Flashcards in 8/25 Questions Exam 2 Deck (24):
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 attached to the vertebral body of T2 or 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
What is overlap of the lamina called in the typical thoracic region?
What is the outline of 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 thoracics?
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 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?
levator costarum longus
levator costarum brevis
How can you distinguish between a T2-T4 from T5-T8 segment using the articular process?
T2-T4 the width between the superior articular processes is GREATER than the width between the inferior articular processes of that vertebra
T5-T8 the width between the superior articular processes is EQUAL 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?
How many synovial joint surfaces for ribs are present on a typical thoracic?
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 spinous processes
Imbrication will be more pronounced for what region of the thoracics?
Which thoracic has the longest spinous process?
What is the angulation of the spinous process in the typical thoracic region?
the undersurface of T2-T4 spinous processes will angle up to 40 degrees from the horizontal plane
the undersurface of T5-T8 spinous processes will angle up to 60 degrees from the horizontal plane
