Figure 6 A photomicrograph of a longitudinal section of the zero control group of goat’s mandible, showing the osteoblasts (Ob) as cuboidal to ovoid basophilic cells that constitute a single layer surrounding the surface of the bone trabeculae. Osteocytes (O) are present within their lacuna in the bone trabeculae. Osteoclast (Oc) is a multinucleated cell in shallow depressions called Howship’s lacuna. Hematoxylin and eosin ×400. Notice also the presence of bone marrow (M).
