Bone Physiology Of Osteoporosis

836 Words2 Pages

Bone physiology is the normal process of the bone to continuously breakdown and remodels themselves. The bone remodeling cycle begins when the osteocytes determine which part of the bone needs to be remodeled and send out signals to osteoclasts to reabsorb the bone. Along with the osteoclasts, the osteoblasts follow behind osteoclasts forming new bone reshaping as it goes in order to accommodate the current stresses on the body. The two types of bone tissue are the spongy bones and the compact bones. The compact bones support the whole body and are the outer part of the bone, whereas the spongy bones are located inside of the compact bone and are used to support the body structure. Calcium is stored in compact bone in high quantities, but very little is stored in the spongy bone.
2. The relationship between calcium and bones is that calcium is one of the minerals that make up the bones. …show more content…

As the osteoclasts are busy reabsorbing parts of the bone normally the osteoblasts would be going behind them to replace the reabsorbed bone. In osteoporosis, the osteoclasts are continuing to do their job reabsorbing bone, but the osteoblasts are unable to keep up with them causing the bones to become brittle. The bone matrix itself remains intact, but the bone mass declines and the bones become porous and light. With the bones becoming more brittle, the possibility of a fracture increases, especially the neck of the thigh bone. If a fracture does occur, it can take longer or require surgical intervention to heal.
5. Scientists know that genetics play a role in who will develop osteoporosis. Being female, especially post-menopausal, is one of the well know genetic risk factors for developing osteoporosis. Others include either being Caucasian or Asian, having a small body frame, low body weight and a family history of maternal

    Osteoporosis comes from the latin word meaning “porous bone”. If you were to look closely at a bone you could see there are these small spaces on the bone which is good, now if you look at someone who suffers from osteoporosis you will see these spaces are much larger. As these spaces become larger it takes away from the strength and integrity of the bone making it grow weak and thin. Osteoporosis is most common in women over the age of 50 and gives them a higher risk of fractures and or breaks especially common in the hips. While we know osteoporosis comes from a number of things it can be broken down to age, the hormonal changes most commonly seen in menopause and a lower intake of Vitamin D and Calcium. Age is the unpreventable factor that doctors or you cannot change. Hormonal changes can be fixed with supplements or hormone therapy along with ones intake of Vitamin D and Calcium. Hormone therapy, estrogen alone or the combination of estrogen and progestin have been proven to prevent and aide in the treatment of osteoporosis in

    An osteoblast is a “baby” bone cell whose main job is to secrete osteoid which forms the hardened, or calcified, bone matrix. Osteocytes are formed from osteoblasts. Osteocytes are the mature bones cells that have been completely differentiated. They are found in the lacunae of hard bone and have a spider-like appearance due to their canaliculi. Osteoclasts are a different type of cell formed from the mesenchymal cells. These cells are not related to osteoblasts or osteocytes. Their job is to basically “eat” the bone to create cavities and other hallow spaces during bone remodeling. Finally, the cells form differentiate to form fibroblasts and fibrocytes. These fibroblasts and fibrocytes secrete and form the matrix for fibrous connective tissue which is an essential component of the

    There are many different diseases that can affect our skeletal system and Osteoporosis is one of them. Osteoporosis lessens bone strength and bone density (amount of bone mineral in bone tissue), which will lead to fragile bones. It mainly affect the hips, ribs, spine, and wrists. Male or female, at any age, can get this but it is mostly occurs in older women (Team, 2016). Osteoporosis is very common, there are more than 3 million cases a year. There are many causes/risk factors, symptoms, and some treatment cases. About 54 million Americans have Osteoporosis and low bone mass (Foundation, 2016).

    Now, when considering whether one wants to prevent or treat Osteoporosis, it does not mean cutting yourself off from foods with small portions or extreme dieting. It is a common misconception that when a person wants to be healthy they must eat in smaller portions, and while this does have some truth, one must consider when it comes to eating healthy, it means to eat healthy by adding nutritious portions of fruits, vegetables, protein, carbs, and of course, calcium intake for the bones in one’s diet. Also, one must not deprive themselves of having a “cheat day” once a week with chips and candy. But it is a good start to begin adding calcium to fortified foods and supplements, such as milk. People should at least aim for 1,000 to 1,200 milligrams a day of calcium.

