DHUBS 2 Week 2 - Vertebral Column Flashcards
Describe the differences in the facet orientation at each spinal level.
Cervical = sit at around 45 degrees.
Thoracic = More vertical and posterior facing
Lumbar = More sagittal in orientation.
Can you identify atypical characteristics of the Cervical spine?
C1: Posterior Tubercle
C2: Presence of the Dens
C7: a long spinous process
Can you identify atypical characteristics of the Thoracic spine?
T1: complete costal facet, height of vertebral body and spinous process
shape similar to cervical vertebrae
T9-T12; Complete costal facet. Spinous process taking characteristics of
lumbar spine
Can you identify atypical characteristics of the Lumbar spine?
L5: Largest body and transverse processes
What structure travels through the transverse foramen of the cervical spine?
The vertebral artery
What does the vertebral artery supply?
Supplies blood to the brainstem and cerebellum.
What are the basic parts of the intervertebral disc?
Nucleus Pulposus - centre
Annulus Fibrosis - outer rings
