Fig. 5

The naso-palatal complex in the brown anole at stages 8 based on the transverse histological sections (A, G) and 3D reconstructions (BF′ and H). A Section just posterior to the vestibulum. B Ventrolateral view of the palate. B′ Ventrolateral view of palate (semi-transparent). C Anterolateral view of the snout. D Lateral view of the left nasal cavity. E Sagittal cutaway of the semi-transparent snout showing the medial view of the left nasal cavity. F, F′ Nasal cavity rendered with partial opacity: medial (F) and anterior (F′) views. G Section at the level of the early VNO. H Dorsal view of the left nasal cavity. Abbreviations: a anterior, aos antorbital space, e eye, ecs extraconchal space, el lower eyelid, en external naris, ev early VNO, fnm frontonasal mass, lnc lateral nasal concha, lnp lateral nasal prominence, m medial, mxf maxillary fold, mxp maxillary prominence, np nasal plug, oe sensory olfactory epithelium, pct primitive choanal tube, poch primitive outer choana, Stt Stammteil, ves vestibulum. Red star primordium of the vomerine cushion, yellow star primordium of the anterior segment of the palate, white star choanal diverticulum, red arrowhead nasolacrimal groove, red arrows groove between the lower eyelid and the maxillary prominence, two white arrows fusion between the maxillary and lateral nasal prominence with the frontonasal mass, dashed ellipse entrance of the early VNO to the primitive choanal tube. Note: italicized label on 3D image (lnc) indicates the concavity in the nasal cavity. Scale bars 200 μm (3D) and 100 μm (histological sections)
