Bone Formation and Growth

Understanding how bone tissue is formed and maintained is central to us understanding how bones can be affected or changed throughout one's lifetime.The objective of this lesson is to identify the key cells stages, and structures of bone formation and repair.

You will be completing some reading and annotating from our online textbook, as well as watching a video and answering some questions.
Question 1
1.

First, log in to our Chapter 6.4 of our online textbook.

Before you start doing any reading, skim through the reading. Look briefly at the diagrams and headers for each section.

What are you the most interested to learn about?

Question 2
2.

Now, read and highlight / annotate section 6.4 (remember: you must be logged in to do this!)

When you are done reading and annotating, click on 'my highlights'. Select only your notes for Chapter 6, like this:


Take a screenshot of your notes and upload it below.

If you do not know how to do this, research 'how to take a screenshot' with your specific computer

Next, watch the video below. Compare your learning from the text with what is outlined in the clip:

Are all bones formed by the same process? Explain your answer.

Question 7

List two things that you found interesting from today's activity

Question 8
8.

What is something concerning bone formation and growth that you are still struggling to understand?

Match the following 'osteo' terms with the best description.
osteocyte
bone development, hardening
osteoclast
cells that help to make new bone tissue
ossification
cells that destroy bone tissue
osteoblast
uncalcified matrix
osteoid
general term for bone cell
Cartilage tissue repairs faster than most other tissues.
True
False
The diagram below is similar to Figure 6.17 from the reading. It outlines the steps of long bone formation from the fetal stage to childhood.


Use the diagram to put the following stages / phases in order.
Spongy bone and blood vessels starts to form in the center of the diaphysis of the bone
Cartilage begins to break down in the center of the diaphysis of the bone
The hyaline cartilage in the epiphyses of the bone is fully replaced with bone tissue
Bone tissue begins to form in the epiphyses of the bone
Bone is made primarily of hyaline cartilage.
