To construct a human cervical spine with bilateral vertebral artery fluid-solid coupling model.Helical CT images under the principle of reverse engineering and meshed in finite element model（FEM） related software were used to establish model. In process modeling body, artery, ligament, intervertebral disc, cartilage endplate large anatomic data cadaver experiments results referenced. From morphology function simulation model real physiological status was tested.The study showed that stress concentration on surface body blood wall result volume flow rate-time curve consistent published literatures. This well clinical phenomenon.The three-dimensional FEM established by introduced method has been effectively verified. The would provide new tool for research biomechanics.
