Turn your bone remodeling notes into a concept map

Upload a PDF, DOCX, PPTX, text notes or a photo of a textbook page. The map breaks the cycle into osteoclasts, osteoblasts, RANKL and hormone control, and you can edit and expand every branch.

How a bone remodeling concept map is structured

Bone remodeling runs as a continuous cycle, so a bone remodeling concept map works best when it links the phases instead of listing them. Start from the center with the cycle itself, then branch into resorption by osteoclasts, reversal, and formation by osteoblasts.

  • Center node: the remodeling cycle, with activation, resorption, reversal, formation and quiescence as the main branches.
  • Cell branches: osteoclasts, osteoblasts and osteocytes, each with its role and what regulates it.
  • Signal branches: RANKL and OPG, PTH, calcitonin and estrogen, linked to the cells they act on.
  • Clinical branch: how imbalance between resorption and formation shows up in conditions such as osteoporosis.
Example bone remodeling concept map branches
Resorption phaseOsteoclasts attach to the bone surface · They dissolve mineral and digest collagen · They leave a resorption pit
Reversal phaseMononuclear cells clear the surface · Signals recruit osteoblast precursors
Formation phaseOsteoblasts lay down osteoid · Osteoid mineralizes into new bone · Some osteoblasts become osteocytes
RANKL and OPGRANKL promotes osteoclast formation · OPG binds RANKL to block it · Their ratio shifts bone turnover
Hormonal controlPTH raises RANKL · Estrogen suppresses osteoclast activity · Calcitonin reduces resorption

Editable branches

Rename, move or add sub-points so the map matches how your instructor framed the cycle.

Drill from the same source

Turn the same material into flashcards or quizzes when you need to practice recall.

How it works

Upload your notes

Add a lecture slide deck, a textbook chapter PDF, or typed notes on bone remodeling.

Review the branches

Check the phases, cell types and hormone links, then edit anything that differs from your course.

Explore and study

Click through the map branch by branch, then quiz yourself on the parts you still mix up.

Hormonal and mechanical signals sit on the outer branches. Parathyroid hormone raises RANKL, estrogen restrains osteoclast activity, and osteocytes sense loading. Keeping these links visible helps you explain why bone turnover changes in different conditions.

Frequently asked questions

What are the main phases of bone remodeling?

Remodeling moves through activation, resorption by osteoclasts, reversal, formation by osteoblasts, and a resting phase. Mapping them as a loop makes it clearer that each phase hands off to the next.

How do RANKL and OPG control bone remodeling?

Osteoblast-lineage cells express RANKL, which drives osteoclast formation, while OPG binds RANKL and blocks that signal. The balance between the two shifts how much bone is resorbed.

Can I export the concept map?

The free plan lets you explore and edit the map in your browser. PDF and DOCX export are included with Plus, which costs $39 per year or $7.99 per month.

Will it work with photos of my textbook pages?

Yes. Photos of pages are read with text recognition, so you can generate a map from a picture of a chapter section.
