Process of bone growth

Question 1

What is the process of bones being continuously reshaped called?

Answer 1

Remodelling

Question 2

What is the process of bones being formed called ?

Answer 2

Ossification

Question 3

What happens throughout the process of ossification?

Answer 3

Parts of the bone are reabsorbed so that unnecessary calcium is removed while new layers of bone tissue are created.

Question 4

What is the name of the cells that removes unnecessary calcium by reabsorbing parts of bone?

Answer 4

Osteoclasts

Question 5

What is the function of osteoblasts?

Answer 5

They are the cells that bring calcium to your bones and are responsible for creating bone matter.

Question 6

In what situation does osteoblast activity increase? What does this mean?

Answer 6

Osteoblast activity increases when you exercise so your bones will become stronger the more exercise you do.

Question 7

How does exercising reduce the risk of osteoporosis?

Answer 7

Osteoblast activity increases when you exercise so bones become stronger the more you exercise

This means that calcium stores increase to cope with the demand for calcium

This reduces the risk of osteoporosis.

Question 8

What activities can build stronger bones?

Answer 8

Tennis, netball, basketball, aerobics, walking and running

Question 9

How to bones grow longer?

Answer 9

The ends of each long bone contain growing areas - or plates - which allow the bone to grow longer.

Question 10

What period of time do bones grow longer for? What are the plates at the end of each long bone called?

Answer 10

The growth of long bones continues throughout childhood until full maturity is reached.

The plates at the end of each long bone are called epiphyseal plates and they allow for the long bones to extend.

Question 11

How is the epiphyseal line created?

Answer 11

Once a long bone is fully formed, the ‘head’ (end of each bone) fuses with the main shaft (diaphysis) to create the epiphyseal line
