What Are the Divisions of the Skeletal System?

Skeletal system is one of the organ systems of vertebrates. Including the body's various bones, joints and ligaments. Derived from the proliferation and differentiation of mesenchymal cells derived from mesoderm. It has the functions of supporting the body, protecting important organs in the body, attaching muscles, and acting as a lever for exercise. Some bones also have functions of making blood and maintaining mineral balance. According to different parts, the skeletal system is divided into two parts: the axial bone and the appendage bone. Arthropods in invertebrates have chitinous exoskeleton, which functions similarly to the vertebrate skeletal system. ^[1]

Bones are made up

The skeletal system is usually divided into three types-

The main function of bones is to maintain shape. Therefore, the skeleton of marine life is inferior to that of land animals because the ocean provides buoyant support. As animals evolved and moved to land, they began to form solid bone structures. On the other hand, the bones also provide a muscle-connecting surface that assists the muscles to move through the joints. The bones also provide protection for the internal soft tissue structure. The exoskeleton wraps the entire body and contains all the organs. It has a high degree of protection, but it is inconvenient to move and limits the size of the organism, so it is only found in lower organisms. Higher organisms have endoskeletons, which are less protective than exoskeleton, but can also protect some important organs, such as the brain, spinal cord, and

Bone protection from an early age

During the development of a child, the major parts of the body's bones are most easily deformed. This is like a metaphor of the image of a technician at the Spanish headquarters: "How is the Chinese bonsai created, that is, the shape of the plant is fixed by the iron wire during the young period And formed. Therefore, we need to pay attention to our children's bone health from an early age.

Get enough calcium

99% of the calcium in the body is stored in bones and teeth, which support your body; the other 1% is in the blood. This 1% also plays a very important role, such as controlling muscle contraction, blood clotting, Hormones are secreted, these are very important for life. And if your diet doesn't have enough calcium, your body needs to draw a "stock" of calcium from your bones to maintain the calcium content in your blood. Over time, this scarcity has led to loose bones. In fact, the daily diet is the best calcium supplement channel. A cup of milk or yogurt contains 300 mg of calcium. Drinking 3 cups a day is enough. Some green leafy vegetables, such as kale, are also rich in calcium, as are soy milk and high-calcium drinks.

Choose the right exercise

In theory, all sports are good for health, but not all sports are equally effective at improving bone health. It's best to choose weight-bearing exercises such as walking, dancing, jogging, climbing stairs, or lifting weights. Because when you jump, run, or lift weights, your bones are under stress, and your body receives a signal that you need to strengthen your bones and start making new cells to strengthen your bones. However, in childhood with weak bones and the second growth spurt, weight-bearing exercise should be moderate, otherwise it will easily affect the growth of height.

Eat more foods containing vitamin D

Vitamin D works like a calcium stabilizer, it helps us absorb calcium from food and locks it into our bones. There are two sources of vitamin D: the sun, UV rays interact with the chemical components in the skin to produce vitamin D; foods, including egg yolk, salmon, tuna, animal liver and other foods contain vitamin D.
