The Structural System
The Bones, Muscles, & Connective Tissue

The Structural SystemFramework for the Body

In a city, we see buildings in various phases of construction. Some have only the foundation. Others have the girders in place. And some are completely finished, so that we can?t see the internal framework. But we know it's there; otherwise, the building couldn?t stand. Our own structural system is no different.

Our structural system consists of bones, muscles, and connective tissue. This system is what gives our body form and the ability to move about. Without it, the body would collapse under its own weight.

The structural system also houses all the other systems of the body and protects them from the outside environment.

The skeleton accounts for only 14 percent of body weight and is made up of 206 bones. The skull is the most protective mechanism in the body. It is supported by the spine, which stands the stresses of bending and stretching while supporting body weight. The skeleton is also the foundation for the muscles.

BonesThe muscles comprise about 40 percent of body weight. They convert chemical energy into force and mechanical work. Movement is one of the main functions performed by 620 muscles in the body. They also help maintain proper posture and produce a large portion of body heat.

There are 30 other muscles that perform functions such as moving food through the digestive system, circulating blood, and operating other internal organs.

Connective tissue consists of ligaments and tendons which connect muscles and bones.

Factors in Structural Health

Calcium is the most abundant mineral in the body, comprising 1.5-2 percent of an adult's body weight. But calcium deficiency in the U.S. is not as rare as might be expected in a modern nation. The Department of Agriculture lists calcium as one of the four nutrients most missing in the American diet.

The body is constantly using calcium from the diet to replace old bone tissue with new tissue. When the calcium supply in the blood is low the body takes calcium from the bones without replacing it, causing them to become weak and porous.

A growing health concern is bones that become weak and soft from calcium and other deficiencies. Such deficiencies can cause bones to break easily, or leave a person with a stooped and shortened stature. It is estimated that 5 million women and 1 million men exhibit some effect of calcium loss from their bones.

Bone loss appears to begin about age 35 and is of special concern to women. Lack of exercise and decreased secretion of the hormone estrogen after menopause have been related to calcium loss. A calcium loss is only visible in X-rays after the loss is acute. It is estimated that up to 60 percent of the mineral content of bone may be gone before the loss can be detected.

Physical activity helps to increase bone volume and density. Weight control can also take some strain off bones and muscles so they can perform better. Of course, the structural system requires a balanced diet with a healthy supply of minerals.

Calcium Plus Vitamin D Calcium Plus Vitamin D supplies nutrients required for both the structural and nervous systems. Derived from bone meal and combined with other trace minerals needed by the body, NSP Calcium more easily enters the body to help replenish bone tissue that is constantly being replaced. Calcium comprises half of all the minerals in the body, but this still only represents 2 percent of the body's entire weight.

This formula also contains phosphorus, the second most abundant mineral in the body. It works with calcium, and both are commonly found in nature. This formulation provides calcium and phosphorus at a 2:l ratio.

Magnesium is also added in the same 2:1 ratio with calcium. Without these important ratios, the body begins to lose one or more minerals before they can be utilized. Calcium is needed by the immune system. It is also critical to muscle contractions. Phosphorus works synergistically with B vitamins to help maintain a proper fluid balance in the body. Magnesium, often lacking in Western diets, assists in calcium's proper function.

Vitamin D is added to help calcium do its job. At least 400 IU of vitamin D is needed on a daily basis, especially for those not getting enough sunshine (D is the 'sunshine vitamin?).
