When a nerve impulse arrives at the end of the axon, neurotransmitters are released and travel to the dendrite of another neuron, carrying the nerve impulse from one neuron to the next. The following steps describe what happens when a nerve impulse reaches the end of an axon. WebApr 10, 2024 · The vagus nerve is an essential nerve that connects the brain to various vital organs such as the heart, lungs, and digestive tract. Vagus nerve stimulation (VNS) through electrical impulses has been found to have therapeutic benefits for a range of medical conditions. VNS can be achieved through both invasive and non-invasive stimulation.
