Introduction: The femoral nerve is one of the vital nerves of the thigh region, which has importance in various fields of clinical areas, as well as in the field of Anatomy and the research areas. Femoral nerve blockade plays an important role in surgical interventions of the anterior thigh. Although the femoral nerve is superficial and easier to identify, a profound knowledge regarding the dimensions of the nerve is inevitable to perform successful surgeries and blockades. Objective: The describing study was an attempt to analyze the different dimensions of the femoral nerve in the thigh region of the Malaysian cadavers with relevant clinical implications, as there is a paucity of these studies involving Malaysian cadavers has been reported. Methods: This study had been conducted with the involvement of 78 adult lower limb specimens (cadaveric and disarticulated) of both genders and different ethnicity. Result: The average length of the femoral nerve from the inguinal ligament (IL) till its division and the width at the IL resembled the previous studies conducted on other geographical locations. The width at the division was similar to that of the IL level. The thickness at the IL was 1.32 ± 0.21 (right) and 1.29 ± 0.17 (left); and at the division was 1.50 ± 0.196 (right) and 1.43 ± 0.16 (left). The circumference of the nerve at the IL was 25.44 ± 1.26 (right) and 25.98 ± 0.89 (left); and that at the division was 25.65 ± 1.32 (right) and 25.66 ± 1.25 (left). Conclusion: The knowledge of the morphometric anatomy of the femoral nerve in the thigh region will not only assist neurologists and future researchers but also facilitate clinicians to prevent misdiagnoses and iatrogenic neurological damage.

Background: The cerebral ventricles are fluid-filled cavities within the brain crucial for cerebrospinal fluid (CSF) circulation. Assessing their size is important for diagnosing neurological conditions. This study aims to establish reference ranges for the morphometry (size and shape) of the third and fourth ventricles in healthy Bangladeshi adults using Magnetic Resonance Imaging (MRI). Methods: A cross-sectional study was conducted on 200 healthy adults (100 males and 100 females) aged 18-60 years. High-resolution T1-weighted MRI scans were obtained, and morphometric measurements of the third and fourth ventricles were performed. The parameters measured included the width, length, and height of the ventricles. Statistical analysis was carried out to assess the variations in ventricular dimensions across different age groups and between sexes. Results: The study found that the mean dimensions of the third and fourth ventricles in the Bangladeshi population are consistent with existing data from other populations, with some variations. Significant differences were observed in the dimensions of both ventricles between males and females, with males showing slightly larger measurements. Age-related changes in ventricular size were also noted, with a trend towards increased dimensions in older age groups, indicating possible age-associated atrophy. Conclusion: This study provides valuable baseline data for the third and fourth ventricular dimensions in the adult Bangladeshi population. These normative values can aid in the diagnostic assessment of various neurological conditions and contribute to a better understanding of intracranial anatomical variations in this demographic. Further research with a larger sample size and inclusion of pathological cases is recommended to enhance the clinical applicability of these findings. This study has provided valuable reference data for interpreting ventricle size in Bangladeshi adults undergoing MRI scans. Deviations from these norms might warrant further investigation for potential neurological issues. The findings can contribute to improved diagnosis and management of neurological conditions in Bangladesh.
