Cervical vertebra and grades. N = (neutral) represents the resting position of each vertebra prior to any mobilization. The seven points on the N plot are the seven cervical vertebra, the top is C2. This graph represents the absolute movement of each vertebra when a posterior to anterior (PA) mobilization (grade II or grade III) is applied. Absolute is defined as the change in position of a vertebra from its resting position when a mobilization is applied. The horizontal axis represents the amount of PA motion of each vertebra and vertical axis represents the amount of superior to inferior motion of the vertebra. A negative number represents a flexion moment while a positive number represents an extension moment
