Summary
The SiNuPrOs model offers a comprehensive multiscale and multiphysic approach to cortical bone, integrating structure, fluid dynamics, and mineralization. This advanced model enables detailed study of bone
Area of Science:
- Biomaterials Science
- Computational Mechanics
- Bone Physiology
Background:
- Existing cortical bone models often oversimplify its complex architecture and physical properties.
- A need exists for more integrated models that capture multiscale and multiphysic phenomena in bone.
Purpose of the Study:
- To introduce the SiNuPrOs model, a novel multiscale and multiphysic computational framework for cortical bone.
- To demonstrate the model's capability in simulating elastic properties at the macroscopic scale.
Main Methods:
- The SiNuPrOs model integrates five structural levels and multiple physical aspects (elasticity, piezoelectricity, porous medium, fluid, mineralization).
- It employs 18 structural parameters using homogenization theory and 10 physical parameters.
- A new behavior law was developed for collagen as a piezoelectric medium to simulate mineralization.
Main Results:
- The study presents the SiNuPrOs model and its application to compute macroscopic elastic properties of cortical bone.
- The model's computational methods are implemented in SiNuPrOs software, enabling predictive simulations.
Conclusions:
- The SiNuPrOs model provides a more complete approach to understanding cortical bone complexity.
- It allows for detailed investigation of elastic, fluid, and piezoelectric properties across different architectural levels.

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:22Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:08Overview of the Skull
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:17Gross Anatomy of Bone
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in adults, it...

01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...
