For this purpose, eight adult animals were used. Macroscopic analyses were carried out on the organs that make up the respiratory system, which confirmed the existence of four cartilages of the larynx, trachea with an average of 37 incomplete tracheal cartilages and lung, highlighting the absence of the accessory pulmonary lobe being composed only of the right cranial and caudal, left cranial and caudal lobes. After the standard protocol, microscopic analyses of fragments of the organs evidenced in the macroscopic study were carried out, using optical microscopy and scanning electron microscopy, in addition to chest x-rays with positive contrast media through orotracheal intubation. Finally, we conclude that microscopically the respiratory system of the two-toed sloth is like other Xenarthra and some domestic animals. Macroscopically, the nose is like <i>Choloepus hoffmanni</i>, the nasal cavity to other species of Xenarthra already described in addition to domestic animals. The trachea differs from other species in terms of the number of tracheal rings and extension. As for the lungs, they were the ones that differed most when compared to other Xenarthra and to domestic animals as it was the species with the least lobation.</p>\u0000 </div>","PeriodicalId":49290,"journal":{"name":"Anatomia Histologia Embryologia","volume":"54 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Computed tomography images of a total of 16 adult and healthy Van cats, eight females and eight males, were used in the study. Three-dimensional modelling of the images and osteometric measurements were obtained using MIMICS 20.1 software. When the osteometric data of the bones were analysed, it was observed that all of the morphometric measurements of metatarsal, phalanx media, phalanx distalis and phalanx proximalis bones, except the greatest breadth of the distal end of the phanax proximalis-III, the greatest breadth of the proximal end of the right phalanx proximalis-II, left phalanx proximalis-IV and left phalanx proximalis-V, were higher in male cats than females. The length order of the metatarsal bones in Van cats was found as IV, III, V and II, respectively. It was determined that there were positive and significant correlations between the osteometric measurement parameters of metatarsal and phalangeal bones with age and body weight. In conclusion, basic morphological images and osteometric data of the metatarsal and phalangeal bones in Van cats were obtained.

The objective of this study is to describe the digestive tract morphology of these birds. Six cockatiels were dissected and all parts of the digestive tract were measured and processed for histological analysis. The measured data were highly variable for some parts. The oesophagus is divided into a cervical part with the ingluvies (crop) and celomic portion. Mucosal folds and a stratified non-cornified epithelium in the oesophagus and ingluvies were observed. No oesophageal glands were observed in the cervical portion and ingluvies, however, in the celomic portion submucosal glands were abundant. The cockatiel's stomach is subdivided into a glandular and a muscular part. The glandular stomach has a simple columnar epithelium with PAS+ cells and gastric glands. The muscular stomach exhibits a gastric cuticle, and simple columnar epithelium with branched tubular glands, and its muscular layers are organised in inner circular and outer longitudinal bundles. The intestine of cockatiels is subdivided in the small intestine with duodenum, jejunum, ileum and the short large intestine is represented by the colorectum. The <i>Tunica mucosa</i> of the small intestine forms villi lined with simple columnar epithelium with goblet cells. Simple tubular glands extend into the lamina propria mucosae. The wall of the large intestine contains simple tubular glands and a circular and thin layer of smooth muscles.
