“…In this study, the dimensions of the thyroid gland in long-legged buzzard were determined as smaller than the dimensions for chicken (4,8), duck, goose, pigeon (8) and buzzard (16). Furthermore, the numbers of the long-legged buzzard at both sides were The parathyroid gland, which secrets parathormone to regulate calcium and phosphate metabolism, had seen to have similar shape and dimensions to the concerned by literature (3,8,10,17). In literature (1, 10) it was reported that the parathyroid gland of the domestic birds consists of cranial and caudal gland touching each other and the right cranial parathyroid gland is in contact with thyroid gland where this connection do not exist at the left cranial parathyroid gland.…”

“…Takagi and Yamada (17) indicated that this gland develops significantly smaller in grass parakeet compared to the other birds and they attributed this to the proportion regarding its small body weight. The measurements from the long-legged buzzards obtained in this study support this argument.…”

“…Right ultimobranchial gland was located at the intersection of the oesophagotrachebronchial vein and oesophagotrachebronchial artery in seven materials, but in one material it was located at the caudal of the oesophagotrochebronchial vein and at the ventromedial of the vagal nerve. Takagi and Yamada (17) reported that in parallel to the reptiles, in the grass parakeet the left gland was more developed than the right gland. In this study, a significant size difference was not observed between the glands on both sides.…”

“…There are previous studies on the morphologic structure and the topographic anatomy of the carotid body, thyroid gland, parathyroid gland and ultimobranchial gland of various avian species (4,9,13,16,17). The purpose of this study is to identify the localization of the thyroid gland, parathyroid gland and ultimobranchial gland spesific to reptile and avian species and in long-legged buzzards and to contribute to the anatomy literature.…”

“…Ultimobranchial gland which includes calcitonin-secreting C cells, is a gland specific to amoeba, reptile and birds and it is generally located at the in the caudal side parathyroid gland (3,8,14,15). The borders of the gland were irregular shape due to lack of the surrounding capsule (17).…”

Summary:The objective of this study to determine localization of ultimobranchial gland, specific for reptiles and bird, thyroid and parathyroid glands in long-legged buzzard. A total of eight adult long-legged buzzard, brought to clinics of faculty and could not be rescued with medical treatment, were used for the study. Thyroid gland was among the two branches of the furcula at the entrance of the thoracic inlet. The length, width and thickness of thyroid gland which was the largest of the inspected glands were 4.5±0.8 mm, 2.87±0.53 mm and 2.74±0.42 mm, respectively. Parathyroid gland, the second largest gland, was seen as the a number on the right side, while it generally had two numbers (cranial and caudal) on the left side. While the length, width and thickness of the cranial parathyroid were 1.73±0.38 mm, 1.13±0.18 mm and 1.05±0.67 mm, respectively, the same measurents for the caudal parathyroid were 1.13±0.23 mm, 0.94±0.21 mm and 0.59±0.16 mm respectively. Ultimobranchial gland was found to be asymmetric on both sides (right and left) and being very small. Ultimobranchial gland on the left side generally placed caudal of the caudal parathyroid gland and was determined at the level where begining of common carotid artery in inspected materials. Ultimobranchial gland on the right side was generally located at between oesophagotracheobronchial vein and oesophagotracheobronchial artery. The gland was oval shaped and its average length 1.7±0.47 mm, width 0.94±0.35 mm and thickness 0.5±0.14 mm were determined. In conclusion, the localization of the inspected glands in long legged buzzard was similar to that of the other birds although differences observed in the numbers of parathyroid gland and sizes of the other all glands.Key words: Anatomy, parathyroid gland, thyroid gland, ultimobranchial gland, long-legged buzzard.Kızıl şahinde (Buteo rufinus) glandula ultimobranchialis, glandula thyroidea ve glandula parathyroidea'nın lokalizasyonu Özet: Bu çalışma, sürüngen ve kanatlılara özgü olan glandula ultimobranchialis ile glandula thyroidea ve glandula parathyroidea'nın kızıl şahindeki konumlarının belirlenmesi amacıyla yapıldı. Çalışmanın materyalini fakültemiz kliniklerine getirilen ve kurtarılamayan sekiz adet ergin kızıl şahin (Buteo rufinus) oluşturdu. Glandula thyroidea'nın kızıl şahinde göğüs boşluğu girişinde furcula'nın iki kolu arasında yer aldığı görüldü. İncelenen bezler içerisinde en büyük olan glandula thyroidea'nın uzunluğu 4,5±0,8 mm, eni 2,87±0,53 mm ve kalınlığı ise 2,74±0,42 mm olarak saptandı. Büyüklük bakımından ikinci sırada olan glandula parathyroidea'nın sağda bir adet, solda ise genelde cranial ve caudal olmak üzere iki adet olduğu görüldü. Cranial'de yer alan glandula parathyroidea'nın uzunluğu 1,73±0,38 mm, eni 1,13±0,18 mm ve kalınlığı 1,05±0,67 mm iken caudal glandula parathyroidea'nın uzunluğu 1,13±0,23 mm, eni 0,94±0,21 mm, kalınlığı 0,59±0,16 mm olarak ölçüldü. Glandula ultimobranchialis'in sağlı sollu asimetrik olarak bulunduğu ve oldukça küçük şekillendiği görüldü. İncelenen matery...

Morphological investigation of the ultimobranchial body (Ult) of the Urodeles amphibian red-bellied Japanese newt (Cynops pyrrhogaster) revealed that it had only one Ult located on the left behind the arch of the aorta between the paired thyroid glands and parathyroid glands to the left of the trachia. The Ult had no capsule and consisted of a group of follicles. The follicles were made up of the cubic epithetical cells. The average size of the Ult The follicular cells of the Ult were differentiated by lead-hematoxylin staining. They also reacted positively in the immunohistochemical method using antiserum against pig calcitonin. This was a clear indication that these cells were related to the secretion of calcitonin.

Summary: A morphological and immunohistochemical study of the ultimobranchial body of reptiles Japanese lizard and snake was carried out. The ultimobranchial body of the Japanese lizard was located adjacent to the left arch of the aorta between the trachea and esophagus. It was found as a cluster or group of cells with no capsule. Grimelius' silver impregnation and lead-hematoxylin staining produced positive reactions in some of the clustered cells and follicular cells. The same reaction pattern was observed with anti-calcitonin using the PAP method. The PAP reactions were positive to antiserum against pig calcitonin, but negative to antiserum against synthesized human calcitonin. Furthermore. the PAP reactions were negative to antiserum against tyrosine hydroxylase. The immunofluorescent study of the snake ultimobranchial body revealed that most of the clustered cells and some of the follicular cells were calcitoninimmunoreactive but none was tyrosine hydroxylase-immunoreactive.Certain histological similarities exist between the Japanese lizard ultimobranchial body and snake ultimobranchial body, but the distribution of calcitonin-positive cells were slightly different. In the Japanese lizard, the positive cells were scattered between the folicles and the number was small. However, most of the cells which formed the cluster in the ultimobranchial body of snake were positive. The findings suggest that the configuration of amino acid in the Japanese lizard calcitonin and snake calcitonin are similar to that of pig calcitonin, and the reptile and the birds is a boundary of the tyrosine hydroxylase existence.Reports on the ultimobranchial body (Ult) of reptiles are numerous:
