The Behavior of the Virtual Human Head-Neck System during the Main Movements

The subject of this paper permits the cooperation between many researchers which activate in different fields, which have the capacity to develop informational methods and technologies to solve difficult problems given by the complexity of the scientifically target. Using computer-aided design (CAD) and dynamic simulation programs was developed a virtual model of the cervical human spine that includes the main muscle groups simulated by springs with dynamic parameters, nonlinear and variable. Were studied the main types of movements (displacements) lateral bending (left-right) and flexion-extension movements.
