What are the bones for?

In this article I will tell you about what is neededbones to humans and other mammals. We will consider the basic functions of bones, and also touch on the question of maintaining bone health, because it directly depends on how the bones will perform their functions, helping a person to live a full life.

Basic functions of human bones

The most important functions of bones arethe following. First, they protect our body from the inside, for example, the ribs or skull bones protect various soft internal organs - the heart, lungs and brain, respectively. These organs are arranged too thinly, and therefore need constant protection. Well, and secondly, the bones form a skeleton, to which the muscles and ligaments are attached. Without bones, a person simply could not move and would remain completely still. Bones are the main link between the brain and muscles - that is, the beginning and end of the neural chain. If you want, these are original cables, inside which there are various impulses necessary for the well-coordinated work of all body systems. Therefore, bones are a very important organ in the human body. Thus, the first function of bones is protective, and the second - motor or mechanical. However, this is not all. In addition to mechanical functions (protection of internal organs, maintaining the shape of the body, providing the possibility of movement), the bones also perform biological functions, for example, the hematopoietic. It is in the bone marrow that new blood cells form. Well, besides, bones are the storehouse of almost all phosphorus and calcium in the body, and therefore, are important for the exchange of minerals, which is also a biological process. And now we will tell you about the functions of bones in more detail, and then we'll talk how to ensure the preservation of these functions.

What are bones used for?

Bones are the main constituent of bonesystem and perform in the body both mechanical and biological functions. The first, as we have said, include the functions of support and movement of the body, as well as the protection of individual organs and organ systems from various external injuries and injuries. Thus, the brain is protected by the bones of the skull, and the spinal cord - by the spine, inside which it is located, the lungs and the heart are reliably protected by the thorax. Movement of the body is carried out with the help of so-called movement organs, which include bones, muscles and joints of bones - mainly joints. And the biological function of bones is, mainly, their participation in all possible metabolic processes, since they contain the bulk of all the mineral substances of the human body. These are calcium salts, and phosphorus, and magnesium with salts and other elements and substances. Red bone marrow is the main source of elements (cellular) blood. In the process of life, the bones undergo significant changes. At the fetus they are almost completely cartilaginous, and only then their gradual ossification occurs. In children, bones contain much more organic substances than adults, and with age, the strength of bones decreases. In childhood, bones grow together with various injuries much faster.

Dysfunction of human bones

Development of bones and metabolic processes occurunder the influence of the nervous, as well as endocrine systems of the body. Physical exercise is also important for the normal functioning of bones. Long-term immobilization leads to a significant decrease in the mechanical strength of bones. Proper nutrition is also essential in the formation of bones. For example, the lack of vitamins often leads to various bone deformities and lag in growth, and deficiency of phosphorus and calcium salts can lead to increased fragility of bones and their bending. Very often, with bone diseases, all sorts of deformities and pain can occur. Often this is preceded by a disproportionately heavy physical load. And here it is very important not to aggravate the patient's condition by improper actions, and if there is pain in the bones, it is necessary to unload the corresponding part of the skeleton, that is, to create conditions for maximum rest. For example, with pain in the shoulder, it is good to hang the hand on the kerchief, and with pain in the leg - to restrict walking and standing on the legs. While maintaining the same pain, it is better to use a cane. Suddenly, the appearance of deformity of the bone is treated like this: on the curved part of the limb, a tire is placed to immobilize, without trying to straighten it. Most often, the cause for first aid for various bone injuries are dislocations and fractures. Bones are a vital organ in our body, performing a lot of not just useful, but extremely necessary functions, so you need to protect the bones as carefully as possible and, if possible, prevent injuries and diseases.
