INTRODUCTION
Bone is a living, complex, hard tissue that constitutes the vertebral skeleton. It is a composite comprising of well-defined structures at different scales of hierarchy. It has an organic matrix phase composed primarily of collagen, with the inorganic phase embedded in it. The calcium and phosphate containing inorganic crystals ultimately form hydroxyapatite. The bone morphology can be describes as comprising of the cortical bone - the outer compact region, and the trabecular bone - the inner spongy region. The composition variations in these regions provide the required anisotropy and consequently the load bearing strength to the bone. The functions of the bone in the body include mechanically supporting soft tissues, protecting vulnerable organs, …show more content…

The regeneration process is a well-controlled series of events, involving various cellular components and signaling pathways, aimed to restore the bone function. The main cells responsible for the formation of bone are osteoblasts, which are derived from osteoprogenitor cells. They are present on bone surfaces, and aid in matrix formation and mineralization. They can further turn into bone lining cells if flattened or into osteocytes if they get trapped in the matrix. Osteoblasts are fully differentiated cells, and so formation of bone is entirely dependent on the presence of osteoprogenitor cells, which can migrate to target regions, proliferate and undergo differentiation into osteoblasts. They can be further classified as determined and inducible osteoprogenitor precursors, based on whether a stimulus is required for its differentiation. Osteoclasts also play a major role in bone remodeling. They are associated with the breaking down and resorption of bone tissue during its growth and healing. All of these bone cells are located within and upon the cortical and spongy bone

This study examined the differences in articular surface morphology of caudal vertebrae between prehensile and non-prehensile tailed primates. Articular surface is skeletal surface, which includes bone and cartilage, that makes contact with other skeletal surface as part of a joint. Variation in the morphology of articular surface can confer a greater capacity for mechanical loading, which is required for prehensile primates as they often use their tails to suspend their entire weight during locomotion. In this experiment, it was hypothesized that articular surface area and curvature in caudal vertebrae could be used to distinguish between prehensile and non-prehensile tails. The results showed that articular surfaces found in both proximal and distal regions were greater in prehensile tailed primates, in comparison to primates that were non-prehensile tailed.

Chapter six welcomes us into the skeletal system by presenting functions,types,structure, and development of bones. We are also presented the ideas of fractures and even the spine- curling snap of a broken bone which means a band aid simply won 't do! For example, Hematoma formation , Fibrocartilaginous callus, Bony callus ,and Remolding must occur to heal ,aka 3-10 weeks in a signature infested cast ,and if the break eventuated* on your arm, a complementary farmer 's tan. The Axial Skeleton makes an appearance by explaining itself as lying in the middle of the body and consisting of the skull, hyoid bone, vertebral column, thoracic cage, and middle ear bones. The complexity, physiology and delicate fashions of each member of this group is expressed.

Many people may assume that bones are all the same. However, bones can be classified by shape, structure, and bone markings. Bones are categorized as sutural, irregular, short, flat, long, and sesamoid bones based on their shape (Martini et al. 180). The long bones contain a diaphysis, epiphysis and metaphysis. The diaphysis in the long bone is made of compact bone which has a medullary cavity where marrow is kept.

Collagen, like rope, aims to maximize bones elasticity. And cartilage acts as a buffer. Together these molecules cooperate in order to give bones structure, strength, and support. This relates to animals in the sense that all “animals have molecules that lie between their cells, specifically collagens and proteoglycans.” Through the molecules, cells are able to communicate amongst each other thereby knowing when and how to change their behavior.

The FGFR3 protein spans across the cell membrane resulting in one end inside the cell and the other outside the cell allowing the protein to interact with growth factors outside the cell and receive signals for growth and development. The FGFR3 protein in the bone cells help control bone growth through a process previously mentioned called ossification, where cartilage is transformed into bone using calcium. When growth factors bind to the FGFR3, the protein is activated and FGFR3 is able to regulate ossification. When the Gly380Arg mutation occurs, it results in the FGFR3 protein being absent or damaged therefore preventing it from interacting with external growth factors causing the loss of control of ossification. This causes problems during bone development where cartilage fails to turn into bone.
