The cells that participate in the formation of teeth come from two different sources. Odontoblasts, the dentin-producing cell type, derive from mesenchymal cells. Ameloblasts, the enamel-forming cells, derive from epithelial sources. Odontoblasts not only share a common cell type origin with osteo...
The side pawl 402 has an annular body 402A, one side of which has one or more gearteeth 402B. Said one or more gearteeth 402B correspond to the side gearwheel 401, and can occlude with each other or slide freely. When the front wheel 31 rolls forward, said one or more gearteeth ...
