How to Keep Your Skeletal System Healthy
Bones also contain a complex network of canals, blood vessels, and nerves that allow for nutrient transport and communication with other organ systems. Although bone tissue may look inactive at first glance, at the microscopic level you will find that bones are continuously breaking down and reforming. While bones are hard, they can be broken and weakened if not cared for properly. Calcium It's widely known that consuming dairy products like yogurt and cheese is good for your skeleton. The longest bone in your body is the femur thigh bone , which extends from your hip to your knee. Being vegetarian does not heighten their fracture risk, for the reason that they are still consuming adequate amounts. Trabecular bone is 50 to 90 percent porous and appears as a lattice-like structure under the microscope.

Nutrition's Impact on the Skeletal System

Foods with vitamin D include dairy, eggs, fatty fish such as salmon or tuna and fortified orange juice and cereal. Exposure to the sun triggers vitamin D synthesis to produce vitamin D, as well.

Perform at least 30 minutes of weight-bearing exercise at least twice a week. Building muscle increases bone density to build healthy bones and prevent osteoporosis. You don't necessarily need weights or equipment to build muscle.

Pushups, squats and planks strengthen muscles over most of the body. As you get stronger, using dumbbells increases the resistance to maintain your strength. Avoid smoking and drinking. Discuss potential side effects of medication with your doctor. Some medicines can weaken bones and increase your risk of osteoporosis. Your doctor will be able to prescribe bone-boosting medication if needed.

Wear your seat belt when driving and a helmet when using a motorcycle. Nutrition is one of the most important aspects of a healthy and osteoporosis-resistant skeletal system. Calcium It's widely known that consuming dairy products like yogurt and cheese is good for your skeleton.

Most of the bony benefits that come from dairy's rich calcium content. As the cement that builds the foundation of your bones, calcium is also needed for other bodily functions like muscle contractions. If you don't get enough from your diet, then your body leeches the calcium stored in your bones. In addition to dairy, good sources of calcium include green leafy vegetables, broccoli and almonds.

Adults should aim for 1, mg of dietary calcium per day. Magnesium More than half of the magnesium stored inside your body is found in your skeletal system. But the Office of Dietary Supplements adds that many people don't reach their daily magnesium target of mg for men and mg for women.

Magnesium is crucial for healthy calcium metabolism. Sources of dietary magnesium include fatty fish, soy, whole grains, yogurt and potatoes. Bones adapt their structure to the forces acting upon them, even in adulthood. This is why exercising, especially when it involves weight-bearing activities, increases bone strength.

The first step in bone remodeling is osteocyte activation. Osteocytes detect changes in mechanical forces, calcium homeostasis, or hormone levels. In the second step, osteoclasts are recruited to the site of the degradation. Osteoclasts are large cells with a highly irregular ruffled membrane.

These cells fuse tightly to the bone and secrete hydrogen ions, which acidify the local environment and dissolve the minerals in the bone tissue matrix.

This process is called bone resorption and resembles pit excavation. Our bodies excavate pits in our bone tissue because bones act as storehouses for calcium and other minerals. Bones supply these minerals to other body tissues as the demand arises.

Bone tissue also remodels when it breaks so that it can repair itself. Moreover, if you decide to train to run a marathon your bones will restructure themselves by remodeling to be better able to sustain the forces of their new function.

After a certain amount of bone is excavated, the osteoclasts begin to die and bone resorption stops. In the third step of bone remodeling, the site is prepared for building. These first three steps take approximately two to three weeks to complete. In the last step of bone remodeling, osteoblasts lay down new osteoid tissue that fills up the cavities that were excavated during the resorption process.

Osteoid is bone matrix tissue that is composed of proteins such as collagen and is not mineralized yet. To make collagen, vitamin C is required. A symptom of vitamin C deficiency known as scurvy is bone pain, which is caused by diminished bone remodeling.

After the osteoid tissue is built up, the bone tissue begins to mineralize. The last step of bone remodeling continues for months, and for a much longer time afterward the mineralized bone is continuously packed in a more dense fashion.

Thus, we can say that bone is a living tissue that continually adapts itself to mechanical stress through the process of remodeling.

For bone tissue to remodel certain nutrients such as calcium, phosphorus, magnesium, fluoride, vitamin D, and vitamin K are required. Bone mineral density BMD is a measurement of the amount of calcified tissue in grams per centimeter squared of bone tissue. BMD can be thought of as the total amount of bone mass in a defined area. When BMD is high, bone strength will be great. Similar to measuring blood pressure to predict the risk of stroke, a BMD measurement can help predict the risk of bone fracture.

During this procedure, a person lies on their back and a DEXA scanner passes two X-ray beams through their body. The amount of X-ray energy that passes through the bone is measured for both beams. The total amount of the X-ray energy that passes through a person varies depending on their bone thickness. Using this information and a defined area of bone, the amount of calcified tissue in grams per unit area cm2 is calculated.
