| Thepresentstudywasconductedontwelve ostrich heads of both sexes, aging from1.5-2years.Thespecimenswerecollected from the abattoirs of ostrich in Ismaelia Province-Egypt, immediately after slaughtering. Tenspecimenswere fixed in10%formalin, 1%glycrine and 1%thymol, and dissectedfordetaileddescriptionof thehyobranchial apparatus and thecraniallarynx.[Forthefinedissection,amagnifyingglassx8wasused. Two heads were fixed in neutral buffered formalin for the light micro-scopic observation of the larynx. The laryngeal specimens were subje-cted to the ordinary histological technique. 5-7 um thick serial sections were obtained and stained with different stains.The present study reve-aled that, the skeleton of the hyobranchial apparatus of ostrich was formed from, dagger like basibranchial cartilage with a clear flexible cornue of paraglossal process, ceratobranchial bone and epibranchial cartilage. The skeleton of the cranial larynx was formed from four cartilages; single cricoid, single procricoid and paired arytenoids. | ||
