WebbSynaptic transmission allows electrical impulses to travel unidirectionally. Neurotransmitters are released on one side and the receptors located on the other, making the direction of the impulse precise. This is important because it allows for reflexes and other automatic responses to be “programmed” in the hard-wiring of our nervous system.

WebbIn FES, small electrical impulses are applied to the nerves that supply the affected muscles using either self-adhesive electrodes placed on the skin or implanted electrodes on the nerve or muscle close to the motor point. The electrical current generates an electric field between the pair of electrodes (Fig. 21.1), and, with the right conditions, … Webb2 mars 2024 · Because nerve transmission involves changes in voltage (charge) across the plasma membrane, these ion channels respond to the voltage changes and are, therefore, referred to as voltage-gated ion channels. The resting membrane potential of a neuron is maintained by the differential distribution of K + and Na + ions.
