illiolumbar arteries
Medial and lateral sacral arteries
curvatures are present at birth and (concave/convex) posteriorly
Primary
Convex
Examples of primary curvatures
thoracic and sacral
Primary curvature exaggeration: ______
Kyphosis
Secondary curvature exaggeration: ______
Lordosis
Secondary curvature is (concave/convex) posteriorly
concave
What are the two joints of the vertebral column?
Disc Symphsis and Synovial
Examples of secondary curvature
Cervical and Lumbar
What is distinct of a cervical vertebra?
oblique facets
“holes” or transverse forminae for vertebral arteries
What is distinct of a thoracic vertebra?
Centrum or body is heart shaped
Articular facets are more horizontal
Spinous process is longer and narrower
Has rib articulations
What is distinct of a lumbar vertebra?
Large, bulky centrum
Broad spinous process
No rib articulations
Articular facets saggital
Anterior Longitudinal ligament
limits extension
Reinforces anterior annulus fibers
Posterior longitudinal ligament
Limits flexion
Reinforces posterior annulus fibers
Supra-spinous
Aka Ligamentum Nuchae
Inter-spinous
Limits flexion
Base of one spinous process to next spinous process
Ligamentum flavum
limits flexion
extends from lamina to lamina
Forms part of roof of vertebral canal