  • Causes Of Osteoporosis

    1125 Words  | 3 Pages

    Osteoporosis is a serious disease that leads to a faster than normal loss of the bone density, which puts the bone at a higher risk for fractures. In order to understand the causes of Osteoporosis, it is important to understand how bones are formed. Bone is a living tissue that is made mainly of collagen, calcium phosphate, and calcium carbonate. The mixture of collagen and calcium gives the bone strength and flexibility. The body deposits new bones and removes old ones; moreover, there are two types of bone cells that control the reproduction of bones. Cells called osteoclasts breakdown bone tissues thus, damaging the bone. Once the damaged bone is removed, cells called osteoblasts, use minerals including calcium and phosphate from the blood stream to make new healthy bone tissues. In order for osteoblasts and osteoclasts to work properly, hormones such us thyroid, estrogen, testosterone, and growth hormones are

There were no differences in the measurements of 25 (OH) D in all groups. About sixty-one percent, fifty-four children, had concentrations of less than 20ng⁄mL. This is the minimum concentration recommended by the American Academy of Pediatrics to ensure good bone health. These children could be at risk for problems associated with vitamin D deficiency. This includes concerns with bone health and calcium and phosphorus metabolism. Children with autism spectrum disorder are limited to what activities they can do and usually are not exposed to much sunlight causing them to be at a greater risk. Understanding the needs and taking preventive measures for children with autism will help reduce the risk of health problems as they enter adulthood.

  • Essay On Doctors Of Osteopathy

    The big picture. Where the two schools of medicine differ is in philosophy. Doctors of osteopathy "treat people, not just symptoms," says Karen Nichols, dean of the Chicago College of Osteopathic Medicine. "The course list looks exactly the same, but the M.D.'s focus is on discrete organs. The osteopathic focus is that all of those pieces are interrelated. You can't affect one with out affecting another." That means paying more than simple lip service to the idea of the "whole" patient: It means that diagnosis and treatment rely on an examination of a person's environment and family and general situation as well as his or her body. Not surprisingly, about 65 percent of the nation's 52,000 licensed osteopaths (by comparison, the country boasts at least 900,000 M.D.'s) are primary-care physicians. The American Association of Colleges of Osteopathic Medicine has a description of osteopathic training, as well as short profiles of 20 schools, at www.aacom.org. The D.O. programs and their contact information are listed in the directory section of this book.

    Osteoporosis is the loss of bone mass and deterioration of bone matrix resulting in brittle and fragile bones (Weber & Kelley, 2014). The rate of bone resorption is greater than the rate of bone formation, therefore, causing bones to become porous and under stress, can fracture (Drake, Clarke, & Lewiecki, 2015). Conditions that contribute to osteoporosis include poor nutrition, menopause, long-term use of glucocorticoid therapy, and hyperthyroidism are only a few conditions. These conditions all have several related factors that contribute to osteoporosis, breakdown of bone or prevention of bone remodeling. For instance, inadequate dietary intake of vitamin D and calcium can lead to osteoporosis because they are necessary for bone

    The skeletal system is composed of two hundred and six bones in the human body. Functions such as the tendons, cartilage, and ligaments connect the bones and tissues together. Bone tissues make up about 18% of the weight of the human body. There are two types of tissue inside the bones. They consist of; compact bone and spongy bone. First, compact bone depicts the main shaft of long bones in the human body such as the arms and legs. Its tissue is dense and hard and it also makes up the outer layer of most bones in our body. Meanwhile, spongy bone tissue is made up of smaller plates occupied with red bone marrow. Mostly, it is found at the ends of long bones such as the head of the femur.

    Nutrition plays a significant role in the development of osteoporosis. Osteoporosis is a medical condition in which the bones become brittle and fragile from the loss of bone mass which can be the result of hormonal changes or a deficiency of calcium or vitamin D. Calcium is important for healthy bones and because our body does not produce calcium. We must get it from foods that we eat. The needed amount of calcium for adults over 50 years old is 1,200 mg while an age 19-50 is 1,000 mg and for children 9-18 is 1,300 mg. Popular sources of calcium are milk, yogurt and cheese. Other sources of calcium can be found in leafy green vegetables such as lettuces, spinach, collards, kale, Swiss chard, rhubarb, turnip greens, mustard, and

    Osteoporosis is a disease in which the bones become so weak and brittle that even a cough can cause enough stress on the bone that it will cause the bone to facture. The most commonly broken bones are the hip, wrist, and the spine. Although it affects men and women of all races, post-menopausal Caucasian and Asian women are more commonly affected than those of other ethnicities and sexes. In fact, thirty percent of all post-menopausal women in the US and Europe will be diagnosed with Osteoporosis and at least 40 percent of those will suffer from a fracture in their lifetime.
