Skeletal System

The human skeletal system performs a number of key functions in the human body. The key functions of the human skeletal system are:

  • Support: Our bones provide the rigidity we need to function.
  • Protection: The rigidity of our bones allows them to protect our internal organs from damage for example the rib cage and the skull.
  • Movement: Without the strength of our bones we wouldnt be able to move our muscles are anchored to our bones.
  • Storage: Our bones are a storehouse for fat and certain essential minerals.
  • Blood cell formation: Most of our blood components are made in the bones.


The appendicular bones are found in the arms and legs, and attach, or append, to the body.
