Anatomical variation in the formation of the median and musculocutaneous nerves.

Entre los nervios mediano y musculocutáneo se establecen comunicaciones que determinan variaciones en la formación de ambas estructuras nerviosas. Patologías o traumas de las regione axilar o braquial que deriven en compromiso de éstos elementos nerviosos, hace fundamental el conocimiento de ellos para la práctica clínica o quirúrgica. En este trabajo presentamos un caso de anomalía en la formación de los nervios mediano y musculocutáneo, que determina una variable en la comunicación entre ambos nervios terminales.Between the median  and musculocutaneous nerves are established communications that determine variations in the formation of both neural structures. The knowledge of them is of fundamental importance in clinical and surgical practice, in the presence of diseases or trauma of the axillary or brachial arteries and whose intervention resulting in compromise of these neural elements. We present a case of abnormality in the formation of the median and musculocutaneous nerves, which determined the establishment a variable communication between both terminals trunks

Relation between Academic Performance and Methodological Strategies in Two Groups of Beginner Students in the Occupational Therapy and Nutrition - Dietetics Careers at the Universidad Mayor in Temuco

The aim of this study was to determine if first year students learning results, of the Occupational Therapy career at the Universidad Mayor in the course subject of anatomy, were correlated from the application of cooperative work methodologies. The investigation is quantitative and analytical. The methodology of a group of experts and an experimental group was applied. We observed that the control group as well as the experimental group had a similar academic weight. When cooperative methodologies were applied the experimental group obtained a higher performance level in comparison with the performance level of the control group
