Measurements are influenced by shear and transverse compression. Centrum length includes condyle length. Neural arch height is measured from the dorsal margin of the cotyle rim vertically to an horizontal line joining both posterior margins of the postzygapophyses. Neural spine height is measured vertically from the dorsal margin of the cotyle rim to the neural spine tip.
