Bone Basics

To gain the most from this program, it’s important that you have a foundational knowledge of the components of bone and osteoporosis. In this module we will define key words that will be used frequently through out this course. Use the Bone Basics workbook content as a tool to refer back to as you progress though the modules.


This conversation provides an introduction to the different cells that make bone, what stimulates them, and what suppresses them. The goal is to understand the basics of bone metabolism as a foundation for managing osteoporosis. The conversation covers osteoblasts, osteoclasts, and osteocytes, which are the cells involved in building and breaking down bone. It also discusses the different types of bone and the importance of balancing bone metabolism. The conversation emphasizes the importance of early screening and intervention to slow down bone loss and build bone.

Terms Covered in this Module: 

  • Osteoporosis
  • Osteopenia
  • Osteoblasts
  • Osteoclasts
  • Osteocytes

  • Bone metabolism is a balancing act between osteoblasts and osteoclasts.
  • Osteoblasts are cells that build bone, while osteoclasts are cells that break down bone.
  • Osteocytes are mature osteoblasts that play a role in bone metabolism.
  • There are different types of bone, including cortical bone and trabecular bone.
