1a. Explain how chemically regulated channels differ fromvoltage-regulated channels and the nature of excitatory andinhibitory postsynaptic potentials.
1b. Explain how ligand-gated channels are opened, usingnicotinic ACh receptors as an example.
1c. Explain how ligand-gated channels operate, using muscarinicACh receptors as an example.
1d. Describe where stimulatory and inhibitory effects ofmuscarinic ACh receptors occur and how these effects areproduced.
1e. Compare the properties of EPSPs and action potentials,identify where in a neuron these are
