The transverse sinus canal/groove, located near the attachment margin of the tentorium cerebelli, houses the transverse venous sinus. During surgical procedures, it is essential to understand the anatomical position of the osseous tentorium cerebelli and transverse venous sinus using the surface structure of the skull as a landmark. This study compared the positional variation of the attachment site of the osseous tentorium cerebelli and transverse sinus canal/groove relative to the external landmarks of the skull, specifically the external occipital protuberance and nuchal crest in small dogs. We analysed computerised tomography data from 23 client-owned dogs of four small breeds without brain or skull lesions. Using sagittal plane images from computed tomography (CT), the osseous tentorium cerebelli deviation distance (OTCDD) and the transverse sinus canal or groove deviation distance (TSCGDD) from external landmarks were measured. Both OTCDD and TSCGDD exhibited interindividual variation. In the interbreed comparison, the OTCDD was significantly greater in Chihuahuas than in Toy Poodles and Miniature Dachshunds. A strong correlation was observed between OTCDD and TSCGDD. This study demonstrated both interindividual and interbreed diversity in the anatomical positioning of the osseous tentorium cerebelli and transverse sinus canal/groove. Nevertheless, these structures consistently maintained a close spatial relationship. The findings contribute to a more detailed anatomical understanding of the skull in small-breed dogs and may assist in optimising craniectomy procedures.\u0000 </div>","PeriodicalId":49290,"journal":{"name":"Anatomia Histologia Embryologia","volume":"54 6","pages":""},"PeriodicalIF":1.0,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145193932","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}

In recent years, interest in these therapies has grown, and they have gained increasing importance. Many musculoskeletal disorders in dogs are located in the region of the trunk, but knowledge about the course and branching of the cutaneous branches remains limited. This study presents a morphological analysis of the innervation pattern of the first cutaneous branch of the spinal dorsal nerve branches in 14 dogs. The dissection was performed in four layers to trace the cutaneous branches from the intervertebral foramen to their target area. The distances covered in each layer were measured and described using the Caudal Shift Index (CSIn). For this purpose, the ‘back region’ was defined as a dimensional unit, representing the distance between the spinous processes of two consecutive vertebrae within the examination area from the ninth thoracic (Th9) to the seventh lumbar (L7) vertebra. The results showed that the cutaneous branches innervating the lumbar region originated, on average, between Th11 and L4. The mean CSIn-S was three back regions, indicating a distance equivalent to the length of three vertebral bodies between the nerve's origin at the foramen and the skin entry. In conclusion, these findings demonstrate consistency in the caudal shift of the cutaneous branches between Th9 and L4, with a high degree of symmetry between both sides of the body. These findings should be considered in therapeutic treatments.","PeriodicalId":49290,"journal":{"name":"Anatomia Histologia Embryologia","volume":"54 5","pages":""},"PeriodicalIF":1.0,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ahe.70063","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145062800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of the present study was to establish normal quantitative parameters for the cerebellum during intrauterine development in sheep, using unbiased design-based stereological methods. Twenty sheep embryos were divided into four gestational age groups (9–11, 12–14, 15–17 and 18–20 weeks of gestation). The orientator method was used to obtain isotropic, uniform and random sections. The fractional volume of white matter, grey matter and different layers was estimated by a point-counting system. The cerebellar surface area was estimated through the use of test lines. The total volume of the cerebellum increased from 0.1142 ± 0.02644 cm3 to 1.4717 ± 0.3558 cm3 during development. The volume of white matter increased from 0.0785 ± 0.02616 cm3 to 0.5316 ± 0.12677 cm3, and the volume of grey matter showed an increase from 0.0785 ± 0.02616 cm3 to 0.5316 ± 0.12677 cm3.

As described in other primates, branching longitudinal folds and a tunica muscularis were seen in uterine tubes in M. marcai.

In macroscopic examinations, it was determined that the yak rhinarium consists of dark, moist and hairless skin located between the nostrils and the upper lip and that it features a philtrum in the upper lip region. In SEM examinations, the skin in this region was composed of epidermis and dermis layers and that the skin surface had areas of different sizes separated by primary grooves containing single, double or triple epidermal domes. In triple staining, it was determined that the skin was composed of epidermis, dermis and hypodermis. The dermis and epidermis layers were tightly connected to each other, and the stratum corneum was thick in the epidermis layer, while connective tissue threads and serous glands and ducts were dense in the dermis layer. According to the findings obtained from the study, it was concluded that the tip of the yak's nose has differentiated to adapt to high altitude, cold and harsh weather conditions; the philtrum seen in the upper lip section of the rhinarium can be used to distinguish yak from other cattle breeds, and the dome areas of different shapes and numbers seen on the epidermal surface can be used in the individual identification of animals.\u0000 </div>","PeriodicalId":49290,"journal":{"name":"Anatomia Histologia Embryologia","volume":"54 5","pages":""},"PeriodicalIF":1.0,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144897503","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}

Type I (red) and type III (yellow-green) collagen fibres were distributed throughout the stroma and erectile bodies of the penis. Periodic acid-Schiff (PAS)-positive staining was observed in the epithelial cells at the base of the hair follicles, and immunohistochemical immunolabelling for androgen receptors (AR) and oestrogen receptors (ER) was detected in all cells of the transitional epithelium of the penile urethra.

The immunohistochemistry results from postnatal day 1 (P1) to P7 indicate that both blood and lymphatic vessels extend into the uterine muscle layer without glandular bud formation, accompanied by YAP1 mainly expressing in the cytoplasm of the uterus. From P8 to P10, the number of blood vessels and lymphatic vessels increases, glandular buds begin to form, and YAP1 nuclear expression rises. By P21, the tissue structure of the uterus resembles that of adults; YAP1 expression sharply decreases. By P28, YAP1 expression is nearly absent. We demonstrate that YAP1 expression dynamically shifts from cytoplasmic to nuclear localisation during postnatal uterine development in mice, correlating with lymphatic vessel invasion into the myometrium (P1–P10) and glandular maturation (P8–P21). Vascular development precedes lymphangiogenesis, suggesting angiogenesis-dependent nutrient delivery is critical for early uterine growth.

Juvenile specimens lacked clear layering, suggesting ongoing endochondral ossification. One or more smooth, regular tidemarks separated the uncalcified and calcified fibrocartilage, while the margins separating the ligament and bone from the fibrocartilage layer showed pronounced irregular interdigitations. Mean cellularity, fibrocartilage thickness and interdigitation size and shape varied among specimens.
