The purpose of this study was to determinate The location, arrangement , the total number of fungiform papillae and number of those papillae in different regions of Twenty Tongues of Iraqi sheep (males) in different ages(two, four month embryo ,five month old and two year old) .Histological sections of fungiform papillae in different region from tongues were studied. Bapillae diameters and number of taste buds was assigned for each sample. The results showed that the papillae arise during embryological stage was thickened epithelium forming protrusion on the tongue surface. No significant differences was observed in the total number of the fungiform papillae in all ages. All papillae were distributed in the rostral part of the tongue, The papillae diameter showed significant increase respect to ages in all region. The taste buds were showed significant difference in number between 4 month embryo and 5 month old, while no significant between 5 month old and 2 year old. The number of taste buds for each papillae was more in cranial and caudal part compared with the middle part. The diameter of taste buds showed difference according to ages in all regions.
