Name the line of mensuration and explain what a normal finding:

Atlantoaxial alignment Normal: The lateral margins of the atlas lateral masses are compared to the opposing lateral corner of the axis articular surface should be in vertical alignment.
Name the line of mensuration and explain what a normal finding:

Cervical gravity line Normal: A vertical line is drawn through the apex of the odontoid process should pass through the C7 body

Cervical lordosis i.e. Angle of the cervical curve Minimum: 35deg Maximum: 45deg
Name the line of mensuration and explain what a normal finding:

Stress lines of the cervical spine Normal Flexion: These lines normally should intersect at the level of the C5-C6 disc or facet joints Normal Extension: These lines normally should intersect at the level of the C4-C5 disc or facet joints
