Makale Kodu (Article Code): KVFD-2009-917 SummaryIn 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.

There are many preservation techniques that are used to ensure that the changes (odor, color, and elasticity) in the characteristics of the animal or human bodies after death are minimized in the field of anatomy. One of the most modern anatomic specimen preparation methods is the plastination technique. Therefore, primary plastination stages were applied to the muscle tissue in this study. The aim of the current study is to present color changes in muscle tissue quantitatively by using a colorimeter device in every stage of the standard silicone plastination technique until the last product is obtained. Color analyses were performed on the muscle tissue after each stage of the plastination. Throughout the whole process, it was observed that the stage when the value of color change from green to red in the product was the closest to the fresh tissue was the 1 st acetone bath. The value of color change from blue to yellow was closest to the fresh tissue at the gas curing and hardening stage. Furthermore, the closest values to the fresh tissue were recorded after the impregnation stage when the variations in plastinates were evaluated in terms of brightness. Color changes in plastinates, which have been described as close to the natural color up to today, were determined through statistical data in this study. Moreover, as a result of this dissertation, it was asserted that colorimeter can be effectively used in the field of anatomy due to the advantages it holds.

Bu araştırmada üç farklı kanatlı türüne ait olan horoz, erkek ördek ve güvercinde aorta descendens'in seyri ve dagılımı karşılaştırmalı olarak incelendi. Çalışmada Ankara yöresinden temin edilen ve erişkin olmak üzere iO adet Leghom ırkı horoz, 10 adet yerli ördek ve LO adet yabani güvercin kullanıldı. Materyaller damar içi latex enjeksiyonu ve korozyon kast yöntemleri ile doldurularak diseksiyonları yapıldı. Araştırmada üç farklı türe ait horoz, erkek ördek ve güvercinde aorta descendens'in seyri ve vermiş oldugu dallar ortaya kondu.

A number of iO Leghom roosters, 10 domestic drakes, and LO pigeons, all being mature and provided from Ankara region, were used in the study. The materials were either injected with red-colored latex through the left ventricule or corrosion casted wİth mono-and polymethylmethacrylate (takilon). Pattem of branching and distribution of the descending aorta in rooster, drake and pigeon, each of which belongs to three different avi an orders were documented comparatively.
