Cartilage and bone are both stiff connective tissues which form an essential structural component of the body of animal organisms‚ including human beings. However‚ they are also quite different in both composition and function. Bones are extremely hard‚ dense tissue which provide a supportive frame for the body ‚ as well as serving as production and storage centers for cells and minerals‚ whereas cartilage is a more flexible tissue found in more specific locations of the body‚ essentially midway

the Silent Orphan phenomenon. It was a subject of deep fascination‚ where numerous attempts have been made in either proving or disproving his existence. So far‚ there was never enough evidence to support the viewpoints of one side‚ and subsequently debunking the views of the other. For some‚ there was evidence to give credibility in the truth behind the Silent Orphan’s existence‚ while there are others who use their senses of logic and reason. But no one has been able prove that the Silent Orphan

Title: Bone Mechanics Objectives:- -To become familiar with LabView software and National Instruments‚ in order to record and observe the strain signals from chicken bone and an aluminum rod. Background: Data acquisition is the use of computer software connected to a measuring device. Signals and measurements are recorded‚ which is converted into a digital signal only understood by a computer. Data is recorded at a certain speed that is processed in real time‚ and can be immediately interpreted

Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex‚ pose a significant health risk to the patient‚ or fail to heal properly.Bone generally has the ability to regenerate completely but requires a very small fracture space or some sort of scaffold to do so. Bone grafts may be autologous harvested from the patient’s own body‚ often from the allograft or synthetic with similar mechanical properties to bone. Most bone grafts

Chemical Composition of Bone Bone is a very hard material which is capable of bearing a large amount of weight and resisting tension and twisting forces. Therefore‚ this material is both flexible and hard. The hardness of bone is due to calcium deposits in the matrix while the flexibility comes from the organic material of the matrix. We can illustrate these facts by treating two bone samples by two different methods: 1. Soaking a bone in vinegar (dilute acetic acid) removes calcium

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

Bone Cancer Bone cancer is when there is an abnormal growth in the amount of tissue in a bone. These strange growths can be either benign or malignant‚ but usually malignant. There are two types of bone cancer; primary and secondary. In primary bone cancer‚ the cancer had actually started in the cells of the bone‚ whilst in secondary‚ the cancer has started in a different area and traveled through the body to the bone. The three main types of bone cancer are osteosarcomas‚ Ewing’s sarcomas‚ and

Bone cancer can be primary bone canceror secondary bone cancer. Primary bone cancer started in the bone; the cancer initially formed in the cells of the bone‚ while secondary cancer started elsewhere in the body and spread to the bone. Examples of primary bone cancer include steosarcoma‚ Ewing sarcoma‚ malignant fibrous histiocytoma‚ and chondrosarcoma. According to the National Cancer Institute‚ USA‚ it is estimated that by the end of 2010 there will have been 2‚650 new cases and 1‚450 deaths

Chem 2450 March 14‚ 2012 Bone Marrow Donation A few weeks ago a woman came to the University of Central Arkansas on a search for a bone marrow donor match. This woman was on the search for a bone marrow match for her friend who has only a few months to live. Her friend just gave birth to a newborn baby and if she does not receive this bone marrow transplant she will leave her baby on this Earth without a mother. Bone marrow is a fatty tissue inside the bone. Inside this fatty tissue there
