The VNO at the late developmental phase of the naso-palatal complex of the brown anole based on the transverse histological sections (A–B, C and C”) and 3D reconstructions (B′, C′ and D–F). A Section through the VNO at stage 12. A’ Section through the vomeronasal sensory epithelium at stage 12. B Section through the right VNO at stage 17. B′ Cartilage of the mushroom body at stage 17. C Section through the VNO at stage 18. C′ Cartilage of the mushroom body at stage 18. C” Higher magnification of the apical part of the vomeronasal sensory epithelium, stage 18. D–F Anterolateral views of the VNO at stages: 12 (D), 17 (E) and 18 (F). Abbreviations: cmb cartilage of the mushroom body, dv duct of the VNO, L1–L3 layers of the vomeronasal sensory epithelium, ld lacrimal duct, lta lamina transversalis anterior, mb mushroom body, mx maxilla, ns nasal septum, smx septomaxilla, ves vestibulum, vom vomer. White arrows pigment granules, red asterisk ventral channel of the VNO, I and II parts of the VNO duct. Note: italicized label (mb) on 3D images indicates the concavities in VNOs. Violet in B′ and C′ is a cartilage and the remaining colours of 3D structures as in Fig. 9. Scale bars 50 μm (A, B, C), 20 μm (A’ and C”) and 250 μm (D–F)
