Apply the Rule of 70: Take the number 70 and divide by the percent of change per year. The result is the length of time it will take to either double or halve (depending on whether the change is a decrease or increase) the amount of bone loss
answer: 17.5 years ———— Video 3: - soluble materials, and you can tell by the charge on those ions, calcium, phosphate, the PO4, triple minus and the OH minus, these are all soluble, they're all in blood. -connect together by a series of complicated mechanisms to make bone and of course to make teeth. -« calcium apatite." = "absorption process." -problem=resorption(the loss or breakdown of the bone material) The solubilization(making more soluble the bone material so that the material is lost) -osteoclast(series of cells) -these cells liberate acid in their action. -acid is what is taking away the bone material. - it makes it possible to take away the calcium and to take away bone material. -Leaving behind a spot or a place where there is less bone material -it leaves behind in this instance a pit, or a spot where there is less bone material and it has been weakened. -Fosamax material inhibits osteoclasts from functioning. -the initial stages of this analysis is that about 3% a year, just - other studies have led researchers to understand that Fosamax has caused some jaw bone problem. -Osteonecrosis of the jaw= a killing in effect of the jaw -remedies for osteoporotic treatment=Zometa (two phosphate units) ****isn’t one medication that's going to work well for absolutely everybody. -The process of absorption(putting back or making the bones=- osteoblast. - "B" is the buildup. -buildup of the osteoblast is that there's a matrix of protein and mineral material that is put together by the body. -The matrix is synthesized, and then it is mineralized to this material we call bone or hydroxyapatite - once the bone has been put together by the protein material, the minerals, namely the calcium, is implanted by the osteoblast process ———- Label the cell type associated with bone building (a) and bone loss (b) as represented in the image below. (Note: Ca = Calcium). Enter your answers in the boxes below and then click "Check my answer." (a) osteoblasts These cells are associated with the deposition of bone mass. (b) osteoclasts
These cells are associated with the resorption of bone mass. ——— Video 4: -how can one tell if one has low bone mass -Blood is more complicated, to analyze it by way of the blood, but the ones that work the best are a noninvasive, single-photon, or double-photon absorptiometry methodology -another method called FRAX= bone density analysis -femoral neck, this is where the data was obtained on the bone density as you see in a vertical column going from 0.5 to 1.2. -someone with a relatively high femoral neck bone density that is above a number of the people in the other, non-depressed category.
