Example of Human Body Bones

The bones of the human body or osseous system It is the one in charge of the support and motor functioning of the body and in the case of humans it is formed per approximately 206 bones (this may vary in children who have split bones that fuse at the grow up).

There are many divisions that have been made according to their size and function:

• Short
• Long and
• Blueprints.

Due to their training, they are divided into:

• Fluffy fabric
• Nutritive adipose tissue and
• Hard tissue

Bones have a posterior division called skeletal regions. The one that is separated into:

• Axial function bones
• Appendicular function bones
  

The bones of the body are:

The first of the divisions of the bones found as follows:

Short bones

They are found in small units such as the spinal column, the wrists, and the mass of the heels. (ankles), including the bones of the ears and some of the bones of the skull (which are fused later).

Long bones

These bones form the motor structure of the body, which although it includes small bones, are part of the extensors, allowing walking and moving the hands.

Flat bones

Flat bones are placed in the body in order to protect organs, the protective function can be seen in the ribs, and the skull.

Bone formation

In their internal structure, bones are made up of:

• Cartilage.- This is a very resistant mass of bone tissue that can be elastic, it also works as a cushion in the joints.
• Bone marrow.- It is a nutritive substance that forms red blood cells or becomes an energy reserve.
• Periosteum.- This is a membrane that covers the bone is very fibrous and resistant, in the region of the ligaments there there is periosteum, this periosteum has blood vessels and nourishes the bone by membranes and blood vessels.
• Tissue.- This has a subdivision because here its structure is reclassified, having the compounds, compact, haversian and spongy.

Fluffy fabric

This tissue is composed of the red bone marrow, where stem cells are found that allow the bone to be repaired and have information genetics, this allows a certain homeostasis that regulates the body in addition to producing red blood cells that pass directly into the stream blood.

Fatty and nutritive tissue

This is an energy reserve in which a very high amount of protein is stored, it appears as a yellow and very dense fat.

This tissue allows the body to store nutrients necessary for growth, sustenance, and formation of blood and red blood cells.

Hard tissue

It forms the base that supports the body, its structure is firm and later it is porous so that the nerves and blood vessels are irrigated and grown.

Compact bone tissue

This tissue is made up of small lamellae, which together form the hard outer part of the bones.

Haversian bone tissue

They form cells similar to those of bees, which allow the passage of vessels, nerves and nutrients.

Functions of bones

Sustenance

The main function is the support, which has the quality of supporting the body, without it we would be a mass to form or an exoskeleton would have developed as happens with insects.

Movement

They allow movements, because by inserting the muscles in the legs, hands and various parts of the body they allow them to be stimulated and movement occurs.

Increase

Growth is divided into two parts

• Throughout.- This is done in the metaphysis, which has growth cartilage.
• In thickness.- In the periosteum, new bone membranes are formed and repaired in case of rupture or damage.
