The  Skeletal System                        Introduction

Your Skeletal system is all of the bones in the body and the tissues such as tendons, ligaments and cartilage that connect them. Your teeth are also considered part of your skeletal system but they are not counted as bones. Your teeth are made of enamel and dentin.

Your skeletal system does not work alone. We already mentioned the interaction with your muscular system. Muscles connect to your skeleton and they contract and move the skeleton along. Your skeletal system is made up of cartilage and calcified bone that work together.

Osteoporosis is a prevalent disease of the skeletal system, particularly among the elderly, resulting in the loss of bone tissue. In osteoporosis, bone loses calcium, becomes thinner, and may disappear completely.  Leukemia , this is a cancer of the white blood cells.

  • At birth the human skeleton is made up of around 300 bones. By adulthood, some bones have fused together to end up with 206 bones.
  • Human bones grow continually from birth till our mid 20's. Our skeleton's bone mass is at its maximum density around the age of 30.
  • If broken our bones will re-grow and repair themselves. Often doctors will place a cast on splint to make sure these bones repair straight and true.
  • The longest bone in the human body is the thigh bone called the femur.
  • Calcium is very important for our bones and helps keep them strong and healthy.
