Early methods were limited in terms of their capacity to trace neuronal connections, but a breakthrough came with Camillo Golgi's \"black reaction\" staining method, later refined and extensively used by Santiago Ramón y Cajal. Cajal's observations supported the Neuron Theory, which proposed that neurons communicate via specialized points of contact, contradicting the prevailing Reticular Theory of a continuous neural network, which was supported by Golgi. This contrast is particularly intriguing because, although Golgi and Cajal used the same black reaction technique and similar microscopes, their interpretations of the microscopic world diverged significantly. An important consequence of the Neuron Theory was Cajal's Law of Dynamic Polarization, which proposed that neurons generally consist of three functionally distinct regions: a receptor apparatus (dendrites and soma), an emission apparatus (axon), and a distribution apparatus (terminal axonal arborization). He applied this principle across various parts of the nervous system and to different neuron types, enabling the generation of the first detailed circuit diagrams of the brain. Cajal's observations, concepts, and theories had a profound impact-not only on researchers of his time, but also on modern neuroscience. This article reflects on the early studies of neuronal connections, highlighting the scientific climate in which Golgi and Cajal initiated their groundbreaking research.","PeriodicalId":7816,"journal":{"name":"Anatomical Science International","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144061584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the clinical context, OP is the main factor responsible for the pain condition known as os peroneum syndrome, which usually manifests as pain in the lateral side of the foot. The purpose of this study is to provide a comprehensive synthesis of data regarding the prevalence of this ossicle. To find the pertinent articles, a thorough search of the major electronic bases was carried out. Data on imaging modality, sex distribution, prevalence, and geographic origin of OP were extracted. Throughout the study, the PRISMA guidelines were strictly followed. The AQUA tool was used to evaluate the reliability of the included studies. 26 studies (22,948 feet) were included in the meta-analysis. The pooled prevalence estimate (PPE) of OP was found to be 6.6% (95% CI: 5.1-8.5) (95% PI: 0.02-0.22) of the analyzed feet. In the X-ray-based subgroup, the PPE of OP was 6.7% (95% CI: 5.1-8.7) and in the cadaveric dissection-based subgroup was 11.1% (95% CI: 5.1-22.4). The highest prevalence of OP was observed in North America (8.6% (95% CI: 5.9-12.3)), followed by Europe (6.0%, (95% CI: 3.8-9.4)) and Asia (5.9% (95% CI: 3.9-9.0)). Os peroneum is a very common accessory ossicle which occurs approximately every fifteen feet. The highest prevalence of OP was found in the North American population. The occurrence of pain in the lateral part of the foot should draw physicians attention into considering a potential presence of OP during the differential diagnosis.","PeriodicalId":7816,"journal":{"name":"Anatomical Science International","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143960347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this preliminary study, we aimed to evaluate the morphological and morphometric features of the notch to enhance the diagnostic accuracy and therapeutic outcomes of nerve compression. This retrospective study was conducted using computed tomography images of the scapula obtained between January 1, 2022, and August 30, 2024. A total of 852 scapulae were evaluated, of which 448 belonged to males and 404 to females. Morphometric measurements included superior transverse diameter, middle transverse diameter, and maximal depth of the notch. In addition, the notch was classified using both the Polguj and Rengachary classification systems. When the measurement parameters were compared between genders, the values were higher in males; however, only the maximal depth showed a statistically significant difference (p < 0.05). According to the Polguj classification, Type 3 was the most common (63.38%). Based on the Rengachary classification, the U-shaped form was the most frequently observed (65.02%), while the J-shaped form was the rarest (3.41%). The foramen shape was detected in 5.75% of cases. The J-shaped variant was found to be approximately four times more common in males than in females. Knowledge of the anatomical variations of the notch is likely to be beneficial for both endoscopic and open surgical interventions in the suprascapular region. In particular, three-dimensional computed tomography imaging may be useful in preoperative planning for arthroscopic resection of ossified ligament.","PeriodicalId":7816,"journal":{"name":"Anatomical Science International","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143956567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to this variability, many studies have tried to describe the vascular anatomy of this anatomical entity using various classifications. It is hoped that the results of the present study may aid surgeons in increasing their anatomical knowledge relevant to colorectal surgeries. A retrospective analysis, including 75 consecutive patients, was conducted to assess the anatomical and morphometric variations of the LCA. Finally, a total of 67 LCAs were included in this study. The majority of the LCA originated directly (N = 48; 71.64%) or indirectly via the colo-sigmoid trunk (N = 18; 26.87%) from the inferior mesenteric artery (IMA). The most common variation of the LCA, according to the Yada, or analogical Wang, classification, was found to be Type I (N = 28; 50.00%). The median diameter of the LCA at its origin was found to be 2.12 mm (LQ = 1.77; HQ = 2.51). The median cross-sectional area of the LCA at its origin was set to be 3.38 mm2 (LQ = 2.29; HQ = 4.33). In conclusion, this study provides a detailed analysis of the anatomical and morphometric variations of the LCA, offering valuable insights for improving the safety and effectiveness of colorectal surgeries, particularly during procedures involving ligation of the IMA. These results emphasize the need for thorough preoperative imaging and anatomical understanding to minimize the risk of iatrogenic injury. Preserving the LCA during low ligation of the IMA is shown to be crucial for maintaining adequate blood supply to the remaining bowel, reducing the risk of ischemia, and ensuring better patient outcomes.","PeriodicalId":7816,"journal":{"name":"Anatomical Science International","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143962607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The accessory tendons were made visible by excising the surrounding tissues. A single bilateral accessory tendon arising from the fibularis brevis, passing through the canal within the fibularis tertius tendons and ending in the dorsal aponeurosis of the fifth toe, was observed as well as a bilateral single accessory tendon originating from the extensor hallucis longus and ending on the dorsomedial side of the first metatarsophalangeal joint capsule.

