Day 7 Flashcards
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 that 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 angulation of the articular facet of a typical thoracic
about ten to twenty degrees from the coronal plane;
sixty degrees from the horizontal plane
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?
ten
How many synovial joint surfaces for ribs are present on a typical thoracic?
six
What is the angulation of the spinous process in the typical thoracic region?
the undersurface of T2-T4 spinous processes will angle up to forty degrees from the horizontal plane
the undersurface of T5-T8
What muscles are associated with the five muscle layers of the true back?
layer one consists of the trapezius and latissimus dorsi
layer two consists of the rhomboids and legator scapulae
layer three consists of the serratus posterior
layer four consists of the erector spinae
layer five consists of the transversospinalis
How many synovial joints are formed at the vertebral body of T1?
four normally
How many symphysis joints are formed with the vertebral body of T1?
two
How many syndesmosis joints are formed at the vertebral body of T1?
typically four are identified (as many as eight if the rib articulation is included)
What ligament is absent at the costotransverse joint of T1?
the superior costotransverse ligament
What ligaments attach to the transverse process of T1?
intertransverse, capsular costotransverse, superior costotransverse, inferior costotransverse and lateral costotransverse
How many synovial joints are formed at the vertebral body of T10?
two
How many symphysis joints are formed with the vertebral body of T10?
two
