Bone Definition - What it is, Meaning and Concept

The term oseo , with etymological origin in Latin osseus , is an adjective that names what belongs or is linked to bones .A bone , meanwhile, is a piece of great hardness that makes up the skeleton of a living being class (the so-called vertebrates ).

The most important component of the bones is the bone tissue , formed by various cells and an extracellular matrix subjected to calcification.Bone tissue confers the hardness and firmness that characterize the bones.

Three types of specialized cells form the bones: the osteoclasts (which discard or reabsorb the bone tissue), the osteoblasts (boost the bone tissue development) and the osteocitos (name that osteoblasts receive when they reach maturity and change their function).

It is likely that a person suffer a blow or impact that affects the bones.In this sense, a bone trauma is an injury that occurs in a bone.It may be an incomplete or complete fracture, depending on the severity.Bone fracture occurs when the bone loses continuity: if the bone that breaks produces a wound in the skin and comes to the surface, it is spoken of exposed fracture .

The bone cancer , on the other hand, is the one that affects the bones.It is usually a cancer that arose in another region of the organism and that expanded until reaching the bone.There is, however, the primary bone cancer, which arises in the bone itself.

Bones are solid structures that are mainly composed of bone tissue, and these make up the so-called bone system.Internal skeletons are rigid or semi-rigid structures that are found inside a body and are they move thanks to the action of a muscular system.In the case of humans and some mammals, these structures are ossified or mineralized and, therefore, are called bones.

The cartilages are also important components of the skeletal system as they complement their structure.The nose and ears of human beings take advantage of the cartilage in different ways.It should be mentioned that some organisms do not have bone in their skeletons, but consist exclusively of cartilage; sharks are a clear example of this.To connect the bones with the rest of the rigid structures there are ligaments; The union with the muscular system is achieved by tendons.

The skeleton performs several important functions, some of which are:

* Hold : This system of bones or cartilage allows us to support and fix the rest of the parts of the body , but also keep muscles, ligaments and tendons in position , since these lack stiffness or solidity;

* Locomotion : Although the movement could not occur without the help of the muscles, the bone system is an essential part of the displacement, since it serves to keep the body firm and structured;

* Hematopoiesis : In the red marrow of the long bones it has the production of red blood cells and, to a lesser extent, lymphocytes and monocytes;

* Protection : given their solidity, the bones prevent the organs behind them from undergoing significant damage when the body goes through situations such as a fall to the ground, a blow with another solid body or an attack of another living being.Some examples of this function are the brain, which takes refuge perfectly inside the skull; the lungs and the heart, which receive protection from the ribs and spine; the eyes, which are comfortably located in the orbital cavities; the ear, lodged in the temporal bone; the spinal cord, which acts within the spine.
