Effect of Vitamin D in Bone Health Introduction One of important micronutrients for the maintenance of bone health is the vitamin D. Without enough vitamin D, bones can become weak and break, therefore the fracture risk increases. “In 2010 the Institute of Medicine (IOM) reported that, vitamin D deficiency is not a problem for the majority of Americans. The most recent NHANES (National Health and Nutrition Examination Survey) data on vitamin D status in the U.S. population published by the…

step in the process is that a 3-D image of the outer surface of the femur is made. The bone was laser scanned at the physical anthropology computer lab using a special 3-D laser scanning machine. Resulting data was a highly accurate representation of the superficial topographic features of the bone the initial 3-D data set contained eighty thousand facets. The second step was generating a 3-D model of the femur. The model was made to be manipulated digitally. The 3-D digital data was transferred…

off a study that was done in Iran that concluded that vitamin D deficiencies could double the risk of schizophrenia. Why the author chose a study conducted in Iran to prove a false claim about Americans is beyond me. There isn’t any critical analysis of the study that was done in Iran, and I don’t see how it connects to American prevalence of schizophrenia to begin with. Couldn’t it then be said that anyone in the world with a vitamin D deficiency has double the risk of developing…

Fibrous dysplasia is a skeletal disorder in which bone forming cell fail to mature and produce too much fibrous or connective tissue. Fibrous dysplasia is a rare bone disorder in which scar tissue develops in place of normal bone. This can weaken the affected bone and cause it to fracture.Fibrous dysplasia is linked to a gene mutation that affects the cells that produce bone. The mutation occurs after conception, in the early stages of fetal development. Which means the mutation isn't inherited…

Have you seen that bony lump at the inside of your big toe joint? If you did, you are most likely to have a bunion. This enlargement is actually a misalignment of your big toe joint, which can have additional bone formation in some cases. Such misalignment makes your big toe to point outward going to your small toes. Bunion, or medically termed as hallux valgus, is a progressive condition that worsens over time. There is a less common bunion called bunionette or tailor's bunion, which is…

Osteoarthritis is a worldwide chronic condition that has impacted the lives on many people today, causing pain, deformity, and difficulty with daily physical tasks. This chronic condition is, “believed to have a genetic cause or predisposition, and is caused by wear and tear on a joint. The cartilage wears away and exposes the bone.” (Rosdahl and Kowalski, 2006, p.1235) This chronic condition generally targets individuals with obesity and it is most commonly found among women. The…

from a fractured bone by laying down the bone matter (calcium salts) there after osteoclasts moves in to remove excess bone debris. Osteoclasts and Osteoblasts work as a team, one breaks down the other repairs. 4. How does Vitamin D support bone formation? Vitamin D supports bone formation by helping the calcium in our bodies pass through the lining of the small intestine and into our…

Bone Metastasis Bone metastasis is cancer that spreads to the bones from another part of the body. A person may have bone metastasis in one bone or in more than one bone. Cancer that spreads to the bones is different from cancer that starts in the bones (primary bone cancer). Bone metastasis is more common than primary bone cancer. The spine is the most common area for bone metastasis. Other common areas include the: • Hip bone (pelvis). • Ribs. • Skull. • Long bones of the arm or…

Osteoporosis is a prevalent disease affecting over 1 million Australians. This disease makes bones become brittle leading to a higher risk of breaks than in normal bone. Osteoporosis occurs when bones lose minerals, such as calcium, more expeditiously than the body can supersede them, causing a loss of bone thickness (bone density or mass). 4.74 million Australians over 50 have osteoporosis or poor bone health. In 2011-12 the estimated prevalence of diagnosed osteoporosis among those aged 50 and…

Some individuals may believe that they are only able to receive social security disability payments if they happen to be visibly disabled, such as a condition that causes you to be in a wheelchair or being legally blind, but that’s not the case. One such condition that is not readily apparent that can qualify you to receive social security disability is parathyroid gland disorders. What is Parathyroid Gland Disorders Parathyroid gland disorders is an endocrine disorder, and your endocrine…
