HISTOLOGY OF THE DENTAL TISSUES. 55 a single process, but during the active stage of development the cells areflat and broad, or truncated at the end directed towards the forming dentin(Fig. 170). During this period the odontoblasts often present two or moreprocesses ; Boll has counted no less than six, proceeding from a single cell possesses a single ovoid nucleus, which is located in the end ofthe cell nearest to the dentinal papilla (Fig. 171). The nucleus is some-times pointed at the extremity nearest the forming dentin. The body ofthe cell is finely granular, and Waldeyer and Boll both found the celldestitute of any semblance of membrane. The processes of the cells passinto the dentinal tubuli, and constitute the dentinal fibrils. Stowell (1887) says there are three separate forms of processes arisingfrom each odontoblast: first, those that unit
