5

Vertebrae are built for ____ not _____

mobility; stability

6

How do we achieve more stability in the cervical spine?

Muscles provide additional stability; muscle sprains more likely in MVA

7

Facet angle

45 degrees anterior and superior

8

Why are cervical transverse processes predisposed to fx?

Thinness of bridge to transverse process

9

Orientation of cervical transverse process

Anterolateral

10

Uncinate process

Not present at birth
Develops @ 5-10 years
Limits sidebending
Guides flx/ext

11

What compromises bloodflow to head?

Rotation/sidebending
Extension & Rotation: bilateral decrease more on contralateral side

C1 superior facet shape

Concave

13

C1 inferior facet shape

Convex
