Functions of Skeleton

The human skeleton is living and performs many functions in the body. Some important functions are summarised below:

  1. Movement: muscles attach to the bones of the skeleton, enabling movement.
  2. Protection: the skull protects the brain, the ribcage protects the heart and lungs, and the pelvic bones protect the digestive tract and reproductive organs.
  3. Support: provides shape and support to the body.
  4. Storage of minerals: bones store minerals such as calcium and phosphate ions.
  5. Hearing: bones in the middle ear, called the hammer, anvil and stirrup, amplify sound waves and assist in the hearing process.
  6. Red blood cell production: long bones and flat bones contain red bone marrow to produce red blood cells.
