Morphohistological study of the Esophagus of the one Humped Camel (Camelus Dromedaries)

The esophagus of one-humped camel was studied grossly and histologically. Different stains were used to examine the glands and musculature. The esophagus of camel appeared to be similar to that of other ruminants in absence of the abdominal portion. Specific modifications were observed in camel s esophagus different than the esophagus of other domestic animals in presence of a well developed pharyngoesophageal limen (fold), keratinization of the stratified squamous epithelium and irregularities of the tunica muscularis. These changes were proposed to be factors in facilitating swallowing and regurgitation of rough food. Arterial blood supply was found to be similar to ox and small ruminants.
