vascularization to occur during bone regeneration. The hollow pores also allow for high density and mechanical structure, which allows for the shells to withstand high pressures associated with the bone environment. Their main objectives are to protect the organisms within them; therefore they should be mechanically strong enough to withstand environmental pressures.
The Disadvantages of anthropods skeletons are that they are not lightweight despite the fact that they have porous interior structures. Their heavy structure may pose as a hindrance to the patient, by providing extra weight thereby making it difficult to carry out normal functions. They are also not biodegradable, therefore they will remain in the body even as the bone is regenerating,

That means, they will provide excellent mechanical support, with very minimal risk of being damaged in the process of bone regeneration. Antlers are also made of the same organic components that bones are made of; therefore they have a high chance of being biocompatible with the patient bone environment.
Disadvantages include that they cannot be taken from animals so readily, as they pose the risk of endangerment and interference of the cervidae family.
Tusks and teeth are consisted of the same mineral content that normal bone is made of, hydroxyapatite, making it more likely to be biocompatibility with the bone environment. They can be highly vascularized, as they tend to have small pores that are ideal for cell proliferation and bone development. They also consist of type 1 collagen, which is a key component of bone. They have high compressive strength and mechanical properties, as their purpose are to withstand impact in food digestion as well as combat.
In terms of disadvantages, teeth and tusks have a low availability. They pose the risk of poaching and endangerment of animals, as they cannot be readily taken from animals with

The hollows inside of the bamboo help serve the multiple purpose of being a crack deflector, site for vascularization and cell proliferation. The hollows in the bamboo assist with its light weight structure, that ideal for bone implants. As well as having sufficient mechanical properties, bamboo is the only plant based material that acts as a bio composite consisted of fibers, making it potentially biocompatible with the bone environment. The fibers also pose the opportunity of biodegradability, as fibers are capable of breaking down with exposure to certain environmental
Describe the microscopic features of osseous tissue that help long bones withstand compressive forces without breaking.
Bone homeostasis occurs when the bones are being “remodelled” or it is also known as “bone metabolism” this is the process in which new bone is created and the old bone which was there was removed, it is more common to see this process in younger growing children or adults who have broken any bones.
With ABC recipient site classification surgeons gain some insight in to regenerative potential of the surgical bed and can consider some modifications to help increasing of success rate of bone healing and decreasing morbidities of donor sites.
Alumina and zirconia ceramics have been widely used in orthopaedic hip replacements for the past 30 years. The advantage of using these was lower wear rates than those observed using polymers and metals. Because of the ionic bonds and chemical stability of ceramics, they are relatively biocompatible and therefore more preferable to use than metals and polymers. Alumina is most commonly used as a femoral head component instead of a metal in a hip prosthesis because this would reduce the polyethylene wear that is generated. Alumina is a desirable biomaterial to use in hard tissue implants because of characteristics like excellent wear resistance, high hardness, bio inert, low abrasion rate and good frictional behaviour. Furthermore, it has excellent surface finish as well as high fatigue streng...

Human bones and teeth are known for their strong and dense structures. The major component that is being responsible for this property is a mineral called hydroxyapatite. Hydroxyapatite is a mineral that forms through a controlled process of crystalline solid apatite and other various elements. The importance of proper proportions in this process is very significant: all elements (calcium, phosphorous, oxygen, and other ions) need to be available with an adequate amount. 1
The remarkable strength of the bones in this system provides protection for the vulnerable organs in the body.
With this formation, articular cartilage can be found at the ends of our joints, like our knee, for cushion, and it allows for our joints to move without discomfort. Then we have the inside of our bone, which is hollow and allows for blood vessels to penetrate and provide nutrients. Previously referred to in this letter as spongy bone tissue, this tissue has a lattice-like pattern. What may be easier to think of would be your favorite waffle fries from Chik-Fil-A! It is strong, but not as tough as our other type of bone tissue, compact bone tissue. Compact bone covers the spongy bone and provides a tough exterior for one main function: protection. You can think of compact bone as spongy bone’s protector. This is the outer bone that you felt when you were coating the chicken
Osteoporosis is a condition, which advances with age, resulting in fragile, weak bones due to a decrease in bone mass. Externally osteoporotic bone is shaped like normal bone, however it’s internal appearance differs. Internally the bone becomes porous due to a loss in essential minerals, including phosphate and calcium. The minerals are loss more quickly than they can be replaced and in turn cause the bones to become less dense and weak. The bones become prone to fracture, due to their weakness. Therefore the awareness of the disease tends to occur after a fracture has been sustained. The bones most commonly affected are the ribs, wrist, pelvis and the vertebrae.
Normally, teeth stimulate the surrounding bone by compressive and tensile forces, these forces have a piezoelectric effect (which is the ability of a material to give an electric charge in response to mechanical stress) on the crystals and durapatite that synthesize the inorganic
Bone tissue is the subject of Chapter 7. It covers the tissue and organs of the skeletal system, the histology of osseous (bone) tissue, the development of bone, physiology of osseous tissue and disorders of the bone.
... bone to ease the process of bone replacement surgeries to reach that next step. The research conducted recently with wood, sea ice, styrofoam, and the inkjet printer are not currently being used to replace entire bones. These items are not thought to be used for years to come, however, advancing to this level of recreation of human bone is forward progress for replacement surgeries.
Although your teeth are also considered part of your skeletal system, they are not counted as bones. Your teeth consist of enamel and dentin. Enamel is the strongest substance in your body. The main priority of the skeletal system is to provide support for the body. Without bones our body would be in a pile of guts and mush on the floor. Your skeleton furthermore assists to protect your internal organs and fragile body tissues. The brain, eyes, heart, lungs and spinal cord are all sheltered by your
These kinds of polymers have both some advantages and disadvantages. Although they are bioactive and biodegradable and provide high comppressive strength, Degradation of such polymers leads to undesired tissue response due to producing acid formation in degradation process. Metallic scaffolds are another method for bone repair and regenaration. They provide high compressive strength and enormous permanent strength. Metallic scaffolds are mainly made of titanium and talium metals. The main disadvantages of metallic scaffolds are not biodegradable and also discharge metal ions. Recent studies in metallic scaffolds mainly focus on biodegradable materials which can be used improve bioactivity of metals such as titanium.
In this paper I will clarify the relation between the integumentary system and the skeletal system. During this paper I will address how the two systems work together to maintain homeostasis and what occurs when balance is not maintained between the integumentary and skeletal system. During this paper I will explain how osteoporosis is directly linked between both the integumentary and skeletal system and ways to prevent or yield this disease.
