Fig. 8

Origin and early differentiation of the lacrimal duct in the brown anole based on 3D reconstructions (A, A’ and C) and transverse histological sections (B, D and E). Stage 8: ventrolateral view of the snout (A), semi-transparent snout in the same view (A’) and section at the level of the primordial lacrimal duct (B). Stage 9: ventral view of the semi-transparent palate (C) and section at the level of the lacrimal duct “between” the lacrimal canaliculi (D). Stage 9/10: section at the level of the lacrimal canaliculi (E). Abbreviations: alc anterior lacrimal canaliculi, e eye, el lower eyelid, fnm frontonasal mass, ld lacrimal duct, lnp lateral nasal prominence, mxp maxillary prominence, plc posterior canaliculi, pld primordial lacrimal duct. Red arrowhead nasolacrimal groove, two long red arrows groove between the lower eyelid and the maxillary prominence, single short red arrow freed anterior end of the lacrimal duct. Scale bars 200 μm (3D) and 50 μm (histological sections)
