Meaning of Bone System

What is Bone System:

The skeletal system is set of bones that make up the framework of the skeleton of an animal.

The human skeletal system, also called the human skeleton, is the living structure of hard bones whose principal function It is the protection and support of the vital organs and the generation of movement or not in the body.

The bones in the skeletal system do not touch, but are held together by muscles, tendons, and ligaments. Tendons attach muscles to bones, and ligaments attach bones to other bones.

Some examples of how the skeletal system protects the organs of the body are:

  • Skull: hard, curved and closed plates, to avoid blows to the brain.
  • Jaws: Support the teeth.
  • Ribs and sternum: protect the heart and lungs.
  • Dorsal spine: made up of vertebrae, protects the spinal cord and serves as the central support for the body.
  • Feet and hands: give flexibility, vigor and movement.

The bones of the skeletal system grow lengthwise (longitudinally) and widthwise (diameter):

  • Long bones grow at their tips with the formation of cartilage which is then replaced by bone until it reaches its final length.
  • The diameter of the bones increases due to the generation of new layers of bone on their surface called osteoclasts. Each new layer thins the inner layers of the bone, creating a porous but rigid consistency that allows blood vessels to circulate and keeps the bones light without losing strength.

Functions of the skeletal system

The skeletal system is a specialized structure that fulfills different functions, some multiple and others specialized, which are important for vertebrate living beings, among which we can mention:

  • Protect organs.
  • Support the muscular structure.
  • Allow motor locomotion.
  • Carry out mineral homeostasis that allows the storage of minerals, such as calcium, necessary to give bones resistance.
  • It allows the production of blood cells through the red bone marrow, from which both red and white blood cells, as well as platelets, are obtained.
  • Fat storage.
