Background: Median nerve is generally formed in axilla, as one of the branch of brachial plexus. It is formed by the union of medial and lateral roots which are the branches of me­dial and lateral cord respectively. The knowledge of origin, course and area of distribution of median nerve is important for the anatomist, the neurologist and also for correction of traumatic injuries that are related to brachial plexus. The main objective of this study is to observe different variations in median nerve formation in cadavers. Methods: A descriptive cross-sectional study was conducted in 25 formalin fixed adult human ca­davers in the Department of Anatomy, KIST Medical College and Teaching Hospital, Lalitpur Ethical approval was taken. Altogether, 50 specimens were enrolled in the study by convenient sampling method. The calculation was done using Statistical Package for Social Sciences version 20 (SPSS). Results: In this study the formation of median nerve was observed to be normal in 78% of the cases. In 20% cases three roots were forming the median nerve and in 2% cases four roots were present. Among these variations in 18% cases the additional roots were observed to be given by the lateral cord of the brachial plexus. Conclusions: This study concludes that most of the median nerve forms in axilla by the union of two roots with few variations.

Background: The sciatic nerve is formed in the pelvic cavity and leaves the cavity through the greater sciatic foramen below the piriformis muscle. It terminates by giving tibial and common peroneal (fibular) nerve near the superior angle of the popliteal fossa. Awareness of variations in bifurcation of sciatic nerve is significant during deep intramuscular gluteal injections, clinical conditions such as piriformis syndrome, sciatica, coccygodynia and muscle atrophy. The main objective of this study was to highlight the site of bifurcation of sciatic nerve. Methods: An observational cross–sectional study was performed in the Department of Anatomy of KIST medical college & Teaching Hospital, Lalitpur, Nepal. The data was collected after ethical approval from Institutional Review Committee. 50 specimens were taken in the study by convenient sampling method. Sciatic nerve was observed in respect to its site of bifurcation. Results: Out of 50 lower limbs, in 30 specimens (60%) the sciatic nerve showed bifurcation near the superior angle of popliteal fossa. 20 lower limbs (40%) showed variations,of which eight limbs (16%) showed division of nerve prior to its exit in the gluteal region, eight limb (16%) showed division in upper 2/3rd of back of thigh and four limbs (8%) showed division of the nerve in the popliteal fossa. Conclusions: This study concludes that the majority of sciatic nerve divides at the superior angle of the popliteal fossa while some divided into other regions such as pelvis, thigh & popliteal fossa.

Introduction: The radial artery is commonly originated from the brachial artery in the cubital fossaat the level of the neck of the radius. It is the artery of choice for coronary artery angiography,percutaneous coronary artery intervention, cannulation, and others. Radial artery anomalies likehigh origin, tortuosity, and accessory branches are associated with the failure of such procedures.The main objective of this study is to study the variation in origin and course of the radial artery incadavers. Methods: A descriptive cross-sectional study was conducted in 27 formalin-fixed adult humancadavers in the Department of Anatomy, KIST Medical College and Teaching Hospital, Lalitpur,Nepal, from 2075/4/2 to 2076/4/2. Ethical approval was taken on date 02/04/2075 (IRC No.2074/75/38). Altogether, 53 specimens were enrolled in the study by convenience sampling method.Point estimate at 95% Confidence Interval was done for binary data along with frequency andproportion. The data was analyzed by and Statistical Package for the Social Sciences version 20. Results: Out of of 53 upper limbs, forty-six (86.79%) specimens, the origin of the radial artery wasobserved to be normal in the cubital fossa, 34.5±6.31mm below the level of the intercondylar lineof the humerus with the superficial course. In seven (13.21%) specimens, the radial artery showedvariation in the origin. Among them, variations in origin were found to be from sites like the axilla,upper-middle, and lower part of the arm. One cadaver showed a tortuous radial artery bilaterally. Conclusions: This study concludes that most of the radial artery originates in the cubital fossa fromthe brachial artery with few variations.

Background: Total body height is important for calculating body mass index, drug dosages calculations and other patient care issues. Total height estimation from different body measurements are surrogate measures of stature which is very useful when only fragmentary remains of a human body are found. Aims and Objective: The aim of this study is to develop the relationship of total body height with arm span, leg length and trunk length in Nepalese Medical students. Materials and Methods: A descriptive cross-sectional study was conducted in 441 medical students in the Department of Anatomy, KIST Medical College and Teaching Hospital, Lalitpur, Nepal from January to June 2019 after taking ethical approval. Body height, arm span, leg length and trunk length were measured and regression and correlation analysis between them were done. Results: The mean standing height, arm span, trunk length and leg length were 161.85±9.14, 165.37±10.5, 84.80±4.23, 77.06±6.5 cm respectively. Correlation coefficient of standing height with arm span, trunk length and leg length were 0.87, 0.76 and 0.90 respectively. Regression coefficient for standing height and trunk length, standing height and arm span and standing height and leg length were 1.65, 0.76 and 1.27 respectively. Regression equations for standing height were determined. Conclusions: Total body height shows strong correlation with arm span, trunk length and leg length.
