Background Osteogenesis Imperfecta (OI)‚ also known as brittle bone disease‚ is a genetic mutation. I chose Osteogenesis Imperfecta because I wanted to inform the people about the seriousness of this disease. People with this disease have weak bones due to a mutation affecting the collagen in the body. This causes people to have fragile bones‚ which will fracture easily. People may also be very short because of their weak bones. Types of this condition can be mild‚ it can also be very severe. This

health care assistant. Mr T was admitted with a broken radius and ulna; this means that your forearm is made up of two long bones that sit side by side. The inside bone is called the ulna‚ and the outside bone is called the radius. You have broken both bones. A fracture means just the same as a break. The bone ends are out of line and may be overlapping. Without an operation‚ the bones would heal‚ but not in their correct position. You would not be able to turn your hand from palm up to palm down.

This is a chronic a progressive medical condition. Our joints are covered with cartilage‚ when this thick rubber like protection wears down; the bone becomes exposed‚ causing friction of bones. During this process inflammation and swelling can cause severe pain. In severe cases the bone grinds on one another causing fragments to break and chip away. This can be caused by a number of variables‚ or simply by an injury to a joint. Torn cartilage‚ dislocated joints and

ANATOMY AND PHYSIOLOGY OF THE ANKLE The essential structures of the ankle can be categorised into the following; Bones and joints Ligaments and tendons Muscles Nerves Blood vessels Bones And Joints The ankle joint is comprised of three bones: the talus‚ also referred to as the anklebone‚ the tibia and the fibula (Figure 1) (Yufit & Seligson 2010). The way in which these three bones connect to form the joint and to enable movement‚ in particular‚ dorsiflexion and plantar flexion‚ is by the top of

the esthetic zone (De Rouck‚ Eghbali‚ Collys‚ De Bruyn‚ & Cosyn‚ 2009; La Rocca et al.‚ 2012). Several classifications have been proposed for gingival biotypes. Ochsenbein and Rose (1973) stated that the gingiva follows the contour of the underlying bone and tooth shape; accordingly‚ they described two gingival anatomies namely (I) thin scalloped‚ which refers to the triangular-shaped teeth with scalloped gingival margins and (II) thick flat‚ which refers to square-shaped teeth with flat gingival margins

reproductive organs possessed by an individual. Genotypes‚ rather than phenotypes represent the sex of someone. Forensic anthropologists look at a few different morphologies when estimating the sex of a deceased individual. For instance‚ the size of bones and statures can be a key determinant of sex. In typical biology‚ “males exhibit larger stature‚ more robust cranial and facial features‚ greater muscularity‚ strength and speed‚” than females (Krishan‚ 2016). This increased size in male skeletal

religious practices occurred. However‚ it is not until the Shang Dynasty when actually records of spiritual communication were founded. Oracle Bones were recorded of communication between human and spirits. The ritual of cracking oracle bones told what ancient Chinese concerned the most – the relationship between spirits and nature. The intricate Oracle Bones not only reveal the religious aspect of the Shang Dynasty‚ but also relate the cultural and political system in ancient China. During the Shang

Calcium is an extremely important factor for health and longevity. It serves both a structural and physiological role in the entire organism. Bones are constantly breaking down and rebuilding‚ and calcium is directly involved in this process. Calcium ions (Ca2+) are essential mediators of a wide variety of cellular activities‚ including the passing of information along neurons and between adjacent neurons. Hormonal regulation is also mediated by the proper functions of calcium and calcium ions

the present article‚ the authors investigate the use of flame spheroidized hydroxyapatite particulates in a PEEK polymer for usage as bone analogue materials. Metallic implants have been used for orthopedic implants in the past‚ but polymeric implants have been explored due to stress-shielding issues associated with metallic implants. Wolf’s Law states that if bone is not subjected to mechanical stimuli‚ then it will be absorbed (Uhthoff and Dubuc‚ 1971). Therefore‚ it is important to develop a
