Bone growth

• What is bone classified as in the body?

  A living organ
• What is ossification?

  The process of bone formation and growth
• What happens to parts of the bone during ossification?

  They are reabsorbed to remove unnecessary calcium
• What are osteoclasts responsible for?

  Removing unnecessary calcium from bones
• What is the role of osteoblasts?

  Creating bone matter and bringing calcium
• What are the functions of osteoblasts?

  • Make new bone
  • Synthesize protein and collagen
  • Bring calcium into the bone
  • Activity increases during exercise
• What do osteoclasts do to bone tissue?

  They break down bone tissue
• How do osteoclasts help regulate blood calcium?

  By breaking down bone protein
• What is the balance maintained by osteoclasts and osteoblasts?

  • Osteoclasts clears away old bone
  • Osteoblasts build new bone
  • Balance between bone resorption and formation
• What are epiphyseal plates?

  Growth areas at the ends of long bones
• What is the function of epiphyseal plates?

  Allow bones to grow longer
• When do epiphyseal plates stop functioning?

  When bones reach full maturity
• What happens to the epiphyseal plate when a long bone is fully formed?

  It fuses with the main shaft
• What are the stages of bone maturity?

  • Immature bone
  • Growing bone
  • Mature bone
• What are the two main parts of a long bone mentioned?

  Diaphysis and epiphysis
• What is the diaphysis of a long bone?

  The main shaft of the bone
• What is the epiphysis of a long bone?

  The end part of the bone
• What is the term for the line formed when a long bone is fully formed?

  Epiphyseal line
• What does the epiphyseal line indicate?

  The bone has reached full maturity
