The bones are each rigid components that give structure to vertebrate animals. Among these animals are: fish, birds, reptiles, amphibians and mammals. The bones are, in other words, the parts of the skeleton.The skeleton supports and gives physical form to the body of the living being that contains it. Animals that do not have a skeleton instead have an external formation that protects them, such as a shell or shell; It is then about snails and beetles, for example.

What are bones for?

Bones, being formations with a high degree of hardness, have great physical utility in the body of living beings.

The bones serve to:

  • Protect internal organs
  • Body support
  • Provide calcium to industrial processes

Protect internal organs

Bones are responsible for the protection that living vertebrates require. The ribs protect the soft organs, such as the lungs, stomach, liver, pancreas, and kidneys.

They serve as a support for the body

The joined bones form the skeleton, which is the structure that supports the body’s weight and allows mobility. Living vertebrate beings adapt to the terrain they tread and move thanks to bones.

In industry, animal bones are used to supply calcium to industrial processes

In the agro-industrial field, animal bones are ground and used as food for fish, birds, pigs and even cattle, although the use of this alternative in cattle has been prohibited due to the transmission of bovine spongiform encephalopathy , a disease known as the ” mad cow syndrome “.

Calcium from bones is supplied in polymerization processes to make plastics, or to be added to paints.

What are bones made of?

If the bones are deficient in any of its components, they are prone to fracture.

Bones are made up mostly of the chemical element calcium . It contains it as mineral salts, such as tricalcium phosphate Ca 3 (PO 4 ) 2 , in crystalline form; calcium carbonate CaCO 3 , collagen and other substances that work as a reinforcement.

Mineral salts accumulate in microscopic spaces between the collagen fibers, then crystallize and harden in a process called ” calcification .” It is essential that this is carried out correctly during early childhood and in newborns.

The materials that bones are made of are divided into bone tissue and cartilaginous masses . The bones have a soft inner part, which is rich in mature stem cells, which are intended to restructure and repair the bone in case of injury.

In the spinal column there is a soft tissue called bone marrow , in which the central nerve that allows movement and a high amount of the aforementioned stem cells, responsible for bone and blood regeneration, is protected.

The most common disease related to bones is osteoporosis , which is a decalcification of these, generating empty spaces. Its prevention is possible by consuming foods rich in calcium, such as dairy or grains, or by taking nutritional supplements.

Woven bone

Human skeleton is made up of bones

Bones are made up of tissues that are classified according to their physical strength: compact bone tissue or spongy bone tissue .

The compact bone tissue forming the outer layer of all bones of the body and long bones. This type of tissue provides protection and support, and helps long bones withstand the pressure of the weight they bear.

The tissue cancellous bone is fragile, because it is not naturally very hard. It is made up of thin plates of bone called trabeculae . The spaces between the trabeculae of some bones are occupied by the bone marrow , which is responsible for producing blood cells. This type of bone tissue is found on the inside of the bones, while the compact is on the outside, responsible for protection.

Parts of the skeleton

In the human body there are approximately 206 bones, and they give the skeleton two different parts:

  • axial skeleton
  • Appendicular skeleton.

The axial skeleton consists of the skull, facial bones, ribs, sternum, and spinal column.

The appendicular skeleton begins in the scapular area, at the shoulder, through the bones of the upper and lower extremities, and through the pelvic area.
