WebNervous Transmission. When a neuron is not actively transmitting an impulse it is said to be resting. Potential difference across axon membrane is resting potential when a neuron is in resting state. The axon is said to be polarised as there is a potential difference - usually -70mV. Resting potential occurs because of the movement of sodium ... WebUnderstanding: • Nerve impulses are action potentials propagated along the axons of neurons. Nerve impulses are action potentials that move along the length of an axon as a wave of depolarisation. Depolarisation occurs when ion channels open and cause a change in membrane potential. The ion channels that occupy the length of the axon are ... portal bridging fibrosis
