Illustrations of histological sections of E11.5 mouse embryo in the frontal plane. A) Anterior-most section illustrates fusion between the medial nasal and lateral nasal prominences. B) Posterior sections, on the other hand, show fusion as occurring between the medial nasal and maxillary prominences. The exact position of the prominences is demarcated by the nasolacrimal groove (black arrowhead). The site of bucconasal membrane formation at the site of fusion is also between the maxillary and medial nasal prominences (red arrowhead). Epithelial tissue in the nasal cavity and brain are depicted in grey. br, brain; lnp, lateral nasal prominence; mnp, medial nasal prominences; mxp, maxillary prominence; md, mandible; nc, nasal cavity; nf, nasal fin.
