• Resumen

  • Neurons generate electric signals to carry information to different parts of our bodies which are able to respond to ambient and externa stimuli, as the muscle tissue that is responsible for movement. The way the neurons generate and transmit the electric impulse is based on the different electrochemical gradients through the membranes, known as resting and action potentials. Those potentials can be measured, and they are created thanks to ionic pumps that transport specifically diferent ions, increasing membrane’s permeability to it. It is important to take into consideration both components of an electrochemical gradient:

    the electrical gradient, due to a different distribution of charges, and the chemical one, due to different concentration of species at both sides of the membrane
