Tomes' Processes
This electron micrograph shows recently deposited, immature enamel (A) and that part of the ameloblast that secretes it - the Tomes' processes (B) projecting into it. Rough ER fills the lower ends of the ameloblasts above the level of the terminal bars. Rough ER produces the organic matrix of enamel. Secretory granules fill the Tomes' processes. Ameloblasts secrete in a merocrine fashion.
