    Investigation of Metapodium and Acropodium Bones in Siirt-Colored Mohair Goat (Capra hircus) by 3D Modeling
    (2023) İşbilir, Fatma; Güzel, Barış Can
    Studies on Artiodactyla species benefit from the use of metapodial bones. Being one of the bones that completed its development early and being well preserved because it is not affected by environmental conditions, it can be unearthed as a single piece in archaeological excavations. In recent years, the disadvantages of 2D images have contributed to developing 3D modeling methods in medicine. Adult (1-3 years old), 10 male and 10 female Siirt-colored Mohair goat metacarpus and forelimb digit bones (phalanx proximalis, phalanx media and phalanx distalis) were used in our study. Bones were scanned with a computed tomography device. The resulting images were saved in DICOM format and 3D models were created using a special software. 14 osteometric measurements were taken from the metacarpus and 12 from the digit bones. The results were evaluated statistically. As a result of the statistical evaluation, in the metacarpus; Smallest Breadth of diaphysis (Sd), Breadth of distal (Bd), Medio-lateral width of condylus medialis width of condylus medialis (WCM), Depth of proximal (Dp), Antero- posterior diameter of external trochlea of condylus medialis (Dem) and Antero-posterior diameter of internal trochlea of condylus medialis (Dim) parameters were found to be statistically significant between males and females (P<0.01). For phalanx media, GLpe and Bp measurement parameters were statistically significant between genders (P<0.05). The data obtained from the study will contribute to anatomy education, the classification of bones obtained in zoo-archaeological excavations, and the determined anatomical features that will contribute to surgical approaches.

    Objective: This study was carried out to investigate the anatomical, morphometric, topographic, and histological features of the uropygial gland in adult male and female budgerigars (Melopsittacus undulatus). Material-Method: For this study, the glandula uropygialis of fourteen adult budgerigars (7 male, 7 female) were used in the study. This glandular structure located between the caudal vertebrae and pygostyle was removed by careful dissection. Morphological and histological characteristics of the dissected glandula uropygialis were determined. In addition, morphometric measurements and index calculations were performed. Tissue samples taken to determine the histological structure of the gland were stained with Hematoxylin & Eosin (H&E), Masson Trichrome's and Periodic Acid Schiff-Alcian Blue. Result: In the study, it was determined that the gland structure was heart shaped and consisted of two lobes, a papilla and a draining duct system. Uropygial gland weight was determined as 1.57±0.96 g in male birds and 1.52±0.09 g in female birds. As a result of the statistical evaluation, there were significant differences between the sexes in the parameters of lobe width (P
