3D modeling for sagittal suture

Sagittal suture has a complex pattern which is formed by collision of edges of left and right growing parietal bones. There is fibrous tissue between the left and the right parietal bones, where an osteoblast becomes a basis of ossification. We simulate the growth and the collision of the bone by using the Eden growth model in 3-dimensional space (3D) and obtain a pattern which is similar to the sagittal suture on the inner surface as well as on the outer surface of the calvaria.
