The gross anatomy of larynx, trachae and syrinx in goose (Anser anser domesticus)

Bu çalışmada 4000-5000 g ağırlığında 8 adet evcil olgun kaz (Anser anser domesticus)’a ait larynx, trachea ve syrinx incelendi. Larynx’in tek olan cartilago (cart.) cricoidea, cart. procricoidea ve çift olan cart. arytenoidea’dan oluştuğu belirlendi. Seyri boyunca çaplarında değişiklik görünen trachea halkalarının sayısı 137-140 arasındaydı. Trachea’nın orta bölgesinde yer alan halkalar bir önceki ya da sonraki halka ile temas ederek ‘’H’’ harfine benzer bir şekil almaktaydı. Bazı halkalar dorsal’de bazıları ise ventral’de iki’ye çatallanmaktaydı. Cartilagines tracheosyringeales ve cartt. bronchosyringeales’den meydana gelen syrinx’in tracheobronchial tip olduğu belirlendi. Tracheosyringeal kıkırdaklar birbirleriyle kaynaşmış tüp şeklindeydi. İlk ikisi hariç halkaların tamamı kemikleşmişti. Cartilagines bronchosyringeales altı adet ‘C’ şeklindeki kıkırdak halkalardan meydana gelmişti. Son dört cartt. bronchosyringeales’in açık olan median yüzlerinin birbirlerine, içerisinde düz kas hücreleri bulunduran bir bağ doku ile sıkıca bağlanmaktaydı. Membrana tympaniformis lateralis ve membrana tympaniformis medialis’in varlığı gözlendi. Membrana tympaniformis lateralis tympanum ve birinci cart. bronchosyringealis arasında, membrana tympaniformis medialis ise pessulus ve ikinci cart. bronchosyringealis arasındaydı. Sonuç olarak, trachea’nın orta bölgesinde yer alan kıkırdakların ‘’H’’ harfine benzer çatallanması ve aynı zamanda tympanum’un tamamen kaynaşıp kemikleşmesi kaz için karakteristikti.

Kazda (Anser anser domesticus) larynx, trachae and syrinx’in makroskobik anatomisi

In this study, larynx, trachea and syrinx of eight domestic mature geese (Anser anser domesticus) weighing 4500-5000g were examined. The larynx was formed by single cartilago (cart.) cricoidea and cart. procricoidea, and a paired cart. arytenoidea. Cartilagines trachea numbered 137-140 and variations in their diameters were detected along their courses. The cartilage rings localized near the middle of the trachea were in contact with the previous or following rings and formed “H” letter shape. Some rings were dorsally and some were ventrally forked. The syrinx was tracheobronchial type and formed by cartilagines (cartt.) tracheosyringeales and cartt. bronchosyringeales. Cartilagines tracheosyringeales were tube shaped and fused in both directions. Rings were completely ossified except the first two. Cartilagines bronchosyringeales were made up of six ‘C’ shaped cartilage rings. The open medial faces of the last four cartt. bronchosyringeales came closer to each other and facing left and right parts were tightly attached to each other by connective tissue smooth muscle. The membrane tympaniformes lateralis and medialis were observed. The membrane tympaniformes lateralis was between the tympanum and the first cart. bronchosyringealis, and the membrane tympaniformes medialis was between the pessulus and the second cart. bronchosyringealis. In conclusion, the cartilage rings in middle parts of trachea which seem to be “H”-shaped forked and also the tympanum which is completely fused and ossified characteristic for the goose.
