoracic segments are considered the typical throacics?
T2-T8 segments
What features will allow discrimination between T2-T4 and T5-T8 segmental groups?
the vertebral body, transverse process, articular process, and spinous process
What is the outline of the vertebral body of a typical thoracic from superior view?
triangular
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
What is the name given to the left side appearance of the vertebral body of T5-T8?
the aortic impression
What part of the vertebral body is most influenced by the aorta at T5-T8?
the left side superior and inferior epiphyseal rims
What is the height pattern of the typical thoracic vertebral body?
the posterior height is greater than the anterior height by one to two millimeters
What is the height pattern of intervertebral discs in the typical thoracic region?
the intervertebral discs are rather planar or flat with no apparent height difference between anterior and posterior heights
What is the principal cause of the posterior curve of the thoracic spine?
the vertebral body height differences
In terms of the anterior-posterior curves of the vertebral column, what direction will the thoracic spine face?
posterior
What is another way of naming a posterior curve pattern?
a kyphotic curve
What joint classifications are identified at the vertebral body of a typical thoracic?
fibrous (amphiarthrosis) syndesmosis, cartilaginous (amphiarthrosis) symphysis, and synovial plane (diarthrosis arthrodia)

the superior costal demi-facet
What feature will provide assistance in maintaining the stability of the intervertebral foramen in the typical thoracics?
the costocentral joint or ribs
What ligaments support the costocentral joint?
the costocentral stellate/radiate ligament and the costocentral interarticular or intra-articular ligament
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
What does the costocentral intra-articular or interarticular ligament connect to?
the interarticular or intra-articular crest of the head of the rib and the intervertebral disc
