Otophysine fishes are characterized by Weberian ossicles connecting the swimbladder to the ear acoustically. In order to determine the degree to which these ossicles contribute to auditory sensitivity, the tripus was unilaterally or bilaterally extirpated in goldfish and hearing thresholds determined. The auditory evoked potential (AEP) recording technique was used to measure auditory sensitivi...

the aim of this study was to determine the anatomical features of the auditory ossicles in rat. twenty temporal bones from 10 adult rats were used. the features of the ossicles were assessed with an ocular micrometer and photographed by a stereomicroscope. finally, all data were evaluated and analysed using the sigma statt software. temporal bone in rat was similar to other animals consists of ...

Hearing loss and individualities Studies have shed light on the physiology of auditory system, which is fundamental to understanding diversity found in deaf community. A study by Silva discusses 3 types load described Silman & Silverman’s classification system: conductive, neurosensory, mixed. The first type caused inflammatory processes, excess cerumen external canal, changes articulation ossi...

The presence of three interconnected auditory ossicles in the middle ear is a defining characteristic of mammals, and aspects of ossicle morphology are related to hearing sensitivity. However, analysis and comparison of ossicles are complicated by their minute size and complex three-dimensional shapes. Here we introduce a geometric morphometric measurement protocol for 3D shape analysis based o...
