Describe how a nerve impulse is transmitted from one neuron to the next

The transmission from one neuron to another is characterized by exchange of electric charge across the membrane of each neuron (Fields, 2014). An unstimulated neuron would be polarised (McCance 2014). In the polarized state, there is difference in the electric charge across the membrane. However, during exchange, a neuron is said to undergo polarization, wherein there is an excess of Na+ (sodium ions) outside and excess of K+ (potassium ions) on the outside (Fields, 2014). Nerve impulse is transmitted through the process of polarization, repolarization, and hyperpolarization (McCance 2014).
