Building anatomical coordinate systems. a. Reconstructed left lateral view of the skull and neck with C10 boxed. b-d. Dorsolateral views of C10. b. Cranial (top) and caudal (bottom) views of C10 with purple spheres marking the points used to build the horizontal and axial vectors. c. Views as in b. of C10 with anatomical coordinate systems in place. d. Cranial view of C10 with anatomical coordinate systems made more visible
