Abstract :
Inroduction & Objective:The smallest bones in the body is located in the middle ear. It transmits air from the outer ear to the inner ear and this ossicle important in physiology and pathology . There is no study performed on the histology of middle ear bones in the buffalo. Material and Method: For this study, eight male and female buffalos heads were selected from the slaughterhouse. Then histological section was taken from the middle ear ossicles and histologically stained by haematoxylin-eosin staining. At the end the middle ear ossicles were studied histology and the internal structure of the ossicels and joints between them was studied. Results: The histological results showed middle ear ossicles in buffalo was Compact bone and It has synovial joints.The joint between malleus bone and incus bone and The joint between incus bone and stapes bone had diarthrosis joint and a articular capsule covered the outside of the articular space. This articular capsule was thicker in the joint between the malleus bone and incus bone than the incus bone and stapes bone. Around the foot plate of the staped bone obseves annular ligament that connected the joints of the stapes bone to the ventral window. Conclusion: The results of the present study can provide basic information for other researchers to physiology and pathology in this regard.