Additionally, we detected bilateral double tendon at the insertion of the fibularis tertius on the base of the fifth metatarsal bone. These four muscles are of clinical importance because the extensor hallucis longus is used in the correction of hallux varus deformity, the fibularis brevis is used for tendon transfer in Achilles tendon ruptures, and the fibularis tertius and the extensor digitorum longus tendons are used to correct drop foot deformity.

We think that it is necessary to discuss the reported asymmetry data by VolBrain. There might be inaccuracies or inconsistencies in how asymmetry is measured and reported. MRIs of the 138 healthy individuals (66 females, 72 males) were included. The VolBrain-HIPS pipeline was preferred for automatic segmentation. Alternative methods were recruited, including the total hippocampal volume for the adjustment of the volumetric data. Asymmetry index was accepted as the indicator of the magnitude of the asymmetry and negative asymmetry index data was positivized. Gender and side comparisons of the hippocampal data were presented not only for absolute measurement but also for the adjusted volumetric data. Comparisons for the magnitude of the asymmetry were carried out as well as the regression modeling based on age and gender. Hippocampus-adjusted volume information should also be considered when analyzing VolBrain data and making clinical or anatomical decisions. The asymmetry data produced by VolBrain should be considered as a magnitude scale of the asymmetry in individuals with right or left dominant hippocampus or hippocampus subfield. Alternative significant regression models were introduced to observe how the volumetric numerical composition of the hippocampus subfields changes with age.","PeriodicalId":7816,"journal":{"name":"Anatomical Science International","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143958936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current imaging report presents an atypical case of a dual origin of a left vertebral artery (LVA), which was identified incidentally during routine computed tomography angiography of a 51-year-old male patient. The typical LVA originated from the left subclavian artery (LSCA), and the other one was an aberrant LVA (ALVA) that arose from the aortic arch (AA) in between the left common carotid artery (LCCA) and the LSCA. The two vessels (LVA and ALVA) converged proximally to the transverse process of the C6 vertebra. The embryological explanation for this variant likely pertains to the persistence of primitive dorsal aortic segments and intersegmental arteries. Although rare, with a prevalence of 0.1%, the occurrence of LVA double origin may have significant clinical implications, including alterations in hemodynamics, an increased risk of VA dissection, and complications during surgical or endovascular procedures. The identification of such variants through preoperative imaging is essential to prevent iatrogenic complications.","PeriodicalId":7816,"journal":{"name":"Anatomical Science International","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143958196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research on gender effects on learning and skill acquisition has yielded contradictory results, particularly in anatomy learning among undergraduate medical students. While various dissection course settings have been evaluated, gender-specific differences have largely been overlooked. This study examined gender differences in several aspects of anatomy education. First, the ability of undergraduate medical students to identify anatomical structures was assessed to determine gender differences in learning gains. Second, learning outcomes were compared between a 3-month and a 1-month regional anatomy course, with attention to gender. Third, knowledge retention was evaluated at 6- and 12-month follow-ups. Finally, student perceptions of different embalming methods for anatomy learning were assessed with a focus on gender. Minor differences were observed between genders across different regions in learning gains. Scores from the 3-month course were higher than those from the 1-month course, regardless of gender, particularly for the neck, thorax, and abdomen. A significant knowledge gain was noted in abdominal anatomy at the 6- and 12-month follow-up: scores improved by 56% in females and by 68% in males. The comparison of Thiel- versus ethanol-based embalming revealed gender differences regarding tissue pliability and the utility of tissues for achieving learning objectives. In conclusion, subtle differences appear to exist between female and male students in terms of perceptions and learning outcomes in gross anatomy dissection courses. These findings will be useful in developing new curricula for undergraduate medical students, taking into account gender differences in the context of regional anatomy dissection courses.","PeriodicalId":7816,"journal":{"name":"Anatomical Science International","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143787542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
