摘要:
Closure between the secondary palate and the primary palate and between the former and the nasal septum was studied in the Syrian golden hamster at light- and electron-microscopic level. Sequential changes in the epithelia before, during and after the closure of the primary and the secondary palate were described. A characteristic epithelial thickening was observed prior to epithelial fusion between the nasal septum and the secondary palatal shelf. Fusion of the opposing epithelia was characterized by formation of desmosomes. An unilateral or bilateral empty space was observed on each side of the epithelial seam, and it was suggested that this may represent the incisive foramen in the adult.
