Abstract
Yapılan çalışmada farklı kanatlı türlerine (baykuş, bıldırcın, devekuşu ve Pekin ördeği) ait pekten okuli örneklerinin ışık mikroskobik olarak incelenmesi amaçlanmıştır. Bu amaçla alınan doku örnekleri formolde tespit edilerek parafinde bloklanmış, rutin histolojik işlemlerden sonra Masson’s trikrom tekniği ile boyanmış ve incelenmiştir. Yapılan incelemeler sonucu tüm kanatlı türlerinde pekten okuliyi oluşturan temel yapı aynı olsa da pektende pili sayılarının, kan damarları çapı ve yerleşiminin, melanosit miktar ve yerleşiminin farklılıklar gösterdiği tespit edilmiştir. Bu verilere göre en fazla pili sayısına sahip devekuşlarının aynı zamanda en geniş damar çapına sahip olduğu belirlenmiştir. Bununla birlikte pili sayısı en az olan baykuşların daha küçük çaplı damarlara sahip olduğu gözlemlenmiştir. Tüm bu veriler pekten okulinin hayvan türüne göre yapısal farklılıklarının olduğunu göstermektedir. Bu yapısal farklılıkların hayvanların büyüklükleri, avlanma ve beslenme çeşitlilikleri ile ilgili olduğu, bu konu ile ilgili daha kapsamlı çalışmalar yapılması gerektiği düşünülmektedir.
