WebGeneration and Transmission of the Nerve Impulse. A nerve impulse is generated when the stimulus is strong. This stimulus triggers the electrical and chemical changes in the neuron. As mentioned already there are different ions on either side of the cell membrane. The exterior side has sodium ions that are positively charged and are more in number. WebNerve impulses travel in one direction from the pre-synaptic to the post-synaptic neuron across a gap called a synapse. This is done to continue a nerve impulse so that it can reach its destination in the body. The process requires the use of a neurotransmitter, one of the most common is acetylcholine (ACh). Firstly the action potential reaches ...
