A Morphological and Stereological Study on Cervical Segment of Spinal Cord of Quails.

ABSTRACT

In this study, volume densities of white and grey matters of cervical segments of spinal cords of quail were investigated stereologically. In both sexes, mature, six quails were used as material of this study. All animals were fixed by perfusing in 10% buffered formalin. Tissue specimens were obtained from cervical spinal cords. These tissue specimens were cut every fiftieth section at 5 µm thickness by a microtome. And mean six or seven sections were examined from every block by this method at microscope. After that, these sections were stained by haematoxylin eosin and photographed. Densities of volumes of all tissues of cervical segments of whole spinal cords and white and grey matters were calculated with principle of Cavalieri. As a result, total volume of spinal cord, volumes of white and grey matters of cervical segment and volume rates of white and grey matters were calculated.
