Tooth
The junction of the enamel (left) and dentin (right) is shown in this section of ground tooth. The dentin is formed and maintained throughout life by odontoblasts that lie in the pulp cavity adjacent to the dentin. Odontoblasts secrete matrix, investing their processes in dentinal tubules, which span the thickness of the dentin. 200x
