Expression of cadherins and some connective tissue components in cow uterus and placenta during pregnancy.

The implantation and placental development processes are regulated with cell adhesion molecules and remodeling of the maternal endometrium's extracellular matrices (ECM) and fetal chorion. This study aimed to investigate the distribution and localization of some classical cadherins (E-, N-, and P-cadherins) and extracellular matrix components collagen type 5α1, fibronectin, and laminin in the cow placentomes during pregnancy using immunohistochemical and Western blotting analyses. The study results confirmed the expression of E- and P-cadherins, collagen type Vα1 (COLVα1), fibronectin, and laminin in the cow placentomes, but not N-cadherin.

Morphological Aspects and Microscopic Analyses of Fibrous Tunic and Uveal Components in Bovine Eye.

Comparative morphology and physiology of the vocal production apparatus and the brain in the extant primates.

Objective data mainly from the comparative anatomy of various organs related to human speech and language is considered to unearth clues about the mechanisms behind language development. The two organs of the larynx and hyoid bone are considered to have evolved towards suitable positions and forms in preparation for the occurrence of the large repertoire of vocalization necessary for human speech. However, some researchers have asserted that there is no significant difference of these organs between humans and non-human primates.

The expressions of some metabolic hormones (leptin, ghrelin and obestatin) in the tissues of sheep tongue.

In this study, we aimed to observe the localization and expression of peptide hormones-leptin, ghrelin and obestatin-in the sheep tongue by immunohistochemistry. For that purpose, tongues of ten adult sheep were used. Leptin expression of moderate intensity was observed in the basal and parabasal epithelial cells of the luminal epithelium, and leptin was strongly expressed in the taste buds of the circumvallate and fungiform papillae and in von Ebner's glands.

The 38-item instrument tool developed by the researchers consisted of three sections and was administered to volunteer student participants.

Papillary Architecture and Functional Characterization of Mucosubstances in the Sheep Tongue.

This research aimed to reveal the general morphology and topographic distribution of lingual papillae, epithelial characteristics, mucosal structure, and glands with their mucin content in the sheep tongue, with consideration of species-specific characteristics. The tongues of ten sheep were analyzed for this purpose. Filiform and fungiform papillae existed within the borders of the ventral surface of the lingual apex.

Morphofunctional structure of the lingual papillae in three species of South American Camelids: Alpaca, guanaco, and llama.

The aim of this study was to compare the anatomical and functional characteristics of the lingual papilla among the Camelidae. For this purpose, tongues of alpaca, guanaco, and llama were used. Numerous long and thin filiform papillae were located in the median groove and none were detected on the rest of the dorsal surface of the lingual apex in alpaca.

Functional characteristics of the growth factor receptor family and some ligands in the oropharyngeal cavity of the Chukar partridge (Alectoris chukar).

1. The aim of the present study is to describe, immunohistochemically, the expression and cell type localisation of growth factor receptors and some of their ligands in the oropharyngeal organs of the Chukar partridge. 2.

Morphology of the lingual surface of South American fur seal (Arctocephalus australis) and sea lion (Otaria flavescens).

In this study, we aimed to describe the morphological characteristics of the lingual papillae in two species of Otariidae family by stereomicroscopy and scanning electron microscopy. We used tongues of two South American Otariidae species. The tongues were elongated and terminated in bifid apex and there was no median sulcus on the dorsal lingual surface.

Functional anatomy of the syrinx of the chukar partridge (Galliformes: Alectoris chukar) as a model for phonation research.

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.

Function-related morphological characteristics and specialized structures of the avian tongue.

As a reflection of different life styles and environment, the tongue of vertebrates, which plays a major role in the intake and swallowing of food, displays significant morphological differences. The gross form and microscopic structure of the avian tongue differ greatly according to lifestyle. The avian tongue plays a fundamental role in many functions such as capturing, filtering, sucking and manipulating food in order to compensate absence of subsidiary organs like teeth in the oropharyngeal cavity.

The branching pattern of the aortic arch in the long-legged buzzard (Buteo rufinus Cretzschmar 1829).

The aim of this study was to investigate the vascular branching morphology of the aortic arch in the long-legged buzzard. For this purpose, two long-legged buzzards were evaluated in this study. The latex injection method was used to investigate the branching of the aortic arch.

Inner ventricular structures and valves of the heart in white rhinoceros (Ceratotherium simum).

In this study, we describe the internal structures of both ventricles and the valvular apparatus of the heart of the white rhino. In the right of the heart, three papillary muscles were found in septal and marginal walls and m. papillaris magnus was the biggest.

Anatomical and scanning electron microscopic characteristics of the tongue in the pampas deer (Cervidae: Ozotoceros bezoarticus, Linnaeus 1758).

This study represents the first definitive anatomical description of the tongue and lingual papillae of the pampas deer and compares the different information on the morphology of the other ruminant species available in the literature. In this study, the tongues of four adult and one fetal deer were used. The tongue was elongated with an oval or rounded apex.
