Q. What is the function of the calcium salts in the bone matrix?
Bone matrix is a bonding of multiple fibers and chemicals of different materials including collagen fibers and crystalline salts (calcium and phosphate). Collagen fibers provide tensile strength, whereas calcium salts provide compressional strength to the bone.

Q. What is stored in the matrix of bones?
The inorganic matrix contributes approximately ∼65–70% of the wet weight of bone and serves as an ion reservoir storing approximately 99% of total body calcium, approximately 85% of phosphorus and between 40 and 60% of the body’s sodium and magnesium.
Q. What are mature bone cells that monitor and maintain your bone matrix?
Osteocytes are mature bone cells, differentiated from osteoblasts, which are responsible for maintaining the bone matrix. They can synthesize and resorb (break down) the matrix to maintain homeostasis.
Q. What types of cells are responsible for dissolving excess bone?
OSTEOCLASTS are large cells that dissolve the bone. They come from the bone marrow and are related to white blood cells. They are formed from two or more cells that fuse together, so the osteoclasts usually have more than one nucleus. They are found on the surface of the bone mineral next to the dissolving bone.
Q. What are the 4 types of bone cells?
Bone is a mineralized connective tissue that exhibits four types of cells: osteoblasts, bone lining cells, osteocytes, and osteoclasts [1, 2].
Q. Which type of cell builds bone?
Osteoblasts
Q. Which type of cartilage is used in bone repair?
The repair tissue between the broken bone ends, the fibrocartilaginous callus, is composed of both hyaline and fibrocartilage.
Q. What are the conditions that describe bone loss which is more severe?
The bones that make up your spine (vertebrae) can weaken to the point that they crumple, which may result in back pain, lost height and a hunched posture. Bone fractures, particularly in the spine or hip, are the most serious complications of osteoporosis.
Q. What diseases cause low bone density?
6 Medical Conditions Linked to Osteoporosis and Bone Loss
- Diabetes Mellitus and Osteoporosis. For reasons scientists still don’t fully understand, people with type 1 diabetes tend to have lower bone density.
- Lupus and Rheumatoid Arthritis.
- Hyperthyroidism.
- Celiac Disease.
- Asthma.
- Multiple Sclerosis.
Q. Can you live 20 years with osteoporosis?
This excess risk is more pronounced in the first few years on treatment. The average life expectancy of osteoporosis patients is in excess of 15 years in women younger than 75 years and in men younger than 60 years, highlighting the importance of developing tools for long-term management.
Q. Is sitting bad for osteoporosis?
“If you have low bone density, however, and you put a lot of force or pressure into the front of the spine — such as in a sit-up or toe touch — it increases your risk of a compression fracture.” Once you have one compression fracture, it can trigger a “cascade of fractures” in the spine, says Kemmis.
Q. What is a bad bone density score?
A T-score of -1.0 or above is normal bone density. Examples are 0.9, 0 and -0.9. A T-score between -1.0 and -2.5 means you have low bone density or osteopenia. Examples are T-scores of -1.1, -1.6 and -2.4.
Q. Are osteoporosis drugs worth the risk?
For Most, Osteoporosis Treatment Benefits Outweigh Risks “When these drugs are used appropriately, they are safe as compared with many other things that we do in medicine. They will provide a lot more benefit than the risks that they pose,” he says.
Q. What is the best injection for osteoporosis?
Denosumab injection (Prolia) is used treat osteoporosis that is caused by corticosteroid medications in men and women who will be taking corticosteroid medications for at least 6 months and have an increased risk for fractures or who cannot take or did not respond to other medication treatments for osteoporosis.
