A Framework for Success

The Skeletal System Design, Function and Imbalance

The Big Picture:
Keep the following understandings in mind as we move through the unit
  • The skeleton is a dynamic, constantly changing framework for the body
  • The components parts of the skeleton are all specifically designed to suit their function and create a structure greater then the sum of its parts
  • Homeostatic imbalance leads to an intrinsic failure in the system

Essential Questions
You will be asked to answer the following questions during or at the end of the unit.
1. How can we improve on the design of the skeleton?
2. How does the position of bones on the skeleton determine their function?
3. Is the least invasive method of treating various bone disorders necessarily the best?

What you will need to be able to do by the end
At the end of this unit you should be proficient in the following list of objectives. Check them off as you feel confident you have learned the content necessary to complete them. Proficiency will allow you to use the information to complete various assessments along the way

6. Distinguish between osteoblast, osteoclast and osteocyte function and describe the mechanism of bone remodeling
7. Relate the structure of long bone to its function
8. Identify and describe the various types of bone fractures
9. Describe the stages of bone healing

Axial Skeleton
10. Identify and name the bones of the skull
11. Compare and contrast the fetal and adult skulls and explain the role of the fontanels
