The present investigation was carried out to study the histological features of vomer nasal organ in Indigenous Gazelle. Six adult Gazelle were used. The results indicate that, the Vomer nasal organ was symmetrical tubular organ included two parts: Conducting and olfactory parts. Olfactory part involved vomer nasal duct. The conducting part involved the incisive duct and incisive papilla which lined by stratified squamous epithelium, the incisive duct measured (623.8±12.1µm) in diameter and lined by ciliated pseudo stratified columnar epithelium. The vomer nasal duct has significant widest diameter (1040±50.9µm) and oval- circular lumen with two walls; medial wall was lined with neuro-epithelium which has significant epithelial height (83.0±2.4µm), lateral wall has lined with respiratory epithelium of height (43.4±3.6µm). The lamina propria- submucosa beneath medial wall was loose connective tissue contained many of wide veins and axons. The lamina propria- submucosa beneath incisive duct and lateral wall possessed compound tubuloalveolar mucous glands.
