(40 cards)
What features will allow discrimination between T2-T4 and T5-T8 segmental groups?
(4)
Vertebral body
Transverse Process
Articular Process
Spinous Process
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 influent by the aorta at T5-T8?
The left side superior and inferior epiphyseal rims
What is the height pattern of a typical thoracic vertebral body?
The posterior height is greater than the anterior height by 1-2 millimeters
What is the height pattern of intervertebral discs in the typical thoracic region?
The intervertebral discs are patter 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?
Kyphotic Curve
What joint classifications are identified at the vertebral body of a typical thoracic?
(3)
Fibrous (amphiarthrosis) Syndesmosis
Cartilaginous (amphiarthrosis) Symphysis
Synovial Plane (diarthrosis arthrodia)
How many synovial joints are formed at the vertebral body of a typical thoracic?
Four
How many symphysis joints are formed with the vertebral body of a thoracic spine?
Two
How many syndesmosis joints are formed at the vertebral body of a typical thoracic?
Typically- FOUR
As many as eight if the cosocentral stellate/radiate ligaments are included
What is the name given to the joint formed between the vertebral body and rib?
Costocentral joint
What is the relationship between the vertebral body surface and the rib head surface in the costocentral joint of a typical thoracic?
The superior costal demi-facet of the vertebral body will joint the inferior articular surface of the head of the rib
The inferior costal demi-facet of the vertebral body will joint with the superior articular surface of the head of the rib
Which of the semi-facets on the vertebral body of a typical thoracic is larger?
The superior costal-demi facet
What ligaments support the cost-central joint?
The costocentral stellate/radiate ligament
The costocentral interarticular or intra-articular ligament
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 disk
What is the size relationship between the articulating surface of the head of the rib and the costal demo-facet surface?
The rib surface is greater than the costal demi-facet surface
Which muscle(s) is attached to the vertebral body of T2-T3?
The 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 laterally
What is the angulation of the pedicle in the typical thoracic region?
Ten to fifteen degrees posterolateral from the sagittal plane
Which X-ray view is used to see into the intervertebral foramen of a typical thoracic?
The lateral view
Which vertebral notch or incisor is said to be prominent?
The inferior vertebral notch or inferior vertebral incisure
What is overlap of the lamina called in the typical thoracic region?
Shingling
