Plate 2. Pig Palate Development

Fig. 9. Cross-section of the head of the 12 mm embryo, slightly oblique, thus showing on one side, the fused processes where mesenchyme has invaded the area, on the other, the bucco-nasal membrane.

Fig. 10. Cross-section of the head of the 12 mm. embryo posterior fig. 9, showing the union of the processes on one side and the blind sac on the other.

Fig. 11. Cross-section through the head of a 17 mm. embryo showing primitive choanae.

Fig. 12. Cross~section through the anterior region of the head of a 27 mm embryo showing the shorter palatal processes.

Fig. 13. Cross-section through the head of a 27 mm. embryo posterior to fig. 12, to show the processes longer in this middle region.

Fig. 14. Cross-section of the head of the 50 mm. embryo, showing the anterior communication of the nasal and mouth cavities.

Fig. 15. Cross-section through the head of the 30 mm. embryo, posterior to fig. 14, to show the fusion of the processes, the slight indication of the invasion of mesemchyme and the fusion of the processes with the nasal septum.

Fig. 16. Cross-section through the head of the 30 mm. embryo in the posterior region to show the ventral separation.

Fig. 17. Cross-section of the 39 mm. embryo cut slightly oblique, showing on one side the respiratory duct cut off,on the other, the connexion with the respiratory cavity.
