However cartilage in osteoarthritis, located at the ends of the bones erodes and deteriorates, causing friction and hence pain, swelling and restricted movement. Therefore in osteoarthritic both the composition and appearance of the cartilage alters, while the body attempts to repair this damaged cartilage is broken down faster than it can be built up. A defective repair process can cause bone overgrowth, bone spur/osteocytes to form which can be seen at the ends of the joints. In osteoarthritis the bones come in close contact with each other, and wear away leaving the bone exposed and unprotected. Question 2: a) What are the signs or symptoms of ost... ... middle of paper ... ...e: stimulates the growth of bones.
Osteoporosis is the loss of bone mass that results in the bones thinning. The thinning of the bones causes them to be very weak, fragile and they are susceptible to fractures and breaks easily. Osteoporosis mostly affects the skeletal system because it’s made up of bones, but it impacts other systems in the body indirectly. Osteoporosis can result if the body does not produce enough bone cell through Ossification or if the body losses or destroys a lot of bone cells. This means when suffering from Osteoporosis, there is the presence of fully formed and Calcified Osteons, but there is a deficiency which creates empty space in the bone tissue making it brittle.
Osteoporosis occurs when the holes between bone become bigger, making it fragile and liable to break easily. Osteoporosis usually affects the whole skeleton but it most commonly causes breaks or fractures to bone in the wrist, spine and hip. Women are potentially at higher risk of osteoporosis because of the bone loss that occurs when they get relatively old and are experiencing menopause. (Men can, however, acquire the bone disease as well.) The low estrogen level results in an accelerated bone loss.
The breakdown of these tissues would lead to the joint pain and the joint stiffness eventually. In addition, it also affects both the larger and smaller joints of the body, but it particularly affects the weight-bearing joints that get heavy use such as hips, knees, the spine, the base of the thumb and the big toe joint. Osteoarthritis is essentially caused by the daily wear and tear of the joint as well as the result of injury or damage to the joints, for example a fracture or previous inflammation in that joint. Osteoarthritis has three main characteristics. Firstly, the development of the bony growths around the edge of joints.
They develop as masses of hyaline cartilage 3. Eventually the cartilage decompses forming periosteum from connective tissue that encircles that developing structure 4. Blood vessels and undifferentiated connective tissue cells invade the disintegrating tissue 5. Some of these cells become osteoblasts 6. Ostoeblasts form the spongy bone in the spaces previously housed by cartilage 7.
Osteoporosis attributes a decrease in bone strength due to the degeneration of bone tissue and mineral loss amongst a variety of individuals who hold different risk factors. This bone ailment has been linked to causing height loss, chronic pain, and difficulty with normal daily activities (Poole and Compston, 2006). The most prevalent cause of Osteoporosis is age related, as bodily processes tend to wither away and bone regeneration become... ... middle of paper ... ...neral Research, 20(5), 886-892. doi:10.1359/jbmr.2005.20.5.886 Pierre, M.

The age-related change that I am most concerned about developing is osteoporosis. The bones in our bodies are living tissue, and there is an ongoing process of replacement and reabsorption. When this process is interrupted in a way that the new bone doesn’t keep up with removing the old bone, osteoporosis can happen. Studies tell us that men and women are affected, but Caucasian and Asian women who are post menopause are at a higher risk of developing this bone disease. It causes bones to be brittle and weak so that even a small fall will cause a fracture.
When this happens to your bones, they become weak and you will have an increased risk of breaks or fractures. People with osteoporosis most often break their hip, spine, and wrist bones. There are numerous risk factors attached to osteoporosis. The first risk factor would be age. After the age of 30 your body slowly begins to lose bone mass/density.
Progressive bone loss also shrinks your jaw over time. This causes dentures to no longer fit properly. In turn, your dentures develop stress and pressure points causing cracking and breaking so you’ll need denture repairs. Poor fitting dentures cause microfracture formation in your dentures as you chew food. This is worse if your upper and lower dentures don’t align properly.
Disks in our vertebrae gradually lose fluid causing the middle of the body to gradually become shorter. Joints become stiffer and sometimes even painful due to inflammation. Such changes can result in decreased strength or functions affecting most if not all of our other systems. The Cardiovascular System also referred to as The Circulatory System is greatly impacted by age. Blood vessels begin to decrease in elasticity causing stiffness.
