Comparative study of some Histomorphological observations between the tongue of the wild rabbit breed (Lepus capensis) and local rabbit breed (Oryctolagus cuniculus)


This study was carried out on adult eight healthy local breed and eight adult wild rabbits of both sexes, to compare morphology and histology between the tongues of them. The tongue of wild rabbit observed relatively longer, wider and thinner than that of local rabbit. Both groups have tongue consist of root, body and tip. The dorsal surface of the tongue of wild rabbit is containing median groove and transverse ridges. Histologically, the tongue in both wild rabbit and local rabbit was covered by keratinized stratified squamous epithelium. The tongue of wild rabbit has thicker mucosa and sub mucosa than that of local rabbit and the longitudinal muscular layer externally and circular layer internally in contrast of local rabbit, also taste buds appear in lingual papillae in both wild rabbit and local rabbit excepted filiform papillae not contain taste buds
