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 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?
What is another way of naming a posterior curve pattern?
A kyphotic curve
What joint classifications are identified at the vertebral body of the typical thoracic?
Fibrous (Amphiarthrosis) Syndesmosis, cartilaginous (Amphiarthrosis) symphysis and synovial plane (diarthrosis arthrodia)
How many synovial joint are formed at the vertebral body of the typical thoracic?
How many symphysis joints are formed with the vertebral body of the typical thoracic?
How many Syndesmosis joints are formed at the vertebral body of a typical thoracic?
Typically four are identified (as many as eight if the costocentral Stellate/radiate ligaments are included)
What is the name given to the joint formed between the vertebral body and rib?
How many costocentral joints are formed at the vertebral body of a typical thoracic?
Which of the Demi facets on the vertebral body of a typical thoracic is larger?
The superior costal Demi-facet
What ligaments support the costocentral joint?
The costocentral stellate/radiate ligament and the costocentral interarticularis 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
Which muscle(s) is attached to the vertebral body of T2 or T3?
The Longus Colli
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?
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 are the osseous parts of the costotransverse joint?
The transverse costal facet and the articular surface of the tubercle of a rib
What ligaments support the costotransverse joint of a typical thoracic?
The superior costotransverse, inferior costotransverse, and lateral costotransverse ligaments
Which muscle may attach to the transverse process of a typical thoracic?
The Longissimus Thoracis, Longissimus Cervicis, Longissimus Capitis, Semispinalis Thoracis, Semispinalis Cervicis, Semispinalis Capitis, multifidis, rotator Longus, rotator brevis, intertransversarii, levator costarum Longus and levator costarum brevis
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 the 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
What is the orientation of the superior articular facet of a typical thoracic?
They face backward, upward, and lateral (BUL)
What is the orientation of the inferior articular facet of a typical thoracic?
They face forward, downward, and medial (ForMed)
How many synovial joints are present at a typical thoracic?
