Several types of fibre bundles superficial to the pyramids have been described in early and mid 20th century. Recently, few of these have been studied in detail. Objective of present study was to observe the morphology of AEAF in the Indian population. Distinct AEAF were noted in 13 out of 50 brain specimens. Based on their relation to olive, AEAF were further classified as supraolivary, preolivary and supraolivary fibers and their prevalence noted as 25%, 15%, and 9% respectively. Supraolivary and preolivary fibers were present together in 9 brainstem sides, while co-presence of preolivary and circumolivary fibers was noted in only 1 side. All three types of fibres were observed together in 5 brainstem sides. When present bilaterally, supraolivary and preolivary fibers were seen in 92.30% and 66.66% of brainstem respectively, while circumolivary fibers were seen bilaterally in 28.57% of brainstem. Supraolivary and circumolivary fibers exhibited variable morphology as single, double and multiple fiber bundles. Morphometric analysis revealed presence of thicker supraolivary fiber bundle on right side, while thicker circumolivary fiber bundles were noted on left side. Present study will add to knowledge of this variable fiber bundle pattern, which has been reported to play an important role in regulation of crucial physiological functions such as breathing and cardiorespiratory mechanisms. These observations open avenues for further research into developmental factors involved in migration of neurons from the rhombic lip.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":"86-92"},"PeriodicalIF":1.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11933802/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142646781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most institutions successfully transitioned from traditional in-person teaching methods, to various distance-learning strategies. Since virtual reality (VR) offers immersive three-dimensional (3D) experiences, this study investigated students' experiences regarding the capacity of VR to support distance-learning of anatomy. Using the VR application, 3D Organon Virtual Reality Anatomy, anatomy instructors pre-recorded learning content as 360-degree videos with live voice-over and integrated it into the teaching material of the MBBS first-year abdomen, pelvis, and perineum-structure and function course. A 19-item 5-point Likert scale questionnaire, comprising of two major categories, \"VR experience in anatomy lessons\" and \"VR in anatomy lessons vs. traditional cadaveric dissection\" was disseminated. Post-evaluation analysis revealed a response rate of 63.5%. Almost 70% of students agreed that VR was instrumental in solidifying their theoretical understanding and improved spatial awareness with better retention of anatomical relationships. Approximately 50% wanted to continue using VR even if instruction becomes onsite. Though 72% of participants agree that VR addressed the session learning objectives only 24% agree that it is similar or better than cadaveric dissection, thus preferring cadaveric dissection to VR. Only 12.1% agree that VR is more beneficial to cadaveric dissection. Our exploration into the integration of VR technology in anatomy teaching has revealed promising opportunities. While VR can augment traditional teaching methods in unprecedented times such as war, floods or global pandemic, it should not replace hands-on cadaveric learning entirely, but rather complement existing approaches.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":"112-121"},"PeriodicalIF":1.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11933808/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142765556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This comparative study aimed to examine the differences in PMs morphology between the right and left ventricles, focusing on their number, location, and shape. A total of 38 grossly normal hearts from donated bodies were dissected, and the number, location, and shape of PMs in both ventricles were observed. In this study, the left ventricle predominantly exhibited a single PM with 71.05% on the sternocostal surface and 57.89% on the diaphragmatic surface. The right ventricle showed a higher prevalence of single PM, at 89.47% on the sternocostal surface and 63.16% on the diaphragmatic surface. Broad-based shape of the PM emerged as the predominant variant, constituting 55.26% and 44.73% on the sternocostal and diaphragmatic surfaces of the left ventricle, respectively. In contrast, conical-shaped PM predominated in the right ventricle. Unique findings included \"H\" and \"b\" shaped muscles, conjoint PMs were observed exclusively in the left ventricle, and small papillary projections with direct tendinous cord attachment in the right ventricle. A distinct webbed shaped configuration of PM was exclusively observed in the right ventricle in only one specimen. No significant difference (P=0.84) was noted in muscle bellies between ventricular surfaces. This study emphasizes the complexity and variability in PM morphology, highlighting the importance of a thorough understanding of these structures for cardiothoracic surgeons, radiologists, and cardiologists to enhance interventional techniques.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":"44-53"},"PeriodicalIF":1.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11933809/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142646777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These drugs may reduce the endogenous estrogen production in the cerebellum. Prolonged use has been associated with symptoms such as ataxia, poorer balance performance and diminished verbal memory, suggesting impaired cerebellar function. Thus, this study sought to outline the structural basis for the cerebellar deficits observed. Twenty-seven male rats (3 baseline, 15 experimental, 9 control) aged three months were recruited with the intervention group receiving 0.5 mg/kg of letrozole daily for 50 days by oral gavage while the control group received normal saline. Their cerebella were harvested for histological processing on days 20, 35, and 50. Photomicrographs were taken and analysed using Fiji ImageJ software. The dendritic spine densities and Purkinje linear densities were coded and analyzed using IBM SPSS Statistics version 25.0. A P-value of ≤0.05 was considered significant. A temporal decline in the Purkinje linear density as well as pyknosis and cytoplasmic eosinophilia was noted in the intervention group (P=0.165). Further, the dendritic spine density of the Purkinje neurons in the intervention group was markedly reduced (P=0.01). The reduction in the linear cell density and the dendritic spine density of the Purkinje cells following letrozole administration may provide an anatomical basis for the functional cerebellar deficits seen in chronic aromatase inhibitor use.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":"76-85"},"PeriodicalIF":1.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11933817/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142543204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The increasing use of image processing techniques in the medical field provides a more efficient and convenient alternative. This study used image processing methods to analyze area ratios and percent porosity of the acetabulum and femoral head, with a statistical evaluation of the relationship between these parameters and age at a 90% confidence level (α=0.10). The dataset comprised images from 167 skeletons including 59 females aged 30 to 88 and 108 males aged 28 to 97. The analysis revealed a significant relationship between percent porosity and age in males, both in the acetabulum and femoral head, with P-values below 0.10 but this relationship was not observed in females. A significant relationship between area ratio and age was found in the femoral head region for both genders but not in the acetabulum.

This review aimed to review the surgical anatomy of the EF, including their embryology and radiology. Although the frontoethmoidal sutures mostly have two foramina passing through them, there are reports of single foramen or multiple, up to six foramina. These foramina provide a passage for the ethmoidal arteries and nerves, branches of ophthalmic arteries and nerves. The surgical guideline \"24-12-6\" is based on the approximate distance between the anterior lacrimal crest, the anterior and posterior ethmoidal arteries, and the optic canal, commonly used to navigate this area. However, some studies from various populations defined different ratios. Embryologically, the EF were formed by the union of intramembranous ossified frontal bones and endochondral ossified ethmoid bones. EF and neurovascular structures can be identified in computed tomography even in the 3 mm sectional intervals. A comprehensive anatomical understanding of EF will help clinicians improve surgical guidelines and ultimately reduce the risk of complications.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":"1-7"},"PeriodicalIF":1.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11933806/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142765578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
