Abstract

The Middle Ear of Ruminants: An Anatomical and Bio-Metrical Comparison between the Lori Sheep and the Native Cow in Shahrekord District

Rahmat Allah Fatahian Dehkordi

The ossicles consist of three small bones known as the smallest bones in the body that play an important role in transmitting sound to the inner ear. In order to study the details of middle ear ossicles in Lori sheep and native cattle, bio-anatomical parameters of malleus, incus and stapes ossicles were measured. The age factor is not considered and all animals were adult. Investigations showed that there was no significant difference in the levels of the middle ear bone between the two sexes. In this study, the ossicles were carefully described by the appropriate devices and after separation, the ossicles were measured using caliper and digital scales. Bio-anatomical changes were evaluated under stereomicroscope magnification. The results showed that all three bones structure is similar to other animals. Biometric aspects indicated that most of the changes belonged to malleus and incus bone. After examining the two species under study, the least significant change was observed between the two animals in the stapes. In conclusion, this study was able to compare middle ear ossicles between sheep and native cattle in Shahrekord district. Anyway, it is conceivable that the biometric sizes of the middle ear bones may be affected by animal species.
