Horizontal Fibers of the PDL
Horizontal principal fibers (A) are seen in this field. Note they pass horizontally from cementum (B) to the alveolar bone (C) just below its crest. This initial group of horizontal fibers was once referred to as "cervical fibers". Note that Sharpey's fibers (D) can be seen inseerting into the cemntum on the right, and the alveolar bone on the left.
