How Does a Nerve Impulse Travel Through a Neuron?

WebAn impulse is only transmitted if the initial stimulus is sufficient to increase the membrane potential above a threshold potential. Rather than staying constant, threshold levels in receptors often increase with continued stimulation, so that a greater stimulus is required before impulses are sent along sensory neurones. The receptor potential ... WebThe AP, a charge in the electrical potential associated with the propagation of an impulse along, in this case, the nerve cell, travels in one direction from the soma to the axon terminals. Thus, once the AP passes a certain area of an axon, that part must return back to its resting state. This is called repolarisation. smart home disney movieWebHow are sound waves captured?
