• Resumen

  • In Electromyography studies, the motor unit is considered as the anatomical and functional unit responsible of the electrical activityrelated to the contraction of the skeletal muscle. This paper is aimed at showing biomedical engineering master students how to modeland study the electrical potentials produced by the activation of the motor unit. The proposed model is based on a mathematicalconcept familiar to engineers, the convolution. By using computer simulations based on this model, the effects of changes in the motorunit parameters on the characteristics of generated electrical signal are illustrated. The paper is useful in showing the students how toidentify the different aspects involved in the analysis of biological phenomena.
