  • 3. + Functions  Movement – the skeleton provides the structure for muscles to pull against and shorten, creating movement.
  • 4. + - Functions -
  • 5. + Types of bones
  • 6. + Types of bones  Long Bones – have a diaphysis (shaft) and epiphysis (growth plate – the bones of the limbs in particular)  e.g. the bones of the limbs – humerus, radius, ulna, femur, tibia, fibula.  Ribs, Phalanges, Metacarpals and Metatarsals.  The femur is the largest bone in the body.
  • 7. + Types of bones  Short Bones – bones of the hands and feet, i.e. the carpal (hand) and tarsal (foot) bones.  They have no shaft and are as long as they are wide.
  • 8. + Types of bones  Flat Bones – the bones of the skull (excluding the mandible), the ilium (pelvis), and scapula.
  • 9. + Types of bones  Sesamoid Bones –  Bones that are wrapped in tendon or connective tissue  The patella (knee-cap)
  • 10. + Types of bones  Irregular bones – “one of a kind” bones  The spinal column is comprised of 30 irregular bones – no two are exactly the same shape.  7 Cervical 12 Thoracic 5 Lumbar 5 Sacral (fused) Coccyx
