Резюме: Objective: This study attempts to provide a more realistic mathematical model of the human head and neck as two separate segments of the human body. Materials and methods: We provide analytical expressions for the mass, center of mass, volumes, and principal moments of inertia of the head, and neck segments individually, and in the combination of them as “head and neck” segments. Results: A different approach to modelling the head and neck was suggested in the current study: i) The head is modelled as a prolonged spheroid; a horizontal plane cuts it forming a cross-section with the proper dimension delivered by the measurement of the neck, thus allowing for a smooth connection of the head with the neck at this cross-section. ii) The neck is modelled as a cylinder. Discussion: Thus far, most models have represented the head and neck as an ellipsoid. We tackled this problem in the present study and employed a different “head plus neck” model. We employ mathematical modelling to ascertain the mass-inertial properties of the segments that are being studied. Conclusion: In the present article, a more realistic and closer to the real shapes of head plus neck mathematical modelling is proposed. Provided that readily measurable anthropometric measurements are obtained, this modelling can be applied to any individual belonging to any race or gender.
