Would anyone be able to explain these different channels? I would like an explanation as to why voltage gated membranes are associated with axon membranes (although it's prob because of membrane potential differences and depolarization/hyperpolarization?), why ligand gated channels are primarily at synapses (via neurotransmitters?), etc.

All ion channels are primarily located at their respective sites depending on their response to that particular environment.
Basically there can be four such ion channels:
1. Ungated channels (leak)
2. Voltage gated channels (in axon membranes)
3. Ligand gated channels (primarily at synapses)
4. Mechanically gated (in sensory receptors)
These ion channels play important role in transmitting the signals and messages in our nervous system. Each channel has a unique way of functioning that makes it different from the others and thus are needed at specific locations.
