How many synovial joints are formed at the vertebral body of a typical thoracic?
Four
What joint classifications are identified at the vertebral body of a typical thoracic?
Fibrous (amphiarthrosis) syndesmosis, cartilaginous (amphiarthrosis) symphysis and synovial plane (diarthrosis arthrodia)
How many symphysis joints are formed with the vertebral body of a typical thoracic?
Two
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)
How many joints are formed at the vertebral body of a typical thoracic?
Typically ten (fourteen if the costocentral 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 with the inferior articular surface of the head of the rib
The inferior coastal demi-facet of he vertebral body will joint with the superior articular surface of the head of the rib.
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 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 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 costal demi-facet surface
Which muscle(s) is sttached to the vertebral body of T2 or T3?
The longus colli
What it the position mad direction of the pedicle from the typical thoracic vertebral body?
The pedicle arises from the upper third of the vertebral body mad 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 ivf of a typical thoracic?
The lateral view
Which vertebral notch or incisure is said to be prominent?
The inferior vertebral notch or inferior veterbral incisure
What is overlap of the lamina called in the typical thoracic region?
Shingling
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 present on the transverse tubercle of a typical thoracic?
the transverse costal facet
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 muscles may attach to the transverse process of a typical thoracic?
the longissimus thoracis, longissimus cervicis, longissimus capitis
semispinalis thoracics, semispinalis cervicis, longismuss capitis
multifidis, rotator longus, rotator brevis, intertransversarii, , levator costarum longus and levator costarum brevis
