Thoracic region Flashcards
thoracic segments considered typical
T2-T8 segments
thoracic segments considered atypical
T1, T9-T12
features allowing discrimination b/w T2-T4 and T5-T8 segmental groups
vertebral body, transverse process, articular process and spinous process
the outline of the vertebral body of a typical thoracic from superior view
triangular
on cranial view, what is the outline of the vertebral body for T5-T8 group
left side of vertebral body flattened, right side convex
name given to the left side appearance of the vertebral body of T5-T8
aortic impression
part of the vertebral body most influenced by the aorta @ T5-T8
left side superior and inferior epiphyseal rims
height pattern of the typical thoracic vertebral body
posterior height greater than the anterior height by 1-2mm
height pattern of intervertebral discs in the typical thoracic region
intervertebral discs are rather planar or flat with no apparent height difference between anterior and posterior heights
principal cause of the posterior curve of the thoracic spine
vertebral body height differences
terms of the anterior-posterior curves of the vertebral column, what direction will the thoracic spine face
posterior
another way of naming a posterior curve pattern
kyphotic curve
joint classification ID at the vertebral body of a typical thoracic
fibrous (amphiarthrosis) syndesmosis, cartilaginous (amphiarthorosis) symphysis and synovial plane (diarthrosis arthrodia)
synovial joints formed @ the vertebral body of a typical thoracic
4
of symphysis joints formed with the vertebral body of a typical thoracic
2
of Syndesmosis joints formed at the vertebral body of a typical thoracic
typically 4 ID’ed (as many as 8 if the costocentral stellate/radiate ligaments are included)
name given to the joint formed between the vertebral body and rib
costocentral joint
of costocentral joints formed at the vertebral body of typical thoracic
