Physical neck model suitable for all neck injuries and particularly the "whiplash" neck injuries comprising a number of connection interface components that enables installation of the neck model to the crash test dummy said neck model further comprising: • five intervertebral discs that are positioned between the vertebra 3 and the vertebra 7, the intervertebral discs and eight types of ligaments (13-20 and 26) that connect the vertebrae with each other where internal structure of the capsular ligaments connective tissue forms the facet joints wherein; ∘ connective tissue is positioned to provide connection between the front bottom-top surfaces of the C1 and C2 vertebrae ∘ connective tissue is positioned to provide connection between the bottom-top surfaces of the right and left parts of the consecutive vertebrae in all the C1 - C7 vertebrae. ∘ connective tissue is positioned to provide connection between the rear bottom-top surfaces of the C1 and C2 vertebrae. ∘ connective tissue is positioned to provide connection between the front inner surfaces of the C1 and C2 vertebrae. ∘ connective tissue is positioned to provide connection between the front surfaces of all the C1 - C7 vertebrae. ∘ connective tissue is positioned to provide connection between the rear inner surfaces of all the C2 - C7 vertebrae. ∘ connective tissue is positioned to provide connection between the front inner surfaces of all the C2 - C7 vertebrae. ∘ connective tissue is positioned to provide connection between the rear bottom-top surfaces of the consecutive vertebrae in all the C2 - C7 vertebrae, • seven vertebrae that are modeled based on scanned human cadaver data, • four muscle interfaces (21-23 and 28) that are formed as cylindrical holes inside the elements used in the neck model and that provide stiffness to the neck by the muscles passing therein, and • at least one sensor set installed on the bottom neck vertebra of the neck model in order to collect physical data of the collision and to detect the loads acting on the neck model. • five intervertebral discs that are positioned between the vertebra 3 and the vertebra 7, the intervertebral discs and eight types of ligaments (13-20 and 26) that connect the vertebrae with each other where internal structure of the capsular ligaments connective tissue forms the facet joints wherein; ∘ connective tissue is positioned to provide connection between the front bottom-top surfaces of the C1 and C2 vertebrae ∘ connective tissue is positioned to provide connection between the bottom-top surfaces of the right and left parts of the consecutive vertebrae in all the C1 - C7 vertebrae. ∘ connective tissue is positioned to provide connection between the rear bottom-top surfaces of the C1 and C2 vertebrae. ∘ connective tissue is positioned to provide connection between the front inner surfaces of the C1 and C2 vertebrae. ∘ connective tissue is positioned to provide connection between the front surfaces of all the C1 - C7 vertebrae. ∘ connective tissue is positioned to provide connection between the rear inner surfaces of all the C2 - C7 vertebrae. ∘ connective tissue is positioned to provide connection between the front inner surfaces of all the C2 - C7 vertebrae. ∘ connective tissue is positioned to provide connection between the rear bottom-top surfaces of the consecutive vertebrae in all the C2 - C7 vertebrae, ∘ connective tissue is positioned to provide connection between the front bottom-top surfaces of the C1 and C2 vertebrae ∘ connective tissue is positioned to provide connection between the bottom-top surfaces of the right and left parts of the consecutive vertebrae in all the C1 - C7 vertebrae. ∘ connective tissue is positioned to provide connection between the rear bottom-top surfaces of the C1 and C2 vertebrae. ∘ connective tissue is positioned to provide connection between the front inner surfaces of the C1 and C2 vertebrae. ∘ connective tissue is positioned to provide connection between the front surfaces of all the C1 - C7 vertebrae. ∘ connective tissue is positioned to provide connection between the rear inner surfaces of all the C2 - C7 vertebrae. ∘ connective tissue is positioned to provide connection between the front inner surfaces of all the C2 - C7 vertebrae. ∘ connective tissue is positioned to provide connection between the rear bottom-top surfaces of the consecutive vertebrae in all the C2 - C7 vertebrae, • seven vertebrae that are modeled based on scanned human cadaver data, • four muscle interfaces (21-23 and 28) that are formed as cylindrical holes inside the elements used in the neck model and that provide stiffness to the neck by the muscles passing therein, and • at least one sensor set installed on the bottom neck vertebra of the neck model in order to collect physical data of the collision and to detect the loads acting on the neck model.
