7.3 Bone Development and Growth
1. When does the formation of the skeletal system begin to grow and finish growing and developing?
2. Differentiate between the formation of two types of bones:
Intramembranous bones:
Endochondral bones:
3. Define the following terms:
Osteoblasts:
Osteoclasts:
Epiphyseal Plate:
4. What can happen when the epiphyseal plate is damaged before it ossifies? (Look in grey box on page 129)
5. How do osteoclasts, osteoblasts, and hormones help with homeostasis of bon tissue?
7.4 Bone Function – Not every section has questions but you are responsible for reading them all.
6. Describe the 4 basic components of a lever.
7. What is hematopoiesis happen in children and adults?
8. Differentiate between the two types of marrow.
9. Why is blood red?
10. Explain how the parathyroid and bone tissue cells help to regulate your blood calcium levels.
11. What is calcium used for in the human body?
7.5 Skeletal Organization
1. List the parts of the axial skeleton.
2. List the parts of the appendicular skeleton
3. Label the major bones of the axial and appendicular skeleton. Then color the axial skeleton bones red, and the
appendicular bones green. (Use the skeleton on page 134 and add the hyoid bone, calcaneus on pg. 154, and the parts
of the vertebrae on pg. 142)
