High Power of Cementum
In this ground section dentin (A) lies in the upper left corner of the field. Tomes' granular layer (B) lies just outside this. What type of cementum (D) lies next to the dentin? (look at D to check your answer). Secondary (cellular) cementum (C) overlies the primary cementum layer. Note the tiny fibrous channels, or canaliculi (E), that radiate from each lacuna (F). Cementocytes live in the lacunae of cementum, the canaliculi occupied by their cytoplasmic processes that radiate in the direction of the blood supply. Cementocytes are nourished by diffusion.
