This 3D CT reconstruction of the skull beautifully demonstrates the coronal, temporal and lambdoid sutures. The skull sutures represent the juncture of the different membranous bones that form the skull. The coronal suture is the juncture between the frontal and parietal skull bones. The temporal suture seperates the parietal and temporal bones. The lamboid suture is the juncture between the parietal and occipital bones.
