Figure 2 in Some data on the histological organization of bony tissues and teeth in the Mackerel, Scomber scombrus L. 1758 (Acanthopterygii, Perciformes, Scombridae)

Figure 2. – Scomber scombrus. Details of the bony tissue showing the lack of osteocytes in the vertebra and in the dentary. A: MNHNF-Histos 1964. Vertebral bony tissue showing primary pseudolamellar bone (PB). Osteocytes lacunae are absent. B: MNHNF-Histos 1953. Dentary bony tissue near the caniniform tooth of Fig. 5. The main vascular cavity (VC) is surrounded by a layer of secondary bone (SB) separated from the primary bone (PB) by a reversal cementing line (black arrowheads). The black arrows point to relatively thin ramified vascular canals. C: MNHN-F-Histos 1953. Detail of the dentary wall showing primary pseudo-lamellar bone (PLB) crossed by thin vascular canals (black arrows). Osteocytes are absent. VC: vascular cavities. Scale bars: A = 50 μm; B, C = 100 μm.
