Osteoporosis is a skeletal disorder characterised by low bone density weakening of bony tissue. When this occurs bones are more prone to fractures Bone loss happens without any symptoms that’s why some individuals might not know that they have osteoporosis until the bones are so weak and fragile. Women are affected by osteoporosis than men because women have lower dense bone mass and an increased rate of low bone mass especially after menopause. Primary osteoporosis is the most common type of…

diagnostic medical sonography, diagnostic x-ray, and bone densitometry. Osteogenesis Imperfecta (OI) is a genetic disease affecting the quantity and structure of collagen that is normally found in connective tissues, bones, and the sclera, or white portion of eyes. It is estimated that this condition affects 1 in 10,000 to 1 in 20,000 births (Antoniazzi, Mottes, Fraschini, Brunelli, & Tato, 2000). The abnormalities of the collagen produce fragile bones that are susceptible to breaking, even with…

The human knee joint is a diarthrosis, or synovial joint, made up of multiple different tissues that work together to provide function. Everything from the outer layer of the skin to the core of the bone is necessary for the joint to articulate properly. The most superficial layer of the knee is the skin, which is the largest organ of the human body and is made up of the epidermis and dermis, which in turn are made up of keratinized stratified squamous epithelium as well as dense, irregular…

Types of Bone Fractures  Avulsion • A muscle or ligament pulls on the bone, fracturing it  Comminuted • Bone is shattered into many pieces Compression • Generally occurs in the spongy bone of the spine, for example a portion of the vertebra in the spine may collapse due to osteoporosis Fracture Dislocation • A joint becomes dislocated, and one of the bones of the joint has a fracture Bone Fractures Cont.  Greenstick Fracture • Bone partly breaks on one side, but not…

With osteoporosis, new bone creation doesn’t keep up with old bone removal. This makes bones weak. Causes/Risk Factors Osteoporosis is a silent disease and is not often found until someone has a bone fracture. Occurs when there is an imbalance between new bone formation and old bone resorption. Two essential minerals needed for bone function are calcium and phosphate. Risk factors include aging and calcium deficiency. Osteoporosis…

response to ultraviolet light exposure however dancers spend long periods of time indoors so have limited exposure to sunlight, as a result they are often vitamin D deficient which can lead to injuries and underperforming. The importance of vitamin D should not be overlooked as ‘Vitamin D receptor sites have been identified in virtually every tissue within the body’. Vitamin D is important in aiding the absorption of calcium which improves bone strength, muscle contraction and blood clotting. …

Pathophysiology of Osteoporosis Osteoporosis is a condition of skeletal fragility due to progressive loss of bone mass. Losing bone is a normal part of the ageing process, but some people lose bone density much faster than normal. This can lead to osteoporosis and an increased risk of fractures. It occurs in elderly people of both sexes but is most pronounced in postmenopausal women, they lose bone rapidly in the first few years after the menopause (when monthly periods stop and the ovaries stop…

1. The skull bones protect the brain from injury, the vertebra surrounds the spinal cord and the rib cage helps protect important organs of the thorax. Some examples are: the bones in our skull protect the brain and the ribs protect the heart and lungs. The bones make a structure that supports our body and holds and protects soft organs. Some examples are: the bones of the lower limbs provide support to the body trunk when we stand, and the rib cage supports the thoracic wall. 2. The skeletal…

provided enough of this substance which is essential for building and maintaining strong bones. It also helps muscles work and nerves deliver messages from the brain to other parts of the body. But not everyone has a clear knowledge about this substance. And the question: Is a calcium supplement right for you? need answering. Body: What is the benefit of calcium supplement? Calcium is an essential matter for bones’ growth and human body development. Your…

When bones and muscles connect a joint is formed. At this point both are joined together by the help of tendons, which is a connective tissue. When we have to move a joint the muscle receives an electrical signal from brain. It causes movement to occur, because this causes the contraction in it. This contraction pulls on the corresponding bone at its insertion point. Stationary bone is called the point of origin for the skeletal muscle, while the one which moves is known as the point of…
