Thoracic Region: T2-T8 Flashcards
What features will allow discrimination between T2-T4 and T5-T8 segmental groups?
The vertebral body, transverse process, articular process and spinous process
What part of the vertebral body is most influenced by the aorta at T5-T8?
The left side superior and inferior epiphyseal rims
What synovial joint surfaces are present on the vertebral body of a typical thoracic?
The right and left superior and the right and left inferior costal demi-facets
which demi-facets on the vertebral body of a typical thoracic is larger?
The superior costal demi facet
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 lateral
What is the appearance and position of the lamina in a typical thoracic?
the lamina is short, broad and thick and lies next to the spinous process?
What is the direction of the transverse process of the typical thoracics?
The transverse process projects more posteriorly with each inferior vertebra
How did the transverse diameters of the articular process compare int eh T2-T4 region?
The superior articular process transverse diameter is greater than the inferior articular process transverse diameter for a given segment
How to the transverse diameters of the articular process compare to the T5-T8 segments?
The superior articular process transverse diameter is the same as or equal to the inferior articular process transverse diameter for a given segment
What is the angulation of the spinous process of T2-T4?
The undersurface of T2-T4 spinous process will angle up to forty degrees from the horizontal plane
What is the angulation of the spinous process of T5-T8?
The undersurface of T5-T8 spinous process will angle up to 60 degrees from the horizontal plane
