RESUMO
Introduction: Fetal biometric parameters are very often utilized for calculating gestational age. The pancreas is a gland with dual functions in our body – exocrine and endocrine, with the latter component being very often discussed in the context of diabetes mellitus. Through evaluation of variations in morphometry in relation to different gestational ages, the research intends to draw attention to various associated developmental correlations that were not mentioned in previous studies. MaterialsandMethods: The current research was carried out on 30 fetuses after obtaining due approval from Institute’s Ethical Committee. Fetuses were divided into different gestational age groups and morphometric parameters such as crown‑rump length, crown heel length, head circumference, abdomen circumference, chest circumference, hand length, and Foot Length (FL) were noted by measuring with nylon thread in centimetres. Fetal pancreases were removed after stepwise dissection and pancreatic weight along with length and thickness was measured by Vernier calipers. All the parameters were then compared within different gestational age groups. Results: All the parameters and the age group of fetuses were positively correlated and showed statistical significance.Conclusion: The study would add substantial knowledge in the areas of pancreatic regeneration, surgical pancreatectomy, and treatment protocols for diabetes mellitus and pancreatic cancer. Through evaluation of variations in morphometry in relation to different gestational ages, the research intends to draw attention to various associated developmental correlations
RESUMO
Abstract During dissection conducted in an anatomy department of the right upper limb of the cadaver of a 70-year-old male, both origin and course of the radial and ulnar arteries were found to be anomalous. After descending 5.5 cm from the lower border of the teres major, the brachial artery anomalously bifurcated into a radial artery medially and an ulnar artery laterally. In the arm, the ulnar artery lay lateral to the median nerve. It followed a normal course in the forearm. The radial artery was medial to the median nerve in the arm and then, at the level of the medial epicondyle, it crossed from the medial to the lateral side of the forearm, superficial to the flexor muscles. The course of the radial artery was superficial and tortuous throughout the arm and forearm. The variations of radial and ulnar arteries described above were associated with anomalous formation and course of the median nerve in the arm. Knowledge of neurovascular anomalies are important for vascular surgeons and radiologists.
Resumo Durante dissecção de membro superior direito de um cadáver de 70 anos, do sexo masculino, conduzida em um departamento de anatomia, foram observadas anomalias tanto na origem quanto no curso das artérias radial e ulnar. Após descer 5,5 cm desde a borda inferior do músculo redondo maior, a artéria braquial anomalamente se bifurcava em uma artéria radial medialmente, e em uma artéria ulnar lateralmente. No braço, a artéria ulnar se encontrava ao lado do nervo mediano, e seguia um curso normal no antebraço. A artéria radial se encontrava medialmente ao nervo mediano no braço e, então, no nível do epicôndilo medial, ela cruzava do lado medial para o lado lateral do antebraço, na superfície dos músculos flexores. O curso da artéria radial era superficial e tortuoso em todo o braço e antebraço. As variações das artérias radial e ulnar aqui descritas foram associadas a formação e curso anômalos do nervo mediano no braço. Conhecimento sobre anomalias neurovasculares são importantes para cirurgiões vasculares e radiologistas.
