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
Skeletal System Overview

2. Describe the functions of the skeletal system
3. Identify and classify different types of bone
4. Describe some common bone markings
5. Research a named bone and design an information sheet on the bone
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
12. Identify and distinguish between bones from the different vertebral regions
13. Explain how and why bones from different vertebral regions are structured differently
14. Explain how a spinal tap used to diagnose spinal cord and brain imbalances
15. Compare different spinal abnormalities
16. Explain how the structure of the ribs and sternum enables the functioning of the thoracic cavity

Appendicular skeleton
17. Explain the difference between the male and female pelvis
18. Describe the bones of the appendicular skeleton

Joints/Articulations

Homeostatic Imbalance
22. Relate the causes of arthritis, osteoarthritis and gout to an intrinsic failure of a system
23. Explain the invasive, and noninvasive, treatments of skeletal and bone disorders
