stomped my feet upon the ground. As my feet were weary‚ I felt a razor edge‚ I use my feet and my keen eyes to scrutinize the razor edge‚ turns out‚ the sharp edge was actually a decayed bone. The yellow‚ white bone with the sharp trowel edge was lying below my feet. I tried to use my feet to pick up the bone‚ but no luck yet. I tried again after stretching my legs and still no luck.

in the joint‚ permitting almost frictionless movement of joint bones at their points of contact. The frictional resistance of normal joints is the cartilage layer to absorb the shock associated with joint use. When weight is loaded onto the joint‚ the cartilage layer compresses. Once the weight is removed‚ the cartilage rebounds to its original dimensions. The articular cartilage is firmly attached to its underlying subchondral bone by a subchondral plate. This allows the subchondral plate to act

Glucosamine has long been given to humans who are suffering from joint conditions and arthritis‚ and there is good logic behind it. Glucosamine is a naturally occurring substance that is one of the main building blocks of cartilage on bones. The job of cartilage in bones is to aid lubrication within the joint and

Bone mineral density by Dual-energy X-ray absorptiometry (DXA) showed a total body Z-score of -3.4 indicating bone mineral density below normal range. Molecular genetic testing identified a pathogenic mutation in the IFITM5 gene‚ confirming a diagnosis of osteogenesis imperfecta‚ type V. The Condition Osteogenesis

Osteoporosis occurs when the body does not absorb the required amount of bone mineral density (BMD)‚ which reduces bone strength. Both men and women have different factors that can increase the risks of getting osteoporosis. This article explains that MS is the second

More detailed X ray images revealed reduced bone mass in the head and neck regions of the injured femur‚ in the ends of other long bones of the body and in the vertebrae. Surgery was necessary to repair the fractured femur and a biopsy of the bone tissue indicated that the composition of the osteoid was normal. Healing of the fractured femur is proceeding slowly. 1.
