Question 2

List and describe the three types of channels found in the neuron membrane.

Accepted Answer

1. Voltage gated sodium and potassium channels: These channels open and close depending on voltage differences across the cell membrane.
2. Ligand gated sodium channels: These channels open and close when the correct chemical binds to them. In the case of the sodium channel, the presence of sodium ions would open the channel.
3. Mechanically regulated channels: These channels respond to physical distortions of the cell membrane.
