Abstract: This study was carried out to investigate the morphological development of the tongue in the foetal stage of camelus dromedaries by light microscopy. In foetuses of about 60 days, the tongue tissues showed thickening of the epithelium into about 4-6 layers of cells. In foetuses of about 75 days, mesenchymal tissue was observed under the epithelium. Rudiments of some papillae were observed at this time. Collagenous fibre and blood vessels were scant in the lamina propria. In the 90 days old foetuses, their was further differentiation of the epithelium rudiments into some papillae and this continued to mature until in foetuses of about 105 days, were early rudiments of taste buds were observed and in 120 days old foetuses taste buds were developed well and taste buds cell were recognizable.
