General features of bone histology in the Anura. (A) Cross-section in the femur of Nanorana vicina (specimen MNHN AC. 1985-1054; transmitted polarized light). The cortical bone is avascular and isotropic in this sectional plane. Conspicuous birefringent lines of arrested growth occur (arrow heads); (B–C) longitudinal section in the femur of Conraua goliath (specimen ZFMK 15885). The bone tissue forming the cortex displays strong birefringence, with total illumination (B) alternating with total extinction (C). Note the presence of numerous bundles of Sharpey’s fibres; (D) aspect of osteocyte lacunae in a longitudinal section from the femur of C. goliath. The lacunae are oriented parallel to the bone layers, and they display short canaliculi; (E) long, branching canaliculi spreading in the femoral cortex of Trichobatrachus robustus (specimen ZFMK 83751); (F) occurrence of such long canaliculi in a thick layer of peri-medullar endosteal bone tissue (in polarized light); (G) rounded aspect of osteocyte lacunae, with long canaliculi, in a cross section of T. robustus femur; (H) spindle-like aspect of the osteocyte lacunae in a cross section from Pipa pipa humerus (specimen MNHN.AC.1954.325). Insert: closer view at the cell lacunae. Abbreviation: Sf, Sharpey’s fibres.	Figure 3. General features of bone histology in the Anura.

Vascular canals in the bones of anurans. (A)Variably oriented canals (radial, oblique, longitudinal) in the humeral cortex of Pipa pipa (individual N° 1 of specimen MNHN.AC.1954.325). The arrows point to a radial canal and a primary osteon; (B) Deflection of cortical bone layers (arrow) under vascular canals in the humeral cortex of P. pipa; (C) longitudinally oriented primary osteons, with a random spatial distribution, in the femoral cortex of Amietophrynus regularis (specimen MNHN.
