Abstract

This work aimed to throw more lights on beginning time of the first appear- ance and origin as well developmental vicissitudes of rabbit's nostril. This work was carried out on 116 rabbit embryos and fetuses of both sexes. The specimens were obtained, from 14 normal and apparently healthy adult female rabbit. At days (D) 11 there was a cleared invagination on the thickened epithelium of the nasal placode as a nasal pit. The latter had an oval in outline at 12 D and it formed the nasal sac. At 13 D the nasal sac had given rise to the primitive nasal cavity. Its external opening will differentiate to form the primitive nostril, occluded by nasal plug. At 14 D the lining epithelium of the lateral nasal wall was of variable thickness of stratified cuboidal type of epithelium. At 16 D there were a clear some cellular apoptosis in center of nasal plug. At 18-20 D the center of the nasal plug was dissoluted and the nostril was begun to canalize. At 22 D the nostril was lined by keratinized stratified squamous epithelium especially at the rostral part of nasal vestibule and the nasal vestibule was lined by thick keratinized stratified squamous epithelium. At 30 D the nostrils appeared as oblique slit like opening similar to that of newly born rabbit.
