Review Anatomical Features Ossicular Cattle and Pigs, with Special Reference to Morfometric Characteristics Bule Tympani

There are relatively few studies especially in our region, who have studied the ossicles in domestic animals. In the existing literature, textbooks, morphology, anatomy and zoology, anatomy atlases and technical papers there are a variety of information about the existence of certain ossicles. The literature states that there are three auditory ossicles: Maleus, Incus and Stapes. The fourth auditory ossicles - Os lenticulare, often lacking in the papers and books of the respective authors. At our university, we have established a laboratory for anatomical research, and the first task was to on a number of samples determines the existence or absence of lenticular axis in cattle and pigs. For this purpose we have to slaughter line separated by 30 processed head of cattle and pigs, which we later processed in our laboratory. Native examination and after cooking isolated temporal bone and isolating the ossicles, clearly we have established the existence of four auditory ossicles - Os lenticular. We have performed a morphometric analysis Bule tympani, measure the length and width of pigs and cattle, statistically processed and presented.
