Bones Are Dynamic Organs

Bones are joined together by joints, most of which authorize movement between the bones. Additionally, bones are a form of connective tissues manufactured by osteoblasts, which signifies immature bone cells. Speaking of bone formation, ossification occurs in two ways. One being is endochondral ossification which is established within cartilage, is the most common way the majority of bones form. Secondly, intramembranous ossification structures the flat bones of the skull, clavicle, and mandible. Furthermore, the skeletal system manufactures blood cells, which the process is named hematopoiesis, and archives and exports

Bone is a living tissue and made up of cartilage. Fibrodysplasia ossificans progressiva bone appears as normal bone tissue, but it develops in the wrong places. Osteogenesis and ossification are medical terms which refer to the formation of bone. Most bones in the human body grow and heal up after a break through endochondral bone formation, which is how FOP bones grow. Cartilage forms first and then the bone will eventually take the place of cartilage.

Osteoclasts are bone-absorbing cells that breakdown bone and assist in depositing calcium and phosphate in the blood.

One of the key elements of regulating skeletal growth is the Osteoclasts. The Osteoclasts are responsible for initiating the bone remodeling cycle. Blood vessels and nerves are able to penetrate the bone once the chondrocytes die

The skeletal system is made up of bones and joints. Bones are a dry dense tissue that is composed of calcium phosphorous and organic matter. The bones are protected and covered by a layer of fibrous connective tissue membrane called the periosteum (Brown, et al., 2015, p. 1547). There are two basic types of bone tissue: Compact Bone and Spongy Bone. Compact bones are dense smooth bones, while Spongy bones are composed of small needle-like pieces of bones and open space. Bones are then categorised according to the shape of the bone into four groups: long, short, flat and irregular. Long bones characteristically are typically longer then they are wide and generally have a shaft with heads at either ends e.g. the humerus. They are mainly compact bones. Short bones

Bone tissue is hard and has a calcified matrix (where the pores are filled with calcium) containing collagen fibers; osteocytes (mature bone cells) lie in the lacunae (cavity containing bone cells). The key functions of bone tissues are: support and protect the body structure and provide cavities for fat storage and synthesis of blood cells. Because the matrix of bone tissue is hard and rigid, the tissue is able to provide support and protection to the

Bones are structured to provide strength, protection, and movement. In addition the structure allows the bones to serve as a reservoir for several minerals including calcium because calcium can quickly move between the bone and the blood.

There are approximately two hundred six bones in our body and they're essential in our life. Bones consists of osseous tissue, nervous tissue, and epithelial and muscle tissue. Examples are the femur, humerus, clavicle, and sternum. The bones have many different functions in our bodies, but basically, their main functions are to provide support and protection for the body. Bones provide a framework that supports our body and bones such as skull, vertebrae and rib cage try to prevent internal organs from injuries. Also, bones enable movement by providing points of attachment for muscles and they produce blood cells, also known as hematopoiesis in the red marrow. Lastly, bones store minerals, such as calcium and phosphorus for different cellular activities and store lipids in adipose cells of the yellow marrow as an energy reservoir. There are different shapes and textures of bones. Bones can be flat, such as scapula and sternum, or irregular like the sphenoid bone and vertebra. Also, bones can be short or long. Examples of short bones are the carpal bone and talus and long bones are ulna, femur, and radius. In terms of texture, bones can be compact or spongy. Compact bones are dense and heavy while spongy bones are porous and light. Both types of bones are connective tissues. Usually compact bones are the out layer of a bone and spongy bones are the internal portion of the bone.

What are the roles of osteoclasts in bone formation? Osteoclasts are large cells that function to reabsorb, or to digest bone tissue. They digest bone tissue from the inner sides of bones thus enlarging the inner bone cavity so that the bone does not become overly thick and heavy.

One of the most important function of the bone is support, they provide support for our body and hold organs. Another Function of the bones is protection the rib cage protects our heart and lungs and the skull protects the Brain. Our bones help us move around. Our bones help in the production of Blood cells. Our bones Save energy and minerals like calcium and phosphorus.

Bones provide body structure, protect organs, anchor muscles, and store calcium. Good health habits such as eating nutritious foods and exercising regularly are important for maintaining healthy bones. They can also help prevent thinning and loss of density in the bones (osteoporosis).

Defining the mechanical environment of osteoblasts is even more challenging than of osteocytes. It is unlikely that the model by Weinbaum et al. (1994) can also be applied for matrix-depositing osteoblasts. Unlike osteocytes, osteoblasts are not located within tiny channels and surrounded by a stiff, calcified bone matrix. Osteoblasts can be found on the surface of soft osteoid and newly formed bone mineral at remodeling sites, i.e., in regions with bigger porosities and hence reduced fluid flow and FSS (Liegibel et al., 2004).

Bone serves the organism at multiple levels: As a system, bones permit the organism to locomote effectively and to maintain posture by bearing loads without deformation, by providing rigid attachment sites for muscles and acting as a system of levers to amplify small movements. As an organ, bones protect the viscera and house the hemopoietic tissue (red marrow). As a tissue, bones serve as a reservoir of readily mobilizable calcium, an
