Guest OogaLooga Posted June 27, 2003 Share Posted June 27, 2003 Why teeth are not considered as bones? Can anyone give me a good explanation on that? Link to comment Share on other sites More sharing options...
Skye Posted June 27, 2003 Share Posted June 27, 2003 Teeth develop from different parts of the embryo to bone during development. The outer layer of teeth, the enamel, is derived from cells, that in the early stages are called the ectoderm, and that also go onto to form organs such as the skin. The inner supporting dentin of teeth is derived from the neural plate, which goes onto to form the nervous system. http://www.biology.ualberta.ca/courses.hp/zoo.225/OL06-08.html Link to comment Share on other sites More sharing options...
