The first recorded spelling of the family name is shown to be that of Gamel Mercer, which was dated 1168, in the Pipe Rolls of Lincolnshire, during the reign of King Henry 11, known as The Builder of Churches, 1154 - 1189.Surnames became necessary when governments introduced personal taxation.uring the Middle Ages the term was used particularly of someone who dealt in textile fabrics, especially the expensive and luxurious types of cloth such as silks, satins, and velvets. Job-descriptive surnames originally denoted the actual occupation of the namebearer, and later became hereditary.
Osteoporosis is a disease where decreased bone strength increases the risk of a broken bone. It is the most common reason for a broken bone among people who are old.Bones that commonly break include the back bones, the bones of the forearm, and the hip. Until a broken bone occurs there are typically no symptoms.steoporosis is defined as a bone density of 2.5 standard deviations below that of a young adult. This is typically measured by dual-energy X-ray absorptiometry at the hip.
What is Osteoporosis and Definition. Osteoporosis is a condition of diminished BONE DENSITY (the extent of mineralization of the bones). Though some loss of mineralization is a normal process of aging, osteoporosis represents an accelerated loss that causes health problems.Osteoporosis weakens the BONE structure; increases the risk for FRACTURE; and may result in bone deformities, particularly of the spine.RAY shows a characteristic porous structure to the bones, demonstrating the loss of mineral content and bone mass. Bone density tests such as DEXA scan can detect demineralization before fracture occurs. Doctors use a scale of relative percentage of bone loss to measure the severity of osteoporosis.
