Primary or secondary curvature
primary
Primary or secondary curvature
Secondary
acts as a buttress to the weight of the head, relieving the stress of post. musculature
Cervical
formed by anterior & posterior arch
Atlas (C1)
Identify the type of vertebrae
Axis (C2)
Identify the type of vertebrae
Thoracic
vertebrae that mainly supports body weight
Lumbar
Identify the landmark & vertebrae

Posterior tubercle - atlas (C1)
muscular attachment for this vertebrae
Anterior tubercle - atlas (C1)
lateral margins of the upper surfaces of C3-C7 projection to form
Unicate processes - cervical
Identify the landmark & vertebrae
Inferior articular processes - cervical
analogous to the superior articulating processes
Lateral masses - atlas (C1)
atypical projection that is the body of this vertebrae
