Skeletal system

• he Skeletal System is the body’s central framework.
• Its primary functions include supporting the body, allowing motion, and protecting vital organs
• it is composed of around 300 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together.
• connective tissues are:

  cartilage

  joints

  tendons

  ligaments
• cartilage is a flexible connective tissue, much like bone, but without the calcium phosphate.
• Tendons – connect muscle to bones
• Ligaments – connect bones to bones
• Joints are the areas where 2 or more bones meet. Most joints are mobile, allowing the bones to move. 
• 2 types of skeletons:

  axial skeleton

  appendicular skeleton
• The axial skeleton forms the central axis of the body and consists of the skull, vertebral column, and thoracic cage.
• The appendicular skeleton consists of the pectoral and pelvic girdles, the limb bones, and the bones of the hands and feet.
