Abstract

This study was carried out to investigate the anatomical and histological structure of larynx, trachea and syrinx in male and female chickens of Aseel breed. Healthy adult chickens of Aseel breed, including 4 female and 4 males were used in this study. By dissecting the neck and chest cavity of the birds, topographical characteristics of larynx, trachea and syrinx were recorded. The dissected tissues were microscopically examined by staining with hematoxylin and eosin by using routine histological procedures. In this breed, larynx was composed of cricoid cartilage, procricoide cartilage and a pair of arytenoid cartilage while thrachea contained 111-118 cartilage rings. Surfaces of transversal sections of cartilage rings changed along the trachea. A series of papillae caudally directed and sequentially located along the lateral borders of glottis were observed. At the back side of laryngeal sulcus, two series of transversally located papills with backward directed free ends were detected. Syrinx was observed in the tracheobronchial type. Tympanum was observed to be composed of four cartilage rings. By microscopic examination of larynx mucosa was observed to be covered by multilayer keratinized epithelial tissue. The mucous glands and hyaline cartilages were present in the lamina propria. Tunica mucosa of syrinx was covered by pseudo multilayer ciliar epithelial cells. The pessulus was composed of hyaline cartilage. The results indicated that although differences in trachea lentgh and diameters of cartilage rings existed between sexes, larynx, trachea and syrinx in Aseel breed were highly similar to those in other chicken breeds

Özet

Bu çalışma Aseel ırkı horoz ve tavuklarda solunum yollarını şekillendiren larynx, trachea ve syrinx'in anatomik ve histolojik yapısını incelemek amacıyla yapıldı. Çalışmada erişkin, sağlıklı 4 dişi ve 4 erkek Aseel ırkı horoz ve tavuk kullanıldı. Kuşların boyun ve göğüs boşluğu diseke edilerek larynx, trachea ve syrinx'in topografik özellikleri kaydedildi. Total olarak diseke edilen dokular rutin histolojik işlemleri takiben Hematoksilen&Eozin ile boyandı. Çalışma neticesinde larynx'in cartilago cricoidea, cartilago procricoidea ve çift olan cartilago arytenoidea'dan meydana geldiği tespit edildi. Trachea'nın 111-118 kıkırdak halkasından oluştuğu belirlendi. Kıkırdak halkalarının transversal kesit yüzünün trachea'nın seyri boyunca farklılık gösterdiği saptandı. Glottis'in lateral sınırları boyunca, tek sıra halinde ve art arda dizilen caudal yönlü papilla dizisi gözlendi. Sulcus laryngeus'un gerisinde serbest uçları geriye dönük papillaların oluşturduğu transversal seyirli iki sıra papilla dizisi tespit edildi. Syrinx'in tracheobronchial tipte olduğu gözlendi. Tympanum'un dört adet kıkırdak halkasından oluştuğu belirlendi. Mikroskobik incelemede larynx mukozasının keratinize, çok katlı yassı epitel ile örtülü olduğu görüldü. Lamina propria'da müköz bezler ve hyalinli kıkırdak bulunmaktaydı. Syrinx'in tunica mukozası siliyalı, yalancı çok katlı epitel ile kaplıydı. Pessulus hiyalinli kıkırdaktan oluşmaktaydı. Sonuç olarak; Aseel ırkı horoz ve tavuklarda, trachea uzunluğu ve halkaların çapları açısından cinsiyetler arasında farklılıklar bulunmasına rağmen genel olarak diğer evcil kanatlılarla benzerlik gösterdiği kanaatine varılmıştır
