“…Diverticulum humerale aerated humerus in Gallus domesticus [11], Denizli rooster [21], White Pekin duck [15] and fowls [8], but not in the quails of this study. Therefore, this study indicated that humerus in the quail is a non-aerated bone.…”

ABSTRACT. This study was conducted to reveal the morphological characteristics of the lung and air sacs in Coturnix coturnix japonica (Japanese quails). Ten quails were allocated into two groups. Tracheas of 5 quails with neoprene latex and 5 quails with methylmetacrylate were injected to fill the trachea and air sacs. Latex embalmed animals were stored in 10% formaldehyde solution for two months. Animals given methylmetacrylate were maserated in 30% potassium hydroxide at 40°C for two days. Lungs were located in the dorsal part of the thorax and very close to the thoracic vertebrae and ribs. Shorter than the dorsal border, the ventral border lied between the 3rd and 6th ribs. Cervical, clavicular, cranial thoracic, caudal thoracic and abdominal sacs were identified. These sacs had connection with the 3rd, 4th and 5th lateroventral and 4th mediolateral bronchi. Saccus cervicalis was located on the left and right portions of the vertebrae cervicales et thoraricae with a pronounced communication ventromedially. However, the cervical sac aeration of only all cervical vertebrae was present in this study. Humerus was a non-aerated bone. Pneumatic foramen was absent and did not aerate the sternum. Cranial thoracic sac connected to the 1st, 2nd and 4th medioventral bronchi and gave no diverticulum for aeration. Cranial thoracic sac received air through the 4th medioventral and the 1st and 2nd lateroventral bronchi. Left and right abdominal air sacs paramedially produced diverticulum femorale, but this diverticulum did not enter the femur.

“…By contrast, a number of studies report that tracheal and bronchial cartilages in some birds are ossified. For example, ossified areas are encountered in the posterior surfaces of the tracheal cartilages in the common murre (Miller et al, ), complete ossification is reported in elderly chickens (Gross, ; Hodges, ) and Peking duck (Mannega and Calhoun, ), partial ossification is shown on the ventral sides of the last two tracheal cartilages in turkeys (Cover, ). The tympanum, tracheal and bronchial cartilages are ossified in the common murre (Miller et al, ).…”

The phonation process of vertebrates is influenced by the material characteristics of the participating structures, ranging from molecular to macroscopic dimensions. Good animal models for phonation research are still lacking. Due to easy availability and relatively simple structure, the syrinx of birds might serve as a good animal model for this purpose. Our aim was therefore to determine structural features of the syrinx and obtain insights into its mucus layer characteristics. Epithelium and glands were analyzed using histological, histochemical, and immunohistochemical methods and conclusions were drawn on the use of the syrinx as a model for phonation research by comparing the epithelium and its mucus characteristics to human laryngeal secretions. Ten adult partridges were analyzed. The tympanum of the syrinx developed from the last two tracheal cartilages, whereas the caudal part of the syrinx was formed from eight pieces of bronchial cartilages. The tracheal and bronchial epithelia and the pessulus of the syrinx were lined by pseudostratified columnar epithelium in which goblet cells and intraepithelial glands were localized. Collagen fibers were distributed in the lamina propria of all parts of the syringeal mucosa. Elastic fibers in the membranes of the syrinx showed evident distribution. All glandular epithelial cells and goblet cells were positive for neutral, acidic and carboxylated mucins were dominant in particular. Epithelium and glands revealed positive reactivity with antibodies to the mucins MUC1, MUC2, and MUC5AC. Of these, MUC2 and MUC5AC were dominant. The syrinx of partridge can serve as a good ex vivo model for phonation research. Anat Rec, 298:602-617, 2015. V C 2014 Wiley Periodicals, Inc.

“…Whereas the paired caudal thoracic sacs lie more caudally between the body wall and the abdominal sacs (4). The abdominal sacs have perirenal diverticula which extend between the kidney and pelvis, and femoral diverticula which surround the head of the femur and penetrate between the thigh muscles (15) Morphology of the air sacs in several avian species has been well documented (11,14,17,19) however, studies on that in mallard ducks, found wide-spread all over the world, are very scarce (1,13). This observation aimed to investigate the features of the air sacs, and document the differences if there is, and further expanding our knowledge with contribution to the literature.…”

Summary:This study aimed to observe the air sacs (Sacci pneumatici) in mature Mallard ducks (Anas platyrhynchos). After animals (n=9) were euthanased by combination of ketamine 60 mg/kg and xylazine 6 mg/kg, methylmethacrylate (Takilon) was injected by way of trachea. They were put in a cold-aired room for two months for polymerization. Then, they were maserated with 3% potassium hydroxide at 40 °C, cleaned with tap water, coloured by glass dye and photographed. Morphology of the cervical and clavicular air sacs was consistent with previous studies. The cranial thoracic air sacs were smaller than the caudal sacs pneumatising the second to seventh ribs by their diverticula. The caudal thoracic air sac had no diverticulum. The left abdominal air sac had two portions, i.e. the cranial and caudal sacs; the latter aerating the last three ribs and synsacrum, the former being smaller and narrower. Moreover, the right abdominal air sac was bigger than the left sac.Key words: Air sac, mallard duck. Yeşil başlı ördekte (Anas platyrhynchos) hava keseleri (Sacci pneumatici)Özet: Bu çalışma yeşil başlı ördekte (Anas platyrhynchos) hava keselerini (Sacci pneumatici) göstermeyi amaçladı. Hayvanlara (n=9) 60 mg/kg ketamin ve 6 mg/kg ksilazin bileşimi ile ötenazi uygulandıktan sonra, trakea yoluyla metilmetakrilat (Takilon) şırıngayla verildi. Polimerizasyon için soğuk hava odasında iki ay bekletildi. Takiben 40 ºC'de %3'lük potasyum hidroksitle masere edilerek akar su altında temizlendi, cam boyası ile her bir hava kesesi ayrı renklerle boyandı ve fotoğrafı çekildi. Servikal ve klavikular hava keselerinin morfolojisi önceki çalışmalarla uyum gösterdi. Divertikulum tarafından 2-7. kaburgaları havalandıran kranial torasik hava kesesi kaudal keselerden daha küçüktü. Kaudal torasik hava keselerinde divertikulum görülmedi. Sol abdominal hava kesesi kranial ve kaudal olmak üzere iki parçalıydı. Kaudal kısım son üç kaburga ve synsacrum'u havalandırdığı ve kranial keseden daha büyük ve geniş olduğu kayıt edildi. Ayrıca, sağ abdominal hava kesesi soldan daha büyük olduğu görüldü. Anahtar sözcükler: Hava kesesi, yeşil başlı ördek.
