Ten pairs of quails and <br>chickens were included in this study as one of them is flying and the other one is flightless bird species. The tissues cut into serial <br>sections of 5 µm thickness were selected according to systematic random sampling and stained with cresyl violet. Volume and volume <br>fractions were calculated in accordance with the Cavalieri principle. Student’s t-test was used to evaluate volume fraction differences <br>among the species. The volume fractions of grey matter in cervical enlargement of chicken and quail were 0.277 ± 0.005 and 0.346 ± <br>0.014 (Mean ± Standart Deviation), respectively (p < 0.001). There was a significant difference between chicken and quail cervical <br>enlargements in terms of volume fraction values of grey matter. On the other hand, the Cavalieri principle was considered as an <br>unbiased, accurate and effective method for volume and volume fraction estimations. </span>   <br style="font-variant-numeric: normal; font-variant-east-asian: normal; line-height: normal; text-align: -webkit-auto; text-size-adjust: auto;">}, number={1}, publisher={Ankara University}
