3D Dynamic Modeling of the Head-Neck Complex for Fast Eye and Head Orientation Movements Research

Figure 5

Detail of the submodel for the bony structures and intervertebral disks in Simulink-SimMechanics. Blocks skull, C1, C2, and C3 are rigid bodies receiving their corresponding net force and moment from muscles, ligaments, and facet joints through body actuator interfaces (at the left). The joint between the occiput and C1 is represented as a spherical joint in SimMechanics and the different disks are represented as bushing joints in SimMechanics (see Figure 6).
