T Spine Flashcards
T1 and T12 are
transitional
T2-T11 are
typical
Bodies have ______ for articulation with ribs
demifacets
Spinous proceses slope
inferiorly
transverse processes thickened at
ends
Costovertebral joints are
very stable
costovertebral joint ligaments help to
prevent rib head subluxation/dislocation
Superior facets face mostly
posterior and slightly superior
Inferior facets face mostly
anterior and slightly inferior
What type of osteokinematic motion will the orientation of these facets favor?
lateral flexion
T spine has less mobility than
C or L spine
Upper t spine has
Minimal _____
Some _______
flexion/extension
Rotation and lateral flexion
Lower T spine
More _______
Slightly more ______
Less ______
flexion/extension
lateral flexion
rotation
T1,11, and 12 articulate with

vertebral body
Costotransverse Joints
Ribs articulate with
transverse processes T1-10
Costotransverse Joints
