a channel can be gated mechanically, voltage or by a ligand. When you hear a sound all three of these type channels are being utilized. Explain generally where/how each of these channels are being utilized starting from hearing the sound, through travelling down a nerve to transmission to another nerve.

With respect to the three structural types of neurons (unipolar, bipolar & multipolar): State which parts of each type of neuron receive information, which parts integrate information, and which parts conduct the output signal of the neuron. Describe the location of the cell bodies of each type of neuron within the nervous system.
