The Osteoblast: One Of The Four Bone Cells In The Human Body

Our bone tissues are made of a much harder substance than the cartilage, but they can be worn away by friction. They are tough on the outside, but on the inside they have a sponge-like design that helps to reduce the weight while retaining strength. They are designed to maintain the body’s structure and support the body’s movement and are used to protect weaker tissues, such as the brain, lungs and heart.

The skeletal system is made up of cartilage and bone. Both bone and cartilage are connective tissues, that is, they are composed of cells in a matrix with intracellular fibers. Just imagine connective tissue as a gelatin salad with grapes and coconut. The grapes would represent cells, the gelatin the support material for matrix, and the pieces of coconut the intracellular fibers. By changing the amounts of each ingredient and adding extra substances, we can produce a material that is very hard like bone and can withstand weight or softer like cartilage which can be used as a cushioning material.

Osteopetrosis is a rare, genetic disease that causes extremely dense and brittle bones. This is because individuals affected with osteopetrosis do not have normal osteoclasts, which bones need to work correctly. Healthy bones require properly functioning osteoblasts and osteoclasts. Osteoblasts are responsible for making new bones and osteoclasts are bone cells that are responsible for bone resorption, which is the breaking down of bones and providing space for new bone marrow to grow. An individual with osteopetrosis has osteoclasts that do not function properly, therefore their bones are not healthy (Stocks, Wang, Thompson, Stocks, & Horwitz, 1998).

It also protect soft internal organs for an example brain and heart from injury. Skeleton with muscle is strong bones that can enable the body to move freely. Individuals who is at increase risk for fractures may be difficult to heal because of the weakened bones. This can lead to loss of mobility, the inability to retain independent living and even death. Osteoporosis can gives a huge effect to human skeletal due to decreased mineralization of the bone. Human skeletal consist of two types of bones which is compact bones and spongy bones. Compact bones is a bone that has a solid outer surface while spongy bone is inner bone that less dense than compact bone which has many holes like sponge. A spongy bone does not have osteon.The matrix forms an open network of trabeculae. Healthy bone is dense enough to support and protect body and to handle stresses of movement and minor injuries while osteoporosis has abnormally thin bones with larger holes on spongy

The bone is made up of combined bones, bone marrow. Bone marrow is found in the middle of the main bone and it has blood vessles.There is two types of bone marrow are the red and the yellow. This type of cancer my effect the red blood cells, white blood cells, and

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.

During the later years, osteoporosis becomes apparent but develops a lot earlier without any warning. The bone has two compartments, which include the cortical bone and the trabecular bone. The cortical bone is the very dense bone tissue that forms the outer shell, whereas the trabecular bone is the

Bone marrow- connective tissue found in spaces inside bone that is the site of blood cell production and fat storage

The University of Cambridge indicates that there are two types of bone in the human body: cortical, or compact, bone and cancellous bone, which is also known as spongy or trabecular bone. Cortical bone accounts for 80 percent of the body's bone mass. This type of bone forms a cylindrical shaft around the marrow in the central part of the bone. Cancellous bone makes up only 20 percent of the body's bone mass, but it has a much higher surface area because of its higher porosity and honeycomb structure, according to the University of

It is present in the big size bones, such as breast bone, hips and spine where it creates new blood cells. The blood cells include white blood cells (leukocytes), platelets and the red blood cells (erythrocytes). In patients who are suffering from ailments such as Leukemia, aplastic anemia or other immune deficiency sicknesses, the stem cells in the marrow create abnormal blood cells that deter the production of normal blood cells. In a transplant, the diseased marrow that is making the abnormal blood cells is demolished by treatments such as chemotherapy and radiation and is substituted by healthy marrow. This healthy marrow substitutes the dysfunctional one that was present in the craters of the bones and begins producing healthy blood cells. If fruitful, this treatment might totally cure the patient of his disease. It might take as long as one year for the transferred marrow to begin performing its functions at the optimum level. During this time period, the patient has to undergo repeated inspections for any complications that might befall.

Osseous tissue provides essential functions in the body. It protects our vital organs and the bone marrow within this tissue provides our bodies with blood cell production needed to support our other internal organs. Ligaments connect our bones together by joints to allow for our bodies flexibility. In essence, if we didn't have bones, we wouldn't have the proper blood cell production to support our other organs. Without bones we wouldn't have the proper protection against damage to our internal organs. without bones we wouldn't have the muscles and ligaments to allow us to have flexibility. In whole, without bones we would have no way to move to take care of ourselves. We would have no way to protect our internal organs from damage. Most importantly,

Bones, whether dead or alive, provide protection, support, and account for numerous other functions for the body. Although bones are not breathing, walking, or talking, bones are comprised of living tissue and blood vessels. Blood vessels keep the bones alive because the vessels provide a passageway through pores that give oxygen, nutrients, and calcium. The vessels also keep out metabolic wastes that could strongly affect the bone health and strength. Bones are made up of repair structural tissue, also known as living cells. These living cells work rapidly to develop new tissue for damaged parts of the bone. Research suggests nerves are also included in the bone to assist in human nervous system regulation. This regulation, helps the body

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

Osseous tissue contains specialized cells, cell products, and a fluid matrix. The distinctive solid, stony nature of bone results from the deposition of calcium salts within the matrix. Crystals of calcium phosphate account for almost two-thirds of the weight of the bone. The majority of
